About CuroPDF
We believe PDF tools should be free, private, and fast. No tricks. No uploads. No limits.
Our Story
CuroPDF was born from frustration. Every "free" PDF tool on the internet had a catch: upload your files to their servers, create an account, hit a daily limit, or get a watermark slapped on your output. We built the tool we wished existed — one that respects your privacy and your time.
Launched in 2024, CuroPDF processes PDFs entirely in your browser using WebAssembly. Your files never touch our servers. Not even for a second. You can verify this yourself with browser DevTools.
What Makes Us Different
🔒 100% Private
All 44 tools run locally. Your confidential documents, legal contracts, and personal files stay on your device.
⚡ Lightning Fast
No upload/download delays. A 200MB PDF processes in seconds because it never leaves your browser tab.
💰 Actually Free
No credit card. No trial period. No "freemium" traps. All 44 tools are free forever with unlimited use.
🎨 Modern Design
Dark mode by default. Glassmorphism UI. Smooth animations. Built for 2026, not 2012.
By The Numbers
