Building Privacy-First Browser Tools: How ToolForge Processes PDFs Without a Server

Abid niazi — Thu, 14 May 2026 06:54:30 +0000

Most "free" online PDF tools upload your files to their servers.
That means your medical documents, salary slips, financial records,
and confidential contracts are sitting on someone else's computer.

When I built ToolForge's 12 PDF tools, I made a hard decision: nothing
leaves the browser. Here's exactly how I built it and what I learned.

Why Browser-Only Matters

When you compress a PDF on most free tools, here's what actually happens:

Your file uploads to their AWS/Google Cloud bucket
Server-side code processes it
Processed file downloads back to you
Your original file sits in their storage (usually deleted after 24h... usually) For a salary slip, medical report, or legal document — this is a real privacy risk. Browser-only processing eliminates it entirely.

The Core Library: PDF.js + PDF-lib

I use two libraries for different PDF operations:

PDF.js (Mozilla) — for reading and rendering PDFs
PDF-lib — for creating, modifying, and manipulating PDFs

npm install pdfjs-dist pdf-lib

PDF Compression (Client-Side)

True compression requires re-encoding, which is complex client-side.
My approach: re-render each PDF page to a canvas at slightly reduced
quality, then rebuild the PDF from those images.

import * as pdfjsLib from 'pdfjs-dist';
import { PDFDocument } from 'pdf-lib';

async function compressPDF(file, quality = 0.7) {
  const arrayBuffer = await file.arrayBuffer();
  const pdf = await pdfjsLib.getDocument(arrayBuffer).promise;
  const newPdf = await PDFDocument.create();

  for (let i = 1; i <= pdf.numPages; i++) {
    const page = await pdf.getPage(i);
    const viewport = page.getViewport({ scale: 1.0 });

    // Render page to canvas
    const canvas = document.createElement('canvas');
    canvas.width = viewport.width;
    canvas.height = viewport.height;
    const ctx = canvas.getContext('2d');

    await page.render({ canvasContext: ctx, viewport }).promise;

    // Convert canvas to JPEG (this is where compression happens)
    const imageDataUrl = canvas.toDataURL('image/jpeg', quality);
    const imageBytes = await fetch(imageDataUrl)
      .then(r => r.arrayBuffer());

    // Add to new PDF
    const jpgImage = await newPdf.embedJpg(imageBytes);
    const newPage = newPdf.addPage([viewport.width, viewport.height]);
    newPage.drawImage(jpgImage, {
      x: 0, y: 0,
      width: viewport.width,
      height: viewport.height
    });
  }

  return await newPdf.save();
}

This achieves 40–70% file size reduction while keeping all pages intact.
Everything runs in the user's browser — no upload required.

PDF Merging

Merging is simpler — PDF-lib handles this natively:

async function mergePDFs(files) {
  const mergedPdf = await PDFDocument.create();

  for (const file of files) {
    const arrayBuffer = await file.arrayBuffer();
    const pdf = await PDFDocument.load(arrayBuffer);
    const pages = await mergedPdf.copyPages(pdf, pdf.getPageIndices());
    pages.forEach(page => mergedPdf.addPage(page));
  }

  return await mergedPdf.save();
}

Drop it in a <input type="file" multiple accept=".pdf">, call this
function, and trigger a download. That's the entire merge tool.

PDF Rotation

import { degrees } from 'pdf-lib';

async function rotatePDF(file, rotation = 90) {
  const arrayBuffer = await file.arrayBuffer();
  const pdf = await PDFDocument.load(arrayBuffer);
  const pages = pdf.getPages();

  pages.forEach(page => {
    const currentRotation = page.getRotation().angle;
    page.setRotation(degrees(currentRotation + rotation));
  });

  return await pdf.save();
}

Password Protection (Lock/Unlock PDF)

PDF-lib supports encryption. For locking:

async function lockPDF(file, password) {
  const arrayBuffer = await file.arrayBuffer();
  const pdf = await PDFDocument.load(arrayBuffer);

  // PDF-lib uses the standard PDF encryption spec
  const pdfBytes = await pdf.save({
    userPassword: password,
    ownerPassword: password + '_owner',
    permissions: {
      printing: 'lowResolution',
      modifying: false,
      copying: false,
    }
  });

  return pdfBytes;
}

For unlocking — you load the PDF with the user-provided password:

async function unlockPDF(file, password) {
  const arrayBuffer = await file.arrayBuffer();
  const pdf = await PDFDocument.load(arrayBuffer, { password });

  // Save without password
  return await pdf.save();
}

Handling Large Files

The main challenge with browser-based PDF processing is memory.
Large files (50MB+) can crash the browser tab. My solution:

// Check file size before processing
const MAX_SIZE_MB = 50;

if (file.size > MAX_SIZE_MB * 1024 * 1024) {
  setError(`File too large. Maximum size is ${MAX_SIZE_MB}MB.`);
  return;
}

