About PDF Toolkit
We believe PDF tools should be free, unlimited, and respect your privacy — no exceptions.
Our Mission
PDF Toolkit was built with a single purpose: give everyone access to professional-grade PDF tools without the cost, account requirements, or privacy trade-offs that most services impose.
Whether you need to merge a few documents, compress a large file, or convert images to PDF, you shouldn't have to hand over your files to a third-party server or pay a monthly subscription fee to do it.
How It Works
Browser-based processing
Every operation runs directly inside your web browser using modern JavaScript APIs. There is no server involved in processing your files.
Files never leave your device
When you select a file, it is read directly into memory on your device. Nothing is uploaded. Your documents remain 100% private.
No limits, no sign-up
We don't impose file-size limits or daily quotas. Use the tools as many times as you need, without creating an account.
Completely free
All tools are free forever. The site is sustained by non-intrusive, privacy-respecting advertising — never by selling your data.
Our Privacy Philosophy
Most online PDF tools work by uploading your files to a remote server, processing them there, and then (hopefully) deleting them afterwards. This means your confidential documents — contracts, tax forms, medical records — pass through infrastructure you don't own or control.
PDF Toolkit is fundamentally different. Because we use client-side processing, your files never touch our servers. We physically cannot see, store, or leak your documents, because they are never sent to us in the first place.
The only data we collect is anonymized, aggregated analytics (via Google Analytics 4) so we can understand which tools are most useful and how to improve the product. You can decline this by clicking “Decline” in the cookie consent banner.
Technology
PDF Toolkit runs entirely in the browser using modern Web APIs:
- PDF-lib — a pure-JavaScript library for creating and modifying PDF files client-side.
- PDF.js — Mozilla's industry-standard PDF rendering engine, used for generating page thumbnails and previews.
- Static hosting — the site is served entirely from a CDN with no application server, meaning there is no backend that could receive or store your files.
