Remove wide margins, scanner borders and print edges from any PDF. Set the trim in millimetres or percent, preview the new page size before you commit, and download the cropped file — the whole job happens in your browser, so your document is never uploaded anywhere.
No file selected
Margins are absolute millimetres: the same trim is applied to every selected page, whatever its size.
Tip: cropping changes each page's visible area (its CropBox and MediaBox) — the content is not re-rendered, so text and images stay perfectly sharp and the original file on your disk is never modified.
Most big-name crop tools — Adobe's online tools, iLovePDF, Smallpdf and similar — work by uploading your document to their servers, processing it there, and letting you download the result. Their policies promise deletion afterwards, but the file still made the round trip. For contracts, ID scans and client paperwork, that trip is the risk.
Here, the PDF is opened, trimmed and saved by JavaScript running in this browser tab. There is no upload to wait for and nothing of yours on any server. Close the tab and nothing remains anywhere. You can verify it in your browser's Network tab — and our safety guide explains the difference in plain terms.
Server tools pay for bandwidth and storage, so they gate heavy use behind accounts and paid plans. A browser-only tool has no file to store, so there is nothing to meter: crop a 2-page letter or a 300-page scan, as often as you like, with no watermark on the result.
We cannot store, leak or share documents we never receive. That makes this the safe default for accountants, freelancers and anyone trimming documents that contain personal data — the processing simply never leaves the data subject's own machine.
Drop your PDF into the tool above, type the margins you want to trim from the top, bottom, left and right — in millimetres or percent — then press Crop & Download. Your browser rewrites each page's crop box locally and saves a new PDF. It is free, unlimited and needs no account.
No. This tool runs entirely in your browser using the open-source pdf-lib library. The file is opened on your own device, the margins are trimmed locally, and the result downloads straight from the page — nothing is uploaded, stored or tracked.
Cropping trims the edges of the page: the page box gets smaller and the content inside keeps its original size and sharpness. Resizing (scaling) shrinks or stretches everything on the page to fit a different page size. Crop when you want to remove margins, headers or scan borders; scale when the whole page must fit a different format.
Yes. In the Pages to crop field, enter ranges such as 1-3, 5 and only those pages are trimmed — the rest keep their original size. Leave the field on 'all' to crop every page, which is what you want for removing scanner borders or printer margins throughout a document.
Millimetres are absolute: 10 mm trims exactly 10 mm from that edge of every selected page, whatever its size. Percent is relative to each page's own width and height, which is safer when a document mixes sizes such as A4 and Letter. On an A4 page, 10 mm is roughly 3–5% of the page.
No. Cropping only changes each page's CropBox and MediaBox — the text, images and vectors inside are not re-rendered or compressed, so everything stays exactly as sharp as the original and the file size barely changes.
Not permanently. Cropping hides the margins: readers and printers show only the cropped area, but the trimmed content can still exist inside the file. If you need content gone for good — for example personal data in a header — use our Redact PDF tool instead, which removes it permanently.
Yes. The tool works on any standard PDF, including scans: set margins that cut inside the white border or the dark scanner edge and every page is trimmed the same way. It also removes the wide margins left by print-to-PDF exports so the text area uses the full page.
Fix sideways or upside-down pages — all pages or a range, at 90°, 180° or 270°.
