Cropped PDFs Still Contain the Content You Hid

Cropping is the standard fix for a wide scan margin, and it does what it says: it changes the visible page area. What it does not do is remove the content outside that area from the file.

Why this comes up

Cropping is usually about presentation: a scan margin, a screenshot edge, a page that should start at the artwork. It becomes a privacy question when the trimmed area held something that should not travel.

Check before you run it

• Crop is not redaction. Content outside the crop box is hidden, not removed. A name, account number or note in the trimmed area is still in the saved file; use Redact when the data must actually go.
• Choose the mode from the page pattern. Use the same crop for a uniform document, odd and even when a bound scan has mirrored inner margins, and the listed pages when a cover or appendix should stay whole.
• Check the smallest text at the edge. A header, footer or page number that touches the box will look clipped. Leave a little air and confirm the page count did not change.

When to reach for it

• A scan carries a wide, uneven white border. Automatic maximum trim hugs each page's own content; a consistent trim is better when the pages must end up at one visible size.
• A screenshot brings browser chrome into the PDF. Crop to the content, then resize if the page itself has to become a standard sheet.

One question we get

Will cropping delete content?

The crop box hides what's outside it rather than deleting it — the page's underlying data stays in the file, and cropping a little less brings things back.

Where it fits

The tools people usually open next to Crop PDF:

• Split by pages — Split specific page ranges, or every page into a separate document.
• Extract Pages — Get a new document containing only the desired pages.
• Rotate PDF — Rotate and save PDF pages permanently.

Every tool works on a copy, so the original file is never touched. Uploads are stored under an unguessable id and deleted automatically two hours after you last open them; nothing is listed, shared or indexed. More on the security page.
