PDF Merge & Split: The $19 One-Time Alternative to Smallpdf

Jack Green — Wed, 29 Jul 2026 05:55:20 +0000

The Problem With Smallpdf and Similar Services

Most online PDF tools like Smallpdf, iLovePDF, and Adobe Acrobat Online work the same way: you upload your files to their servers, they process them, and you download the result. This means:

Your data leaves your device — sensitive documents are temporarily stored on third-party servers
Subscription traps — features are locked behind monthly payments ($12–$25/month)
Privacy concerns — who knows what they do with your uploaded files
Usage limits — free tiers come with strict file size and daily quota restrictions

The Solution: 100% Browser-Based PDF Operations

Meet PDF Merge & Split — a completely client-side tool that runs in your browser. Your PDF never leaves your device. Not for a second.

Built with pdf-lib, the library powers all PDF operations directly in JavaScript. You drag and drop your files, and the app handles everything locally.

Key Features

Merge multiple PDFs into a single file — combine reports, contracts, or any documents
Split PDFs by page range — extract specific pages or sections (e.g., pages 1-3, 5, 7-10)
Zero uploads — processing happens entirely in your browser
No subscriptions — $19 one-time payment, forever yours
No tracking — no analytics, no cookies, no data collection
Works offline — once loaded, you can merge/split PDFs without internet
Supports all modern browsers — Chrome, Firefox, Safari, Edge

Pricing: Simple and Fair

$19.00 one-time — that's it. No monthly bills, no hidden fees, no expiring access.

Compare this to Smallpdf's Pro at $12/month ($144/year) or Adobe Acrobat's $23.99/month ($288/year). Over five years, you'd pay $720+ for alternatives — while PDF Merge & Split is yours for just $19.

How to Use It

Open PDF Merge & Split in your browser
Choose Merge to combine multiple PDFs, or Split to extract pages
Drag and drop your PDF files or click to browse
For splitting, enter page ranges like 1-3, 5, 7-10
Click the action button and wait for processing to complete
Download your merged or split PDFs — they're saved directly to your device

Try It First

You can use PDF Merge & Split for free — the merge and split features are completely available at no cost. The free version includes all core functionality; simply upgrade to Pro ($19) to remove the watermark and support continued development.

PDF Engine — Rust/WASM PDF Processing in Your Browser

Jack Green — Wed, 29 Jul 2026 05:55:16 +0000

Tired of $288/Year PDF Subscriptions? Try $19 Forever (Zero Uploads)

You open a cloud PDF editor, sign in, upload a tax return, wait thirty seconds, then wonder if someone's indexing your receipts. Stop it. In 2026 you should be able to merge two PDFs without handing over your document.

It's 2026 and we're still handing our sensitive documents over to cloud services just to merge two files or compress a PDF.

The Problem

Cloud PDF editors are convenient until you need privacy. Legal docs, tax returns, medical records — these aren't things you want floating around some startup's database. And the pricing is absurd: Adobe charges ~$20/month ($240/year), Smallpdf runs $15/month, most free tools cap you at 2–5 documents per day, and all of them want you to create an account first.

Subscriptions for PDF tools make zero sense when the operations themselves are simple: combine pages, split pages out, re-compress images. These are existing file format operations. They don't require servers.

The Solution

I built PDF Engine — a lightweight browser-based app that does everything you need and nothing you don't:

Merge multiple PDFs into one
Split PDFs by page range
Compress PDFs to reduce file size
100% client-side — your files never leave your device
Works offline — no internet needed after loading
No sign-up, no account, no tracking

Built with Rust compiled to WebAssembly using wasm-pack and the pdf-lib library. Everything runs in the browser using modern Web APIs. No upload step, no server processing — just open the URL and start working.

And the price? $19, once. No subscription, no limits, no hidden catches — just $19 and free updates forever.

How It Works

Everything runs on your machine using modern browser APIs. No upload step, no server processing — just open the URL and start working.

Built with Rust (compiled to WASM), vanilla HTML/CSS/JS, and deployed behind Nginx. Zero external dependencies on the server side.

