Crop PDF
Drag a crop box on the live preview — the same trim applies to every page.
Crop PDF trims margins by setting the crop box — the same crop, relative to page size, is applied to every page — and the content is not rasterised, so text stays text. Preview the crop before saving.
Crop PDF trims the margins of your pages by dragging a crop box over a live preview — in your browser, no upload. The same crop area is applied proportionally to every page. Cropping hides content outside the box; it does not delete it. To remove content permanently, use the Redact PDF tool instead. Crop PDF is one of UnboundPDF's 53 free browser-based PDF and image tools: it runs on your own device with no upload, no account and no watermark, and reports what it measured on the output.

Questions about Crop PDF 7
Are my files uploaded to a server?
No. UnboundPDF processes PDFs locally in the browser — documents are not uploaded to a server. We have no backend that receives, stores, or scans your files.
Is the same crop applied to all pages?
Yes. The crop box you set is applied relative to each page's size, so every page is trimmed the same way.
Is the cropped-away content deleted?
No. Cropping hides content outside the box rather than deleting it. If you need it permanently gone, use Redact PDF.
Does cropping delete the hidden area or just hide it?
It sets the visible crop box, so the trimmed area is hidden from view and print. The page content itself is not re-rendered.
Can I crop all pages the same way?
Yes. Set the crop once and apply it across the document for a consistent margin.
Will cropping lower the quality?
No. Cropping changes the page bounds, not the content, so text and images stay sharp.
Is there a free PDF cropper that works online?
Yes — Crop PDF runs entirely in your browser: no install, no account, no watermark, and no file-size tier tied to a paid plan. Set the crop box, apply it to one page or every page, and download the result from your own device.

How your files are handled
The work runs on your own device, inside the browser tab — so there is no server to send your document to.
- Nothing is uploaded. We have no backend that receives or stores documents, so we cannot see your files during processing or after.
- Your device does the work. Large documents are handled in stages, pages are rendered as you reach them, and each job is checked against your device before it starts — so a long run takes longer on a phone than on a laptop, nothing is queued behind other people's jobs, and you can stop a run at any point without touching your original file.
- No account and no watermark. The output is a clean file you can use anywhere, with no sign-up and no hourly cap.