// Process in chunks for multi-page documents
const CHUNK_SIZE = 10; // pages per chunk
for (let i = 0; i < totalPages; i += CHUNK_SIZE) {
  await processPageChunk(i, Math.min(i + CHUNK_SIZE, totalPages));
  // Small delay to prevent UI freeze
  await new Promise(resolve => setTimeout(resolve, 10));
}

The Result: 12 PDF Tools, Zero Server Uploads

ToolForge now has 12 browser-based PDF tools:
Compress, Merge, Split, Rotate, Lock, Unlock, Watermark,
Sign, PDF↔Word, PDF→JPG, PDF→Excel, Image→PDF.

Every single one processes files locally. No data ever leaves your browser.

The full toolkit is free at freetoolforge.org/tools/document-tools

How I Built a Free CGPA, MDCAT & Merit Calculator for Pakistani Students

Abid niazi — Thu, 14 May 2026 06:52:09 +0000

Pakistani students get ignored by most tools on the internet.

Every CGPA calculator uses the US 4.0 grading scale. Every merit calculator
doesn't know what NUST or FAST or MDCAT is. Every EMI calculator shows
interest rates in USD.

So I built ToolForge — a free toolkit specifically for Pakistan. Here's what
I learned building three of its most-used calculators.

The CGPA Calculator Problem

Pakistan's Higher Education Commission (HEC) uses a grading scale that's
subtly different from the US system most calculators are built on.

The key difference: in Pakistan, both A and A+ map to 4.0 grade points.
In the US, A+ is sometimes 4.3. This sounds minor but it causes significant
errors when students use US-based calculators for Pakistani universities.

Here's the HEC scale:

A+ = 4.0  (90–100%)
A  = 4.0  (85–89%)
A- = 3.7  (80–84%)
B+ = 3.3  (75–79%)
B  = 3.0  (70–74%)
B- = 2.7  (65–69%)
C+ = 2.3  (60–64%)
C  = 2.0  (55–59%)
F  = 0.0  (below 50%)

The CGPA formula itself is straightforward:

function calculateCGPA(subjects) {
  const totalWeightedPoints = subjects.reduce((sum, subject) => {
    return sum + (subject.gradePoints * subject.creditHours);
  }, 0);

  const totalCreditHours = subjects.reduce((sum, subject) => {
    return sum + subject.creditHours;
  }, 0);

  return (totalWeightedPoints / totalCreditHours).toFixed(2);
}

The tricky part was building the UI to dynamically add/remove subjects
while keeping the calculation reactive. I used React state with an array
of subject objects:

const [subjects, setSubjects] = useState([
  { id: 1, name: '', grade: 'A', creditHours: 3 }
]);

Try the live calculator: freetoolforge.org/tools/calculators/gpa-calculator

The MDCAT Aggregate Calculator

MDCAT (Medical and Dental College Admission Test) uses a specific formula
that most calculators get wrong:

MDCAT Merit = (Matric % × 10%) + (FSc % × 40%) + (MDCAT Score × 50%)

Different universities then apply their own cutoffs on top of this aggregate.
I built a version that calculates the standard PMC formula and shows you
which universities you're likely eligible for based on last year's cutoffs.

function calculateMDCATAggregate(matric, fsc, mdcatScore) {
  const matricWeight = (matric / 100) * 10;
  const fscWeight = (fsc / 100) * 40;
  const mdcatWeight = (mdcatScore / 200) * 50;

  return (matricWeight + fscWeight + mdcatWeight).toFixed(2);
}

Live tool: freetoolforge.org/tools/calculators/mdcat-aggregate-calculator

The Merit Calculator Challenge

The Merit Calculator was the hardest to build — not because of the math,
but because every Pakistani university has a different formula:

NUST: Entry test 75% + FSc 15% + Matric 10%
FAST: Their own aptitude test with its own weighting
UET Lahore: Matric + FSc + UET entry test
LUMS: SAT-based, entirely different system I ended up building it with a dropdown to select the university, then dynamically rendering the correct formula and input fields.

The key technical decision: I stored all university formulas in a config
object rather than hardcoding them, so adding a new university is just
adding an object entry:

const UNIVERSITY_FORMULAS = {
  NUST: {
    label: 'NUST',
    formula: (matric, fsc, entryTest) =>
      (matric * 0.10) + (fsc * 0.15) + (entryTest * 0.75),
    fields: ['Matric %', 'FSc %', 'NET Score (out of 200)']
  },
  UET: {
    label: 'UET Lahore',
    formula: (matric, fsc, entryTest) =>
      (matric * 0.10) + (fsc * 0.40) + (entryTest * 0.50),
    fields: ['Matric %', 'FSc %', 'UET Entry Test %']
  }
  // ... more universities
};

What I Learned Building Pakistan-Specific Tools

1. Context is everything.
A generic calculator is useless to a Pakistani student. Pakistan has its own
grading scales, tax slabs, bank rates, and admission formulas. Building
for a specific context — even a smaller audience — gives you users who
are deeply engaged because the tool actually works for their situation.