Try the free demo at pdf-engine.example.com · Buy Pro — $19, one-time

Open Source Philosophy

The server code is open. The core PDF operations use well-documented PDF Reference specifications. No vendor lock-in, no "just works until the API changes" black boxes.

Because privacy shouldn't cost $240 a year.

I Paid $30/Month for Xnapper — Then Built a Free Alternative in One HTML File

Jack Green — Sat, 25 Jul 2026 16:52:20 +0000

I wasted $360 on Xnapper last year. $30/month for a macOS app that adds pretty backgrounds to screenshots.

Then I realized: it's just CSS gradients and canvas drawing. No server. No account. No subscription.

So I built Screenshot Beautifier — a free, client-side alternative that runs in any browser.

The Problem

Xnapper is great at what it does. But:

$30/month — that's $360/year for a tool that manipulates pixels
macOS only — Windows and Linux users are out of luck
Upload required — your screenshots go to their servers
Account wall — create an account just to beautify a screenshot

What I Built

Screenshot Beautifier does the same thing, differently:

Free demo — drag a screenshot, add a background, export. Done.
$9 one-time for HD export — cheaper than ONE month of Xnapper
100% client-side — your screenshots never leave your browser
Works everywhere — Chrome, Firefox, Safari, Edge on any OS
No account — just open the URL and go

How It Works

It's surprisingly simple. The entire app is one HTML file with inline CSS and JavaScript:

Drag & drop — loads the image into a hidden <img> element
Canvas API — draws the screenshot onto a canvas with your chosen background, shadow, and frame
Export — canvas.toBlob() downloads the result as PNG

The device frame presets (macOS window, browser window, phone) are just rectangles drawn on canvas before the screenshot. The blur backgrounds use CSS backdrop-filter on the canvas element.

Zero libraries. Zero dependencies. One HTML file.

Why This Matters

Screenshot tools are utilities, not products. You shouldn't pay monthly for something that boils down to ctx.drawImage().

This tool proves that simple utilities should be simple: free, fast, private, and works offline.

Try it at screenshot.jackgreen.top — no signup, no upload, no cost.

Fill & Sign PDF — Complete Any Form in Your Browser (No Uploads, No Server)

Jack Green — Sat, 25 Jul 2026 16:52:01 +0000

Professionals fill PDF forms every day — tax documents, contracts, applications. Most tools force you to upload sensitive documents to a server. That's unacceptable for legal and financial paperwork.

So I built Fill & Sign PDF: a tool you open in your browser, fill in any PDF form, add a signature, and download — all 100% client-side. No uploads. No accounts. No subscriptions.

The problem

Adobe Fill & Sign costs $12.99/month. Smallpdf charges $12/month. Both upload your documents to their servers. For tax forms, lease agreements, or medical documents, that's a privacy risk you shouldn't have to accept.

The solution: 100% in-browser

The entire app is a single HTML file. It uses:

pdf-lib for reading PDFs, extracting form fields, and embedding signatures
pdf.js for rendering the PDF preview in the browser

That's it. No server. No API. No data ever leaves your machine.

Features

Fill any PDF form field (text, checkboxes, dropdowns)
Draw or type a signature and place it on the PDF
Preview the filled PDF before downloading
Works offline in any modern browser
Dark mode support
No sign-up, no account, no tracking

Pricing

$9 one-time. No subscription. No recurring charge. Compare that to Adobe's $12.99/month ($156/year) or Smallpdf's $12/month.

Built the same way as Resume PDF Builder and PDF Tool — all client-side, all privacy-first.

I Built a Free QR Code Generator ($9 One-Time vs $15/Month Subscription)

Jack Green — Sat, 25 Jul 2026 13:27:46 +0000

I Built a Free QR Code Generator (Because Subscriptions Are Over)

If you've ever needed to generate a QR code — say, for a café menu, a business card, or a WiFi password — you probably Googled "QR code generator" and landed on one of those sites that ask you to create an account, upload your content to their server, and then either watermarks your result or demands $15/month for "pro features."

