How do I delete one page from a PDF?
Drop the PDF, press × on that page’s thumbnail and save. The other pages are copied into the new file unchanged, so nothing else about the document moves or blurs.
Can I get a deleted page back?
Before saving, yes: press Put back on the empty tile where it stood, or put every removed page back at once. After saving, the original is still on your disk, since nothing is changed in place.
How does Remove blank decide a page is empty?
Each page is drawn at 36 dpi and read for ink, leaving out its outer edge, where a scanner’s shadow, punched holes and a page number sit. Writing showing faintly through from the other side does not count, and a line of type does.
