What is this tool?

PDF Crop renders the first page of an uploaded PDF using pdf.js so you can drag a selection box over it, then applies that same relative crop area to every page's crop box using pdf-lib's native page.setCropBox() — no rasterization, so the underlying content and text stay fully intact. Everything happens locally in your browser.

Common uses

FAQ

Does cropping remove content permanently?

No — pdf-lib's crop box only changes which part of the page is visible or printed. The original page content is technically still in the file, just outside the visible crop area.

Is the crop applied to every page?

Yes, the same relative crop area (in percent) is applied to every page, scaled to each page's own size.

Is my PDF uploaded to a server?

No, everything is read, rendered and rewritten entirely in your browser using pdf.js and pdf-lib — your file is never sent anywhere.
