How do I crop unwanted margins from a PDF?
Upload the document to the Crop PDF tool, draw or set the area you want to keep, apply it to the selected pages, and download the cropped copy. Check page edges, headers, footers, signatures, and print margins before replacing the source.
PDF pages sometimes include large white margins, scanner shadows, binding edges, or part of the surface around a photographed document. Cropping improves the visible framing and can make pages easier to read on smaller screens. It should be done carefully because edge content may differ from page to page.
Inspect the whole document first
Look for page numbers, footnotes, signatures, stamps, and handwritten notes near the edges. A crop that is safe for the first page may remove important material from later pages. Group pages by layout when they need different crop areas.

Use consistent margins
Leave a small border around text and images rather than cutting directly against them. Consistent margins give multi-page files a more intentional appearance. For printed documents, allow enough space for printers that cannot print to the paper edge.
Crop is not secure redaction
Cropping is intended for page framing. Content outside the visible crop area may remain recoverable in some PDFs. If sensitive information must be removed, use an approved redaction process and verify the result rather than relying on a crop box or a white shape.

Rotate sideways scans with Rotate PDF before cropping so boundaries are easier to set. Reorder pages with Organize PDF, then add page numbers only after the final page layout is approved.
Common questions
Does cropping a PDF permanently delete everything outside the crop box?
Cropping may change only the visible page area in some workflows. Do not use cropping as a secure redaction method for confidential information.
Can I crop all PDF pages to the same size?
Yes, when the pages share a consistent layout. Preview varied pages first so headers, footers, and edge content are not removed.
