How to Rotate a PDF on iPhone (and Actually Save It)
Updated
Quick answer
Open the PDF in PDF Slayer, choose Organize, tap the sideways pages, and rotate them in the grid view. Save, and the rotation is written into the PDF permanently — anyone you send it to sees pages the right way up.
A scan comes in sideways, or one landscape page in a portrait report makes everyone tilt their head. The frustrating part on iPhone is not rotating the page — it is making the rotation stick when you save and share the file.
Viewer apps often rotate only your view, not the file. To fix the document for everyone, the rotation has to be saved into the PDF itself.

Launch PDF Slayer and open the file with the sideways pages.

Get PDF Slayer FreeRotate one page, several, or the whole document
Because the Organize tool shows the whole document as a grid, mixed-orientation files are quick to fix: rotate just the landscape pages, or select everything and rotate the entire document at once.
While you are in the grid you can also drag pages into a new order or delete blank ones — common cleanup for scanned documents.
Frequently asked questions
Why does my PDF still open sideways after rotating it?
Many viewers rotate only your current view. The fix must be saved into the file itself — PDF Slayer writes the rotation into the PDF so it opens upright everywhere.
Can I rotate just one page in a multi-page PDF?
Yes. Select only that page in the grid and rotate it; the rest of the document is untouched.
Does rotating reduce quality?
No. Rotation changes page orientation only — the content is not recompressed.
