Crop controls

Measure margins against every page size

Margin cleanup

Documents with excess borders or scan edges

  • Removing scan shadows
  • Tightening presentation handouts
  • Preparing consistent page edges

Cropping changes the visible boundary; it is not secure content removal. Never use it to hide sensitive material. Review the privacy policy.

Crop troubleshooting

Prevent removed content and inconsistent boundaries

Text is cut off

Reduce the corresponding crop margin and return to the original.

Pages crop differently

The source contains mixed sizes; inspect representative pages.

The white border remains when printing

The printer may add its own non-printable margin.

Questions specific to this operation

Crop PDF questions

Does cropping delete hidden content outside the box?

Do not use cropping as secure redaction; use Redact PDF for sensitive content.

Can I crop in millimetres?

Yes. The tool uses precise margin measurements.

Does cropping resize the remaining content?

Cropping changes the visible page boundary rather than scaling the content.

Can I undo it?

The original remains unchanged; crop it again with different values.
