About the Crop PDF tool

Excess white margins eat screen space when reading on phones and tablets, and shrink the actual content when printing. Scanned documents especially arrive with wide empty borders around the content. This tool trims a percentage you set from each side independently — top, bottom, left, right — applying the crop to every page at once.

Cropping changes the visible frame without touching content quality, and everything processes in your browser with no upload. Keep your original copy if you might need the margins later — cropping produces a new file. To fix a wrongly oriented page rather than trim its edges, the Rotate PDF tool is the one you need.

When do you need this tool?

Comfortable mobile reading

Trim book and paper margins so text fills your phone screen instead of a thin strip amid whiteness.

Cleaning scan borders

Remove the black or empty borders scanners leave around documents.

Printing content larger

Crop margins before printing so the actual content expands and reads larger on the same sheet.
