FAQ

Frequently asked questions

Answers about security, formats, and limitations.

What units are used for margins?

Millimeters. For example, 20 mm equals 2 cm on each side.

Is all content in the margin area removed?

Visually yes — the area outside the new margin will not be visible. However, the data is not actually deleted from the PDF; it is hidden. To permanently remove data, convert to an image and back.

Can I crop only one side?

Yes. Leave zeros for the sides you do not want to crop — only enter a value for the side you need.

Is the crop applied to all pages?

Yes, uniformly across all pages of the document.

Can the tool remove margins from a scanned document?

Yes. This is a common use case: scans with wide white borders become more compact after cropping.
