About cropping PDF margins
Cropping trims the visible area of a page by a percentage on each side, which is handy for removing wide margins, scan borders, or headers and footers you do not want to print. Each slider crops the matching edge of every page, so the change is applied consistently across the whole document. The crop is set as a PDF crop box, meaning the area outside the box is hidden rather than deleted: the page count and order stay the same, and the content beyond the margins remains inside the file even though it no longer shows.
Is it private?
Yes. The cropper runs entirely in your browser using pdf-lib, a pure-JavaScript library. Nothing is uploaded, stored, or seen by us, and there is no server to send your file to.
Frequently asked questions
- How does cropping a PDF work here?
- Each slider trims that percentage off the matching edge of every page. The crop is applied as a PDF crop box, so the visible area shrinks by the amount you set while the page count and order stay the same.
- Is my file uploaded to a server?
- No. The cropping runs entirely in your browser using pdf-lib, a pure-JavaScript library. Your file is never sent anywhere, and there is no server involved.
- Does cropping permanently delete the hidden content?
- No. A PDF crop box hides the area outside the box without deleting it, so the crop is non-destructive. The content beyond the margins is no longer shown but remains inside the file.
- Is it free, and do I need an account?
- It is free with no watermarks, no daily caps, and no sign-up. Drop a file, set your margins, and download the result.
