Crop PDF
Trim white margins, cut a page down to the part you need or tidy up scans — drag the crop box or let auto-detect find the content. Runs in your browser; nothing is uploaded.
At a glance
- Drag the crop box on the page preview, or type exact margins in millimetres for the top, bottom, left and right.
- Auto-detect margins finds the empty white border around the content, checking up to 24 of the pages you are cropping, spread through the document.
- Crop all pages, this page, or a list such as “1, 3-5, even”.
- Cropping is lossless: text stays selectable and images keep their quality, because the pages aren’t redrawn.
- Cropping hides the area outside the box — that content is still in the file. Use Redact PDF to remove information for good.
- Rotated and landscape pages are cropped as you see them. Bookmarks, links and form fields are kept.
- Runs entirely in your browser with pdf-lib and PDF.js — the file is never uploaded.

Features
Everything you need, nothing you don’t
Trim white margins
Make slides, papers and e-books easier to read on a phone or tablet by cutting away wide empty borders.
Auto-detect
One click finds where the content starts and ends on your pages, with a little padding so nothing is clipped.
Exact sizes
Drag the box for a quick crop, or type margins in millimetres when you need a precise result.
Any pages
Crop the whole document, only the page you’re looking at, or chosen pages like “2-4” or “odd”.
No quality loss
Pages aren’t turned into images, so text stays sharp and searchable and the file size barely changes.
Private
Your PDF stays on your device. No upload, no sign-up and no watermark.
Crop, resize or redact?
| You want to… | Use |
|---|---|
| Cut away margins or keep part of a page | Crop PDF |
| Hide something for good — a name, number or signature | Redact PDF |
| Make the file smaller | Compress PDF |
| Turn sideways pages the right way | Rotate PDF |
Is cropped content really gone?
No. Like Adobe Acrobat and most PDF editors, cropping sets the visible area of each page; the content outside it is hidden but still in the file, and can be shown again in a PDF editor. That makes cropping reversible, but not safe for hiding sensitive information.
To remove an account number, address or signature permanently, use Redact PDF instead.
