10 Free PDF Tools Every Developer Should Bookmark in 2026

PDF work shows up in dev life more often than we'd like to admit — exporting docs, compressing build artifacts, merging client deliverables, or converting a spec sheet someone sent as a scanned PDF into something you can actually search. Paid suites like Adobe Acrobat are overkill for most of these one-off tasks.
Here are 10 free, no-signup tools that get the job done, ranked roughly by how often you'll reach for them.

1. ToolTiny — PDF to Word/Excel/PowerPoint

ToolTiny converts PDFs into editable DOCX, XLSX, or PPTX files directly in the browser, alongside the usual merge/split/compress/watermark/password toolkit. No account, no watermark on output.
What's actually useful for dev workflows: it handles presentation-style PDFs (think exported slide decks or design-heavy one-pagers) reasonably well — most converters flatten these into a single unreadable text blob, but ToolTiny keeps the layout intact while still giving you editable text. Good for the "client sent a PDF, I need it as a Word doc by EOD" scenario.

2. Smallpdf

The OG in this space. Smallpdf's PDF-to-Word conversion is excellent at preserving layout — it renders the page as a background image and overlays editable text boxes at the correct coordinates, which is why it handles complex layouts better than most. Free tier caps you at 2 tasks/day though.

3. iLovePDF

Similar feature set to Smallpdf, slightly more generous free tier. Their "Organize PDF" drag-and-drop page reordering is one of the smoother UX implementations out there if you need to quickly reshuffle a multi-doc PDF before sending it out.

4. PDF24

A German tool that's been around forever and quietly does everything — OCR, forms, signing, comparison. Less polished UI than the others but the OCR accuracy on scanned technical docs is genuinely strong.

5. Stirling-PDF

If you want something self-hosted, Stirling-PDF is the open-source answer. It's a Docker container you spin up yourself, giving you a full PDF toolkit (split, merge, compress, OCR, watermark, even API endpoints) with zero file ever leaving your infrastructure. The go-to choice if you're processing anything sensitive — contracts, financial docs, internal reports.

docker run -d -p 8080:8080 frooodle/s-pdf:latest

That's it. You now have a private PDF tool suite on localhost.

6. pdf2docx (Python library)

For when you need this baked into a pipeline rather than a website. pdf2docx converts PDF to DOCX programmatically, preserving tables, images, and basic layout:

from pdf2docx import Converter

cv = Converter("input.pdf")
cv.convert("output.docx")
cv.close()

Solid default behavior, and tunable via kwargs (clip_image_res_ratio, parse_lattice_table, etc.) if the output layout needs adjusting for unusual PDFs.

7. PyMuPDF (fitz)

The underlying engine a lot of these tools (including #6) are built on. If you need low-level access — extracting text with exact coordinates, font metadata, embedded images, or rendering pages to PNG — PyMuPDF is fast and well-documented:

import fitz

doc = fitz.open("file.pdf")
page = doc[0]
text_dict = page.get_text("dict")  # spans with position, font, color
pix = page.get_pixmap(matrix=fitz.Matrix(2, 2))  # render at 2x zoom

This is the building block for any custom PDF-to-something converter you'd ever write yourself.

8. pikepdf

For programmatic PDF manipulation — encryption, watermarking, page rotation, metadata stripping — pikepdf (a Python wrapper around qpdf) is more robust than pypdf for anything involving page-level transforms or repair of malformed PDFs:

import pikepdf

pdf = pikepdf.open("input.pdf")
pdf.save("output.pdf", encryption=pikepdf.Encryption(owner="pw", user=""))

9. Ghostscript

Old-school, but still the most reliable way to compress PDFs from the command line — useful in CI pipelines where you don't want a Node/Python dependency just to shrink a generated report before emailing it.

gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 \
   -dPDFSETTINGS=/ebook -dNOPAUSE -dQUIET -dBATCH \
   -sOutputFile=compressed.pdf input.pdf

/ebook gives a good size/quality tradeoff for everyday docs; /screen for aggressive compression.

10. LibreOffice headless

If your server already has LibreOffice installed, you get a free DOCX/PPTX/XLSX ↔ PDF converter via CLI — handy for batch jobs:

libreoffice --headless --convert-to pdf --outdir ./out input.docx

It's slower to spin up than the libraries above, but it's the most reliable way to get pixel-accurate Office-to-PDF conversion without paying for an API.

Picking the right one

One-off task, don't want to install anything → ToolTiny, Smallpdf, or iLovePDF
Sensitive files, need self-hosted → Stirling-PDF
Building this into your own app/pipeline → pdf2docx + PyMuPDF + pikepdf cover 90% of cases
CI/CD compression step → Ghostscript

Curious what other tools people have in their PDF toolbox — drop them in the comments, especially if you've found something good for table extraction, which is still the weakest link in most free converters.

Why I Built a Free Online Toolkit Instead of Another SaaS Product

Why I Built a Free Online Toolkit Instead of Another SaaS Product

Every day, millions of people perform small digital tasks that should take only a few seconds.

Convert a PDF.
Compress a document.
Translate a report.
Resize an image.
Generate a QR code.
Check an IP address.

Yet many solutions on the internet require users to:

Create an account
Subscribe to a monthly plan
Install desktop software
Upload files to multiple services

I kept asking myself a simple question:

Why isn't there one place where people can do these everyday tasks quickly and for free?

The Problem

While working in IT and supporting office users, I noticed the same requests appearing repeatedly:

How can I convert PDF to Word?
How do I compress a document before emailing it?
How can I translate an entire document without copying and pasting text?
How do I remove metadata before sharing a file?

Most users didn't need enterprise software.

They just needed a tool that worked.

Building ToolTiny

I started building ToolTiny as a collection of browser-based utilities designed to solve common office and productivity problems.

The goal was simple:

No registration
No installation
No unnecessary complexity
Accessible from any device

Today the platform includes tools for:

PDF conversion
Document processing
Image editing
Text utilities
Developer tools
Productivity tools

Privacy Matters

One of the biggest concerns people have with online tools is data privacy.

Many users hesitate to upload documents containing business information, reports, invoices, or internal files.

For that reason, privacy and minimal data retention became important design principles during development.

The Future

ToolTiny is still growing.

I'm currently expanding the PDF, document, and image tool collections while improving user experience and performance.

If you're interested in trying the project or sharing feedback, you can visit:

https://tooltiny.com

Or explore the PDF tools collection:

I'd love to hear what productivity tools you use most often and what features you'd like to see in the future.
