Crop PDF pages
Three ways to crop: drag a box exactly where you want it, type precise margins in millimetres, or let the tool find the white edges automatically — on every page at once.
How it works
- Drop your PDF and choose a method: drag a crop box on the preview, trim margins by typing millimetres, or auto-trim the white margins.
- Choose the pages. All pages, just the current one, or a range like 1,3-5.
- Crop & download. Page sizes shrink to the cropped area; the content inside is untouched.
Frequently asked questions
Is cropping permanent?
No — it sets the page's crop box, which hides everything outside it in every viewer and when printing. The hidden content still exists in the file, so cropping is reversible. If you're cropping away something confidential, use Redact PDF instead — that removes content permanently.
What does auto-trim do?
It renders each page, finds the bounding box of the actual content, adds a small padding, and crops each page to its own content — perfect for scans with big uneven white borders.
My pages have different sizes — what happens?
A dragged crop box is applied proportionally to each page, so it covers the same relative area. Margin trimming and auto-trim are computed per page in absolute terms.
What's the difference from Resize PDF?
Resize changes the paper size and scales content to fit (A4 → Letter, adding margins). Crop cuts a window out of the existing page without scaling anything.