2. Privacy matters more than people admit.
All ToolForge calculations happen in the browser. No data is sent to any
server. Users don't have to worry about their salary, CGPA, or tax info
being stored anywhere. This was a deliberate design choice and users
genuinely appreciate it.

3. SEO for specific audiences is easier.
"CGPA calculator" is a competitive keyword globally. "CGPA calculator
Pakistan HEC scale" is almost entirely uncontested. Building for a specific
audience means you rank faster with less effort.

The Stack

Next.js 14 App Router with TypeScript
Tailwind CSS for all styling
Vercel for deployment
Google Gemini API for AI-powered tools (with key rotation)
All calculations run client-side — zero database The full toolkit is live at freetoolforge.org — 50+ free tools, no signup, no ads. I'd love feedback from Pakistani developers and students on what to build next.

🚀 I Built 40+ Free Developer & Productivity Tools — Here’s What Actually Worked

Abid niazi — Fri, 01 May 2026 20:33:35 +0000

🚀 I Built 40+ Free Developer & Productivity Tools — Here’s What Actually Worked (And What Didn’t)

When I started building small tools for the web, I had one simple goal:

👉 Create useful tools that solve real problems — fast, free, and without friction.

What started as a few experiments turned into a full platform:
🔗 https://freetoolforge.org/

Today, it hosts 40+ tools used by students, developers, and everyday users.

But the real story isn’t the tools — it’s what I learned building them.

💡 Why I Decided to Build Free Tools

Most online tools today have one or more of these problems:

Hidden paywalls
Forced signup
Slow or bloated UX

I wanted to build something different:

⚡ Instant tools (no login)
🧠 Simple UI (zero learning curve)
🔓 Completely free

That philosophy shaped everything.

🔥 The Tools That Got the Most Traffic

Here are a few tools that performed surprisingly well:

🎓 GPA Calculator (Pakistan-focused)

🔗 https://freetoolforge.org/gpa-calculator

Solves a real student problem
Targets a specific audience
High search demand

👉 Lesson: Niche + localization = traffic

💻 Online Compiler

🔗 https://freetoolforge.org/online-compiler

Used by beginners and quick testers
Eliminates setup friction

👉 Lesson: Reduce effort → increase usage

📄 PDF Tools (High Volume Category)

🔗 https://freetoolforge.org/tools/document-tools

Includes:

PDF Compressor
PDF to Word
Lock PDF
Merge & Split tools

👉 Lesson: Utility tools = evergreen traffic

💰 Zakat Calculator (Localized + Seasonal)

🔗 https://freetoolforge.org/zakat-calculator

High demand during Ramadan
Strong emotional + practical use case

👉 Lesson: Timing + relevance matters

📈 What Actually Drove Traffic

Here’s what worked:

1. SEO First Approach

Every tool targets:

Long-tail keywords
Problem-based queries

Example:

“how to calculate gpa in pakistan”
“compress pdf without losing quality”

2. Programmatic SEO (Game Changer)

Instead of writing 100 blog posts manually:

I structured pages to scale automatically
Reused templates for multiple tools

👉 Result: More pages, more traffic

3. Zero Friction UX

No login. No delay. No confusion.

Users land → use tool → leave satisfied.

That alone increases:

Retention
Shares
Repeat visits

❌ What Didn’t Work

Let’s be honest — not everything worked.

1. Generic Tools Without Focus

Tools without a clear audience didn’t perform well.

👉 Lesson: Specific beats generic

2. Over-engineering Early

Spending too much time on features nobody asked for = wasted effort.

👉 Lesson: Build fast, iterate later

3. Ignoring Distribution Initially

Building tools isn’t enough.

You need:

SEO
Pinterest
Quora
Dev communities

👉 Traffic comes from distribution, not just development.

🎯 Key Lessons for Developers

If you’re planning to build something similar:

✔ Solve real problems

Not ideas — actual user pain points.

✔ Keep it simple

Fast tools win over complex platforms.

✔ Focus on SEO early

Traffic doesn’t come automatically.

✔ Build once, scale smart

Templates > manual work

🚀 What’s Next

I’m now focusing on:

Expanding to 100+ tools
Improving SEO structure
Scaling traffic through content + social platforms

🔗 Try It Yourself

If you want to explore or get ideas:

You might even find a tool you need.

💬 Final Thought

You don’t need a billion-dollar idea to build something useful.

Sometimes, solving small problems at scale is enough.

And honestly… that’s where the real impact is.
