How it works
Three steps. No queue.
01
Drop a file
The PDF stays in memory in this tab. We never open a network request to send it.
02
Run the tool
Compress, merge, sign, convert — WebAssembly and your CPU. AI tools send extracted text, or up to two page images when you opt into OCR.
03
Download and close
The result is yours. Close the tab and every byte of the original is gone.

Sign · 6 min
How to sign a PDF without Adobe, printing, or an account
Draw a signature, stamp it on the page, and download a signed copy that works the same on Windows, Mac, and phone.
AI · 7 min
