How to crop PDF

  1. Drop the PDF.
  2. Let the printed area be found, or type the margins.
  3. Press Crop and download.

What happens to your file

Each page’s visible box is set — the CropBox readers and printers honour — either to the printed area found by rendering the page and trimming the white, with a small breathing space, or to the margins you typed. The page’s content is not touched: text stays selectable, nothing is redrawn, and the full page is one edit away in any PDF editor.

The printed-area finder reads up to sixty pages; longer documents take typed margins. A blank page keeps its size.

Questions

Will the file get smaller?

No — nothing is deleted, only hidden by the box. Cropping is for reading on a phone or printing without waste, not for size; use Compress PDF for that.

Can I crop a different area on each page?

The printed-area mode already does, per page. Typed margins apply to every page alike.
