常见问题解答

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.
