Wide margins waste space on small screens and e-readers, and scans often have dark borders or bits of the scanner lid around the edges. Crop PDF trims those areas by changing the visible page box, so readers see only the part of the page that matters.
Set the margins to trim from each side and apply them to every page or only selected ones. Cropping runs in your browser and your file is never uploaded.
Important: cropping hides content outside the new page area, but it doesn't delete it. The hidden content remains in the file and can be revealed by someone who resets the page box. If you're cropping to hide private information, use Redact PDF instead.

Frequently asked questions
Does cropping delete the content outside the crop area?
No. It only changes which part of the page is shown. The content is still in the file, so use Redact PDF if it must be removed.
Will cropping make my PDF smaller?
Not usually. The hidden areas remain in the file. Use Compress PDF if you need a smaller file.
Can I crop just one page?
Yes. Choose the pages to apply the crop to and leave the others unchanged.
Is my PDF uploaded to crop it?
No. Cropping happens in your browser.
