How it works

Piddy runs entirely in your browser. When you open a file, it's read and edited on your own device using JavaScript — nothing is sent to a server. When you're done, the edited PDF is generated locally and downloaded straight to your computer.

Why private

Because your file never leaves your device, there's nothing to leak, store or lose. No account, no upload, no server-side copy of your document — ever.
