About Crop PDF
Scans arrive with wide black borders; slide exports carry wasted margins that shrink the content on a phone screen. Trim them here — the preview shows exactly what stays.
Frequently asked questions
Is the cropped area deleted?
By default it is only hidden (the crop box changes), so it can be restored. Tick 'remove permanently' to cut it out of the page for good.
Can I crop just one page?
Yes — enter that page number in Pages.
Does cropping reduce file size?
Only when you remove the area permanently and it contained images.
