PDF tools that stay in your browser

Merge, split, compress, edit — every tool below runs on your own machine. Your files are never uploaded, because there is nowhere to upload them to: this site has no backend.

What is deliberately missing

No Word or Excel conversion
It needs an engine that would mean either a server or a 30 MB download, and neither is worth breaking the rule this page exists for.
Editing text only where it is safe
A line sharing a text block with others cannot be changed without moving them, and the tool says so rather than handing back a shifted page.
Whiteout covers, it does not redact
The text underneath stays in the file. So does what a deleted page shared with the pages you keep. Neither is a way to hide a secret.

Check it rather than trust it: open DevTools → Network and watch what happens when you run a tool. The only requests are this site’s own static files — opening a tool fetches the engine it needs, and the page renderer only when something has to draw a page. Nothing else ever leaves.
