What Crop PDF does

Trims a fixed margin off every side of every page. Removing excess white space or scan borders from every page of a PDF is a common cleanup step before printing or sharing a scanned document. A fixed margin is trimmed from each side, with independent control over the top, bottom, left, and right amounts, measured in points — the standard PDF measurement unit.

Frequently asked questions

What unit are the margins in?

Points — 72 points equal 1 inch, the standard PDF measurement unit.

Can I crop different amounts on each side?

Can different pages have different crop amounts?

The same margin values are applied uniformly across every page in a single run — for page-specific cropping, process different page ranges separately.
