How to crop a PDF's margins
Upload your PDF and a preview of the first page appears with adjustable margin guides. Drag each slider to trim the top, right, bottom, or left edge — the dimmed area shows exactly what will be cropped out.
Once the margins look right, crop the PDF and every page is trimmed by the same proportions. This is handy for removing wide scanner margins, oversized whitespace before printing, or a stray edge that crept in during a previous export.
Frequently asked questions
Does cropping remove content, or just hide it?
Cropping sets each page's visible region (its CropBox) — the original page content underneath is untouched. Most PDF viewers and printers will only show what's inside the crop, but the trimmed content technically still exists in the file.
Can I crop each side by a different amount?
Yes — the top, right, bottom, and left margins are set independently, so you can trim a wide margin off one side and leave another untouched.
What happens if my PDF has pages of different sizes?
Margins are applied as a percentage of each page's own size, not a fixed measurement, so mixed page sizes are all cropped proportionally rather than using a box sized for one page.
Is there a page limit?
No fixed page-count limit, though very large files are subject to the site's file-size limits (20MB free, 100MB Premium) since everything processes in your browser.
