特征
Instant
Cropping runs on your own device, so the result is ready at once, with no upload and no queue.
Nothing leaves
The document never leaves your browser: it is not uploaded to our server, so even a contract is safe to crop.
Every page at once
The frame is stored as a share of the page, so it lands correctly on A4 and landscape pages in the same file.
No quality loss
Text stays text instead of turning into an image: only the page boundaries change.
Free
No sign-up, no subscription and no watermark on the result. There is no limit on how many files you crop.
Any device
The frame is dragged with a mouse or a finger, so cropping on a phone works as well as on a computer.
How to crop a PDF and remove unwanted margins
A scanned document almost always arrives with slack around the edges: wide white margins, a shadow from the scanner lid, the edge of the next page. On screen it is a trifle, but in print or inside a report it stands out immediately.
Upload the file and the first page appears with a crop frame. Drag its corners to keep only what you need, or move the whole frame by its middle. The area applies to every page at once, and because it is measured as a share of the page, a document with mixed page sizes crops correctly.
Everything runs in the browser: the file is not uploaded and we do not store it. The tool works on Windows, macOS, Linux, Android and iOS — all you need is a browser.
常见问题
How do I crop a PDF online for free?
Upload the document, drag the frame by its corners and press “Crop and download”. No sign-up is needed and the result carries no watermark.
Does cropping apply to every page?
Yes, the frame you set applies to the whole document. Because the area is measured as a share of the page, files with mixed page sizes crop correctly.
Is my file uploaded to a server?
No. Cropping happens in your browser on your own device, and the document is never sent anywhere.
Will the quality get worse?
No. Only the page boundaries change; the content is not recompressed, so text stays text and images keep their original quality.
Can I undo the crop later?
Not in the downloaded file, so keep the original if you may need it. Before downloading you can reset the frame with one button.
How is this different from cropping in a viewer?
A viewer usually only changes what is displayed while the file itself stays the same. Here the page boundaries change inside the document, so the crop shows everywhere, printing included.
