PDF Splitter

Your files are processed locally in your browser and are not uploaded to our servers.

The PDF Splitter runs as JavaScript on the page you are reading. When you choose a file, the browser hands it to that code directly — it is never put into a network request, so there is no upload to cancel, no copy sitting in a queue somewhere, and nothing for us to delete afterwards. We could not see your file if we wanted to.

You can verify this rather than take our word for it: open your browser’s developer tools, switch to the Network tab, and run the tool. You will see no request carrying your file. Better still, once the page has loaded you can disconnect from the internet entirely and the PDF Splitter will keep working — which it could not do if it depended on a server.

To be exact about what doesleave the page: like the rest of this site, it loads analytics, which record that a tool was opened and whether it succeeded. Those events carry the tool’s name and a duration — never a file, a file name, or anything read out of your file. The tool panel above is also excluded from session recording, so nothing shown inside it is captured either.