I got tired of that. So I built something better.

Meet QR Generator

QR Generator is a browser-based QR code creator that does one thing and does it well — and it works entirely on your device:

Generate QR codes for URLs, text, contacts, WiFi credentials, and more
Everything runs 100% client-side — your data never leaves your browser
No account, no signup, no tracking, no cookies
Offline capable — works with WiFi turned off
Custom colors, sizes, logo embedding (Pro upgrade)

Why This Exists

The incumbents in this space are built around subscriptions and data collection:

Tool	Price	Problem
QR Tiger	$12–$16/month	Monthly fees add up fast. Watermarked free tier. Cloud upload required.
QR Code Generator Pro	$15/month	Subscription trap. Your designs live on their servers.
Free online generators	Free	Uploads your content to unknown servers. Privacy nightmare.

QR Generator is different: $9 one-time for pro features. Not per month. Not per year. Once. You own it forever, including all future updates.

How It Works

Zero build step. Zero dependencies to install. The entire app loads as a single HTML file with the qrcodejs library from a CDN. Your browser generates the QR code using canvas rendering — no server round-trips, no API calls, no data exfiltration.

For the Pro upgrade, SVG export, higher resolution output, logo embedding, and bulk generation are unlocked with a single payment through Creem.io, our payment processor.

Privacy-First by Design

Here's what QR Generator doesn't do:

Doesn't send your QR code content to any server
Doesn't set cookies or track analytics
Doesn't require an email address or account
Doesn't watermark your output

What it does do:

Generates QR codes directly in your browser using JavaScript and Canvas
Respects your dark mode preference
Has a terms page and a privacy policy (seriously, some apps don't even have those)

Try It Free

Head over to qr.jackgreen.top and generate your first QR code. No account needed. Works on desktop, tablet, and phone.

And if you want the pro features? $9. One time. Not $180/year like the subscription tools. Compare that to QR Tiger's $144+/year or QR Code Generator Pro's $180+/year. That's 20× savings for life.

Built because I believe software should be simple, private, and yours — not a subscription you're forced to keep paying.

Building a 100% Client-Side PDF Merge & Split Tool (No Backend, No Sign-Up)

Jack Green — Sat, 25 Jul 2026 13:27:42 +0000

People merge and split PDFs all the time — extract a signature page, combine receipts, pull one diagram out of a 200-page report. Every online tool I found either uploads your files to a server (fine for public docs, bad for NDAs) or locks basic features behind a subscription.

So I built a tool that runs entirely in the browser. No backend. No sign-up. Your PDF never leaves your machine.

Here's how it works, and what it took to build.

The constraint that shaped everything: no backend

The entire app is static files: one HTML page, some CSS, and JavaScript loaded from CDNs. All PDF manipulation happens client-side using pdf-lib, a WebAssembly-compiled library that loads directly in the browser.

That constraint buys three things for free:

Privacy — your documents never touch a server. Not even logs.
Offline — works with WiFi off; useful on trains, planes, secure facilities.
Zero hosting cost — it's static HTML, so nginx serves it for free.

Merging PDFs

The core merge logic is about eight lines of code:

const merged = await PDFDocument.create();
for (const file of files) {
  const doc = await PDFDocument.load(await file.arrayBuffer());
  const pages = await merged.copyPages(doc, doc.getPageIndices());
  pages.forEach(p => merged.addPage(p));
}
const bytes = await merged.save();
downloadBlob(new Blob([bytes], { type: 'application/pdf' }), 'merged.pdf');

file.arrayBuffer() reads the uploaded file directly from the user's filesystem — no fetch, no XMLHttpRequest. Then copyPages + addPage stitches them together. pdf-lib handles the PDF structure, cross-references, and object streams under the hood.

