How rotation stacks
Each page carries its own rotation setting, and whatever you choose here is added to what's already there — not replaced. A page already turned 90° that gets another 90° ends up at 180°, not back at 90°. If a page looks wrong after rotating, running it through again with the same or a different angle fixes it.
Rotation is a page instruction, not a redraw
Every PDF page carries a rotation value that tells the viewer which way up to display it. Rotating here changes that value rather than re-drawing the page, which is why the file comes back at the same quality it went in at and why the operation is quick even on long documents.
It also means nothing is lost. Text stays selectable, vector graphics stay sharp, and file size barely moves. Tools that rasterise a page to rotate it would give you a picture of your document instead — larger, blurrier, and no longer searchable.
Scanned documents are the common reason to need this. A scanner that fed a page sideways produces a file that opens rotated on every device, and readers who tilt their phone to cope are just working around it. Fixing the stored rotation once fixes it everywhere the file is opened.

Common questions
Can I rotate just some pages?
Yes. Choose "Specific pages" and enter the pages or ranges to rotate, such as 2, 5-7. Everything else is left exactly as it was.
What if a page is already rotated?
The rotation you choose is added to whatever rotation the page already has, so a page already turned 90 degrees plus a further 90 degree rotation ends up at 180.
Does rotating affect the page content or quality?
No. Only the page's rotation flag changes, which every PDF viewer respects when displaying it. The underlying content is untouched.
