Crop PDF
Trim a PDF page down to just the part you want to keep — cut wide margins, isolate a chart, or remove a scanner's border. Upload a file, drag a box over the preview to select the area to keep, and choose whether to apply it to just that page or every page proportionally. The crop is applied instantly with pdf-lib, no server involved.

Frequently asked questions
Does cropping delete content outside the box?
No. Cropping only changes the page's visible boundary — content outside it is hidden from view and printing, not deleted from the file.
Can I use the same crop on every page?
Yes. Check "apply to all pages" and the selection is scaled proportionally to each page's own dimensions.
Will this resize my pages?
No — the page size (as far as most viewers report it) becomes the cropped area, but nothing inside is scaled or stretched.
