Browser PDF editor —edits run on your machine
A PDF editor in your browser. Keystrokes, font measurement, and layout all happen client-side. Files only travel for the initial render — never for the edit itself.

Rendering and rewriting happen in your browser. Keystrokes, font extraction, color sampling, undo — all local. Your file briefly transits temporary cloud storage for hosting and auto-deletes after 2 hours.
Browser PDF editor — FAQ
What's a browser PDF editor?+
A PDF editor where the actual editing happens inside your browser tab — using JavaScript and WebAssembly — instead of on a remote server. You get instant edits and your file doesn't have to make a round trip to the cloud each time you change a character.
Does the file ever leave my computer?+
Briefly. We upload it to temporary cloud storage so we can render the first page reliably across devices. The copy is auto-deleted after 2 hours. All keystrokes, font measurements, and layout work happen in your browser — those never get sent anywhere.
Why a browser PDF editor instead of a desktop app?+
No install, no updates, works on locked-down work laptops, works on Chromebooks, works on whatever browser you happen to be in front of. The trade-off is that very large documents (500+ pages) are slower than a native app — for most documents you'll never notice.
Which browsers does it work on?+
Any modern Chromium-based browser (Chrome, Edge, Brave, Arc), Firefox, and Safari. We test on the latest two versions of each. Internet Explorer is not supported.
