Crop PDF Margins & Trim Borders Online
Trim margins, cut black scanner edges, and adjust page boundaries for clean printing and comfortable reading on tablets and e-readers. Draw a visual crop box with live preview, apply it to a single page or uniformly across the whole document, and export.

Frequently Asked Questions
Can I crop all pages uniformly?
Yes. Set your margin trim values once and apply them to every page in the document simultaneously — ideal for cleaning up a full scanned batch with identical borders.
Does cropping reduce PDF file size?
Cropping adjusts the visible viewport bounds without deleting content or degrading resolution, so file size barely changes. Use the Compress tool afterward if you also want a smaller file.
Can I undo a crop?
Before exporting, you can reset the crop box and start over freely. After downloading, keep your original file if you may need the uncropped version.
