Why choose PDF99?
Genuinely free — no tricks
No subscription tiers, no premium features locked away, and no watermarks on any output. Every tool is fully functional at no cost, funded by a single ad per page.
Your files stay private
All uploads use SSL encryption. Files are deleted from our servers within one hour. Most tools process files entirely in your browser — nothing leaves your device.
Works on every device
Whether you're on a Windows laptop, a Mac, an iPad or an Android phone, every tool runs in your browser. No installation, no extension, no configuration.
Fast, browser-based processing
We use battle-tested open-source libraries — jsPDF, PDF-lib, PDF.js — that run locally. Speed doesn't depend on a server queue.
More tools coming regularly

Built for real-world use
We built the tools we needed ourselves — no limits, no friction, no watermarks. That philosophy drives everything we add.
