You are told how many pages were turned and by how much. The rotation is added to whatever the page already had, so pressing 90° twice gives you 180°. If a page was already sideways in the file, it turns from where it was, not from zero.
Nothing is cut off and nothing is re-drawn. The text stays real text — you can still select, copy and search it afterwards, and the file size barely changes.
Almost always the scanner or the phone was held the other way round. The page is stored correctly, but with a rotation flag that some readers respect and others ignore. That is why a document can look fine on your phone and sideways when an office opens it. Setting the rotation here writes the correction into the file itself, so every reader shows it the same way.
Scanners and phone apps often save pages sideways or upside down, which makes a document awkward to read and unprofessional to send. Rotating fixes it permanently, so the file opens the right way up on every device. You can turn the whole document or just the pages that are wrong.
Crooked pages usually come from scanning. This helps:
