No. Everything happens in this browser tab, on your own device. There is no upload endpoint and no server-side processing, so the file never leaves your machine — you can disconnect from the network after the page loads and it still works.

Is the rotation saved permanently?

Yes. It is written to the page as its rotation, so every viewer will show it the right way up — unlike rotating inside a PDF reader, which usually only affects that session.

Rotate PDF pages

Scanned pages that came out sideways can be turned a quarter at a time. Unlike rotating in a viewer, the rotation is written into the saved file.

How to do it

Open the PDF.
Select a page in the thumbnail rail.
Rotate it with the toolbar buttons, or the [ and ] keys.
Download — the new orientation is saved into the file.

Why nothing is uploaded

Most online PDF tools work by sending your file to a server, editing it there, and sending it back. That means contracts, medical records, bank statements and passports all end up on someone else's machine, and you are trusting a privacy policy about what happens next.

This editor does the work in your browser instead. The PDF is read by this tab, rendered with pdf.js and written back out with pdf-lib, both running as ordinary JavaScript on your own device. There is no upload endpoint, because there is no server doing any of this. Once the page has loaded you can disconnect from the network entirely and everything still works.
