What this tool does

01

Crop all pages or a selected page range by adjusting PDF crop boxes locally. The operation is reversible in some PDF editors because it hides content outside the crop box rather than erasing drawing commands.

02

Use page-box cropping to remove scanner borders or focus a handout on its useful region.

03

Margins are entered in PDF points, where 72 points equals one inch.

Representative tasks

Where this tool earns its place

Remove a 24-point border

Apply 24 points to all four sides of every page.

Boundaries

What to check before relying on the result

  • Cropping hides out-of-box content and is not a secure redaction method.
  • One margin set is applied to all selected pages, including mixed-size pages.

How to use

01

04Download and inspect pages with different dimensions before publishing.

Use Cases

Trim scanner borders

Hide dark or uneven borders around a scanned packet.

Focus a slide export

Crop excess whitespace from PDF slides before placing them in another document.

FAQ

02
Does cropping permanently delete hidden content?

Not necessarily. This tool changes each target page's crop box; content outside it can remain in the PDF data.

What unit is used?

PDF points. 72 points equals one inch, or about 28.35 points per centimeter.

Can pages have different sizes?

Yes, but the same margins are applied to every selected page. Review mixed-size documents closely.