Splitting PDFs

Splitting is the inverse: load one PDF, let users pick page ranges, write out new PDFs with just those pages:

const doc = await PDFDocument.load(fileBytes);
const rangeText = document.getElementById('split-range').value;
const pages = parseRanges(rangeText, doc.getPageCount());

// Group consecutive pages into separate downloads
const groups = [];
let cur = null;
for (const p of pages) {
  if (!cur || p !== cur.end + 1) {
    cur = { start: p, end: p };
    groups.push(cur);
  } else {
    cur.end = p;
  }
}

for (const g of groups) {
  const out = await PDFDocument.create();
  const indices = Array.from(
    { length: g.end - g.start + 1 },
    (_, i) => g.start - 1 + i
  );
  const srcPages = await out.copyPages(doc, indices);
  srcPages.forEach(p => out.addPage(p));
  const bytes = await out.save();
  downloadBlob(new Blob([bytes]), `pages-${g.start}-${g.end}.pdf`);
}

The tricky bits

Password-protected PDFs — pdf-lib can read encrypted PDFs if you pass userPassword, but stripping passwords requires knowing the password first. This is the #1 Pro feature request.
Large PDFs in memory — the browser has limits. A 50MB PDF can spike memory usage to 200MB+ during operations. Acceptable for most use cases, but worth documenting.
PDF.js for thumbnails — rendering page previews requires the much larger PDF.js library (~700KB gzipped). For v1, we show numbered blocks instead to keep load times snappy.

Design decisions

Browser over Electron

Most "desktop" PDF tools are really Electron apps wrapped around the same web tech. For privacy-focused users, a browser-based tool has better guarantees: no OS-level access, no sandbox escapes, no auto-updater you didn't approve. The user gets the same functionality with stronger privacy boundaries.

$19 one-time, not subscription

Smallpdf charges ~$15/month (~$180/year). We charge $19 once. The math is simple: if you use this more than two weeks, you've already beaten the subscription. And since it runs in your browser, "updates" are just new HTML/CSS/JS — free forever after purchase.

CDN-loaded libraries

pdf-lib loads from cdn.jsdelivr.net. That's one HTTP request, ~300KB gzipped. Caches well, no server processing needed. Trade-off: requires internet on first load. We accept that — the alternative is shipping a 10MB native app.

Open source spirit

The free tier does everything — merge unlimited PDFs, split by page range, download instantly. The Pro tier ($19 one-time) adds advanced splitting: single-page extraction, rotation within splits, password-protected PDF support, batch rename. But the core tool is genuinely usable without paying.

Try it here: https://pdfmerge.jackgreen.top/?utm_source=devto&utm_medium=article&utm_campaign=pdfmerge-launch

If you're building something similar, pdf-lib's docs are excellent. The copyPages API is the workhorse — everything from merge to split to rotation boils down to copying pages between documents.

I Was Paying $30/Month for QuickBooks Just to Track 5 Receipts a Month

Jack Green — Sat, 25 Jul 2026 07:06:59 +0000

I Was Paying $30/Month for QuickBooks Just to Track 5 Receipts a Month

A client-side receipt tracker for freelancers who hate subscriptions.

I was paying $30/month for QuickBooks Self-Employed. Just to track about 5 receipts a month.

My annual bill: $360. My actual usage: a fraction of what I was paying for.

Sound familiar? If you're a freelancer, consultant, or solopreneur who only does a handful of invoices and expense receipts per quarter, you've probably felt the same subscription fatigue.

So I built something better.

Receipt Tracker

Receipt Tracker is a completely client-side receipt and expense tracker for freelancers. No signup. No account. No data ever leaves your browser.

$9 one-time. Free tier available.

Here's what it does:

Upload or snap a receipt photo — drag and drop, or use your phone camera
Categorize expenses — travel, meals, office supplies, software, and more
Monthly summaries — see where your money goes with visual breakdowns
Export to PDF — clean, organized receipt summaries for tax season
Export to CSV — standard format, no vendor lock-in

Why Client-Side Matters

Every other receipt app — QuickBooks, Xero, even the "free" ones — stores your financial data on their servers. You're trusting them with your income, your expenses, your business secrets.

Receipt Tracker runs entirely in your browser. Your data never touches a server. Not even once.

