About Crop PDF
Crop PDF trims the margins of your pages. Mark the area you want to keep and the tool cuts away the border around it. This removes wide white space and makes the content look larger when you read it on a phone or print it. The work happens in your browser, so your file never leaves your device.
It helps with scanned pages that have dark edges, slides with large empty borders, and e-books that look tiny on a small screen. You can also crop a scanned letter or certificate so only the useful part shows before you attach it to an email or upload it to a portal.
