Why use these tools?
Complete privacy
Files are processed in your browser using WebAssembly. No server uploads — your document never leaves your computer from the moment you load it to the moment you download the result.
No limits
No paid tiers, no file count limits, and no mandatory sign-up. All 101 tools are available immediately and for free.
Lossless quality
Merge, split, and rotate operations don't re-encode PDFs — pages are copied as-is. Font, image, and vector graphic quality is never degraded.
Frequently Asked Questions
Are all PDF tools free?
Yes. All 101 tools are completely free — no file limits, no paid plans, and no sign-up required.
Is it safe to use online PDF tools?
Yes. All operations run directly in your browser using WebAssembly and JavaScript. Files never leave your device — they are not sent to any server and are not stored anywhere.
Do these tools work on mobile?
Yes. All tools work in mobile browsers — Chrome, Safari, Firefox on Android and iOS. For large files, a desktop computer is recommended.
Why don't files get uploaded to a server?
The tools use PDF.js, pdf-lib, and other libraries that run entirely client-side. This means processing happens in your browser's memory without any data transfer.
How are these tools different from Adobe Acrobat?
Adobe Acrobat is a paid desktop application. Our tools run in the browser, are free, and require no installation. For most everyday PDF tasks, this is more than sufficient.