That means:

Privacy-first — your financial data stays yours
Works offline — after the first load, you don't even need internet
No account — no email, no password, no verification. Just open and use.
No lock-in — export to standard PDF or CSV. Switch tools anytime.

The Pricing

	QuickBooks	Xero	Receipt Tracker
Price	$30/month	$50/month	$9 one-time
Annual cost	$360	$600	$9
Data stored on servers	Yes	Yes	Never
Signup required	Yes	Yes	No

That's 2.5% of QuickBooks' annual price. Or 1.5% of Xero's.

Who Is This For?

Freelancers who track 1–50 receipts per year
Consultants who need simple expense logging
Anyone tired of monthly subscriptions for simple tools
People who care about privacy and want their data in their browser

Open Source

This is built as a single HTML file with inline CSS and JavaScript. Zero build step. Zero dependencies (except jsPDF for PDF generation). Just a static server serving one file.

The philosophy: the best code is the code never written. If you can solve a problem with one HTML file, why add a framework, a bundler, and a CI pipeline?

Try It

Or compare against your current tool:

30-day money-back guarantee. If it doesn't save you from subscription hell, I'll refund you. No questions asked.

I Built a Free Markdown-to-HTML Converter (Because Bear Costs $50/Year)

Jack Green — Sat, 25 Jul 2026 06:38:11 +0000

I Built a Free Markdown-to-HTML Converter (Because Bear Costs $50/Year)

If you've ever needed to convert Markdown to HTML, you probably did one of three things:

Opened a terminal and ran pandoc input.md -o output.html
Pasted your Markdown into Notion and exported it
Paid $50/year for Bear and hoped the export feature would work

None of those are great. So I built something better.

Meet md-to-html

md-to-html is a browser-based Markdown to HTML converter that does one thing and does it well:

Paste or type Markdown on the left
See live HTML preview on the right (debounced at 150ms)
Copy HTML to clipboard with one click
Download as a standalone .html file with embedded CSS
Drag & drop .md files directly into the editor
Dark mode that respects your system preference

Everything runs client-side. Your content never touches a server.

Why This Exists

The incumbents in this space are expensive or bloated:

Tool	Price	Problem
Bear	$50/year	Overkill for conversion. macOS/iOS only. Apple ID required.
Notion	$8-10/month	You're paying for a wiki to paste Markdown. Telemetry-heavy.
Typora	$15 one-time	Desktop app. Good, but why install anything for a simple conversion?
Online converters	Free	Upload your content to someone else's server. Privacy nightmare.

md-to-html is free at its core. No signup. No install. No telemetry. If you want premium features (custom CSS themes, template save/load, batch convert), it's $9 one-time — not $50/year, not $10/month.

How It Works

Zero build step. Zero dependencies to install. The entire app is a single index.html file that loads marked from a CDN and goes.

The editor uses a textarea with monospace font. The preview renders GFM-flavored Markdown with sensible default styles. The download wraps your HTML in a complete document with embedded CSS.

That's it. The best code is the code never written — and the best converter is the one that runs in your browser.

Premium Features ($9 One-Time)

The core conversion is free forever. Premium unlocks:

Custom CSS themes — swap the default stylesheet for something that matches your brand
Template save/load — save your favorite configurations and come back to them
Batch convert — drop a folder of .md files and get HTMLs for all of them
No watermark — exported HTMLs won't have the "Made with md-to-html" footer

Compare that to Bear's $50/year for... tagging and a nice UI. Your call.

Try It

Head over to md.jackgreen.top and paste some Markdown. No account needed. Works on any device with a browser.

And if you like it and want the premium features, grab them for $9. One time. Not a subscription.

Built with love (and a healthy dose of frustration at $50/year markdown editors).

PDF Tool — Free, Private, Browser-Only PDF Merge & Split

Jack Green — Fri, 24 Jul 2026 21:42:21 +0000

PDF Tool — Merge, Split & Optimize in Your Browser. No Uploads. No Signup. $0.

