よくある質問 (FAQ)

Does cropping delete content permanently?

It changes the visible page boundary (CropBox). Most viewers and printers will only show the cropped area from then on.

Can I crop each side by a different amount?

Yes, top, bottom, left, and right each have independent sliders.

Will this work on scanned PDFs?

Yes — cropping works on any PDF page regardless of whether it contains text or a scanned image.
