How to rotate PDF pages
Fixing sideways scans permanently, why your reader's rotate button is not the same thing, and why it costs nothing.
In short
Rotate the whole document or individual pages and save. Rotation is a page property, so nothing is re-rendered — the file size does not change and the text stays sharp.
A scanner feeds a page in the wrong way and you get a document where some pages are sideways. Rotating in your PDF reader fixes your view and nothing else — close the file and it is sideways again for the next person.
Rotation is stored in the file
Every PDF page carries a rotation value alongside its content. Setting it to 90 tells any reader to display that page turned a quarter turn. The text, images and vectors underneath are not moved or redrawn.
- 01
Open the document
Every page appears as a thumbnail.
- 02
Rotate what needs it
Spin the whole document at once, or fix individual pages from the grid.
- 03
Save
The orientation is written into the file, so it opens correctly for everyone.
It survives everything downstream
Printing, merging and searching all respect the stored value. If you rotate pages and then combine documents, the orientation comes along.
Mistakes worth avoiding
- Rotating in your reader and assuming it saved. Most readers only change the view.
- Re-scanning a document to fix orientation. Rotating is instant and lossless.
- Rotating every page when only the even-numbered ones came out upside down — check the thumbnails first.