Every PDF task you'll ever need: Merge, Split, and Optimize — all running client-side in your browser. Your files never leave your machine. Not even once.

Live: https://pdf.jackgreen.top/?utm_source=devto

The cloud PDF trap

Smallpdf charges $15/month. iLovePDF locks 2-of-3 core tools behind signup walls. Adobe Acrobat starts at $18/year just to merge two files.

PDF Tool does everything for free. Right now. In your browser.

Feature	PDF Tool	Smallpdf	iLovePDF
Merge PDFs	✅ Free, unlimited	✅ $15/mo after 1 trial	✅ After signup
Split PDFs	✅ Free, unlimited	❌ Paywall	✅ After signup
Optimize (reduce size)	✅ Free, unlimited	❌ Paywall	❌ Premium only
Files uploaded to server	❌ Client-side only	✅ Yes	✅ Yes
Account required	❌ Never	✅ Always	✅ Yes

Privacy that actually means something

When you upload a contract to Smallpdf, their server touches it. When you use Adobe online, Adobe's cloud processes it. Even if they don't store it, it traversed someone else's wire.

PDF Tool uses pdf-lib — the entire PDF engine runs as JavaScript on your machine. Zero network requests for file data. After the page loads, you can even go offline and keep working.

This matters when your PDFs contain:

HR documents with salary bands
Legal agreements with NDAs
Financial statements
Anything you wouldn't want a third-party server to see, even briefly

Build vs buy math

Let's be real about the $19 one-time option. If you're a freelancer, consultant, or small team who touches PDFs more than three times a month:

Smallpdf annual cost: $15 × 12 = $180/year
PDF Tool Pro (one-time): $19

That's a $161 savings every year, forever. And the free tier already covers 95% of use cases indefinitely.

New: Side-by-side comparison pages

We recently built dedicated /vs/ pages so you can see exactly what you're trading off before you commit:

Each breaks down features, pricing, and privacy trade-offs so you can make an informed call.

How it works

The tool ships as a single-page app. Load https://pdf.jackgreen.top, pick your operation (merge, split, or optimize), drop your files in — that's it. No buttons to click, no accounts to create, no captchas to solve.

Everything happens in-memory via pdf-lib. There is no backend to scale, no database to manage, no secrets to rotate. This is the kind of architecture that stays fast because it has nothing to talk to.

Want to support the project?

The free tools will always be free and browser-only. If you need pro features (watermarking, OCR) or want to fund continued development:

Favicon Generator — Free, 100% Client-Side, No Upload

Jack Green — Tue, 21 Jul 2026 03:10:32 +0000

I wasted 20 minutes uploading images to Favicon.io just to get a 16x16 pixel icon. Then I realized I had to create an account for it. And the free tier is basically useless — the Pro plan is $29/month.

So I built a free alternative that runs entirely in your browser.

The problem with favicon generators

Most online favicon tools share the same flaws:

Upload required — your image goes to someone else's server
Account wall — create an account just to download a 32x32 PNG
Subscription pricing — $29/month for a tool that does pixel-perfect resizing
No offline support — you need internet just to generate a tiny icon

What I built

Favicon Generator generates favicons in every format you need:

ICO (16/32/48px) — multi-resolution, single file
PNG (16/32/48/180/192/512px) — every size you'd ever need
SVG — scalable vector wrapper
Apple Touch Icon (180x180) — iOS home screen
Open Graph (1200x630) — social media sharing

Zero JavaScript libraries. Zero dependencies. One HTML file.

How it works

When you drop an image, it uses the Canvas API to resize to your selected formats. Everything happens locally — no network requests, no server calls. Your images never leave your machine.

The ICO encoder is a ~40-line inline function that packs multiple PNG sizes into a single .ico file with proper headers. No library needed.

Why this matters

Favicon generation is a utility, not a product. You shouldn't pay monthly for it, and you definitely shouldn't need to upload your brand assets to a third-party server.

This tool proves that simple utilities should be simple: free, fast, private, and offline-ready.

Try it at favicon.jackgreen.top — no signup, no upload, no cost.
