How it works
Add a PDF and every page appears as a preview. Use the turn buttons under a page to rotate it a quarter turn left or right, or “Rotate all” to turn the whole document at once. The previews show exactly how the pages will look.
Rotation is saved in the PDF, so the pages open the right way up in every viewer and print correctly.
What gets kept
Rotating only changes each page's rotation setting. The page content isn't redrawn, so text stays selectable and images keep their full quality. Because the pages stay in order, bookmarks, links and form fields are kept too.
Your files are processed by your own browser, inside this tab. Nothing is uploaded, so there is no server copy to delete, and the page keeps working if you go offline after it loads.
