Crop PDF Online
Use PDF Magic to crop PDF online with precise margin controls. This free PDF crop tool lets you remove unwanted space from the left, right, top and bottom of each page, preview the result and apply the crop to the current page, the whole document or a selected page range.
Why crop PDF pages?
PDF files may contain oversized margins, scanner borders, blank areas or unwanted content near the page edges. Cropping creates a cleaner layout, improves printing and helps the important content fill the available page area.
Common uses for cropping PDF documents
An online PDF cropper is useful for scanned books, reports, invoices, worksheets, presentation handouts, exported documents and files with excessive white borders. It can also help prepare pages for printing or mobile reading.
How to crop a PDF online
Upload the PDF document from your device.
Choose manual margins or one equal margin value.
Select the page or page range that should be cropped.
Preview the result, apply the crop and download the edited PDF.
Using millimeter crop values
Small values remove narrow borders, while larger values can significantly reduce the visible page area. Keep a safety margin around text, page numbers and images to avoid cutting important content.
Cropping selected pages
Use the current-page option for individual corrections, all pages for consistent layouts and page range when only one section of the document needs the same crop.
PDF quality after cropping
Cropping changes the visible page boundaries rather than recreating the original document. The final result depends on the structure of the PDF and the processing library.
