About PDF Tools
Our Mission
We believe everyone deserves access to powerful PDF tools without compromising their privacy. PDF Tools is a free, open-source project that processes all files directly in your browser — nothing is ever uploaded to a server.
How It Works
Unlike traditional online PDF tools that require uploading your sensitive documents to remote servers, PDF Tools uses modern browser technologies (Web Workers, pdf-lib, pdf.js) to perform all operations locally on your device. Your files never leave your computer.
Why Choose Us
100% Browser-Based — No file uploads, no server processing
Free Forever — No subscriptions, no hidden fees, no account required
Privacy First — Your documents stay on your device at all times
Fast & Reliable — Powered by modern web technologies for instant results
How we build trust
Maintained as an open-source utility
PDF Tools is maintained as an open-source PDF utility project for people who need quick document tasks without sending files to a server.
Local browser processing
The tools use browser APIs and Web Workers so PDF operations happen on your device instead of a remote processing service.
Built with established libraries
Core PDF operations use libraries such as pdf-lib and PDF.js, with the application built on Next.js and TypeScript.
Feedback and issue reports
If something does not work as expected, include the tool name, browser, file type, and a short description when contacting us.
