About Crop PDF
Crop PDF trims a percentage-based margin from every edge of every page using pdf-lib's crop box, entirely in your browser. It's the fastest way to remove excess whitespace around scanned pages or printouts without editing each page individually.
Because the crop box only changes what's visible — not the underlying content — the operation is fast, lossless, and fully reversible by re-opening the original file.
Where excess margin comes from
Flatbed scanners frequently capture more page than the document itself — a sheet of paper scanned slightly off-center picks up a strip of scanner-bed gray or an uneven white border. Exported slides and reports can also carry more surrounding whitespace than makes sense once converted to a standalone PDF. Crop PDF removes a consistent percentage from every edge, tightening the page around its actual content, which also makes the document look noticeably more polished when printed or viewed on a smaller screen.
Why crop box, not re-rendering
Rather than rasterizing each page and cutting pixels — which would blur text and bloat file size — this tool adjusts pdf-lib's crop box, the same mechanism professional PDF software uses to control the visible viewport of a page. The underlying content is untouched and still there; only the boundary of what's displayed and printed changes, which is why the operation is instant even on long documents. Because the crop percentage is applied uniformly to every edge of every page, the result is consistent across the whole document, rather than requiring you to eyeball and adjust each page individually the way a manual image-editing workflow would.

Tips for the best results
- Start with a small margin like 5% and increase gradually — over-cropping can clip content close to the edge.
- Combine with Rotate PDF first if the scan is also sideways.
- For per-page, visual crop control, use Organize PDF instead.
- Cropped a document down for a slideshow? Follow up with Compress PDF if file size matters.
