Rotate PDF Pages
Turn a sideways scan the right way up and save it that way for good. Rotate one page, a handful, or the whole document, then download a PDF that stays rotated in every reader.
Your PDF?Pages are rendered here on your device to make thumbnails. The file is never uploaded. Password-protected PDFs need unlocking first.

How to rotate a PDF
The rotation is written into the file, not just into your viewer.
Drop the PDF
Every page is rendered as a thumbnail so you can see which ones are the wrong way round.
Select and turn
Tick the pages that need it, or select all, then rotate left or right. Press twice for 180 degrees.
Save
Download the corrected PDF. The rotation is stored in the document, so it opens correctly everywhere.
Why rotation in your PDF reader never sticks
The complaint is always the same. You open a sideways scan, rotate it, close it, send it, and the person at the other end gets it sideways again. Nothing was broken and nothing was lost. Your reader simply rotated the view, not the document.
A PDF page carries its own rotation value in the page object, and that is the only thing other software reads. Most viewers, including the built-in ones in Chrome and macOS Preview, offer a rotate button that changes the on-screen presentation and never writes back to the file — sometimes it is not even saveable, because the file was opened read-only.
This page edits the page object itself with pdf-lib, so the value is written into the document you download. Open it in Acrobat, Preview, Chrome, a phone, or a printer queue and it is the right way up in all of them.
Two details that catch people out. Rotation is stored per page, so a scanned stack with one landscape table in the middle can be fixed without touching the rest. And rotating costs nothing in quality: no page is re-rendered, the content stream is copied as it is, so text stays sharp, stays selectable, and the file size barely moves.
