About the tool

What is Crop PDF?

Cropping removes wasted white space so that text fills the screen on e-readers and phones, or trims scanner shadows and black borders from the edges of a scan.

The same margins apply to every page. The crop changes the visible area, while the underlying content stays in the file. For cleaner scans, combine with Rotate PDF to straighten orientation first.

Your files stay with you. This tool works inside your browser tab. Nothing you select is uploaded, stored or seen by us.

Frequently asked questions

What unit are the margins in?

Millimetres. 10 mm is about 0.4 inches.

Can I crop each page differently?
