Set top, right, bottom, and left margins independently. Trim white borders from scans, remove headers/footers, or focus on a specific column or article region.
Specify margins in PDF points (1 point ≈ 0.35mm), the same unit print designers use. Hit exact trim sizes for booklets, journals, and standard print layouts.
One crop setting applies uniformly across the entire document. Useful for batch-trimming scans where every page has the same margin issue or fixed page layout.
Cropping uses PDF page boundary boxes — no re-rasterization. Text stays selectable, vector graphics stay sharp, and file size barely changes after the crop.
A 1000-page document crops in well under a second because crop boxes are metadata, not pixels. No long progress bars even for thick scanned books.
Crop operations run via pdf-lib in your browser. Floor plans, medical images, and confidential documents never get uploaded to any server.
