How cropping works

The tool loads your PDF with pdf-lib and sets a smaller CropBox on each selected page, trimming the given percentage from the top, right, bottom and left. Viewers then display only the cropped region. The original content outside the crop box is preserved in the file, so nothing is destructively deleted.

Tips for clean results

Use the page range to crop only the pages that need it, for example 1,3-5. Keep margins under 45% per side so a visible area remains. Cropping works best on scanned documents and slides with wide white borders; it does not re-render or compress the page content.

PDF Crop Tool FAQs

Does cropping reduce the PDF file size?
Not much. Cropping only changes the visible page area (the CropBox); the original page content stays inside the file, so the size is nearly unchanged.
Will the cropped area be permanently removed?
No. The content outside the crop box is hidden, not deleted, and can be restored by resetting the CropBox in a desktop PDF editor.
Which pages does the page range accept?
Single pages (2), ranges (3-5) and mixes (1,3-5). Leave it blank to crop every page. Numbers are 1-based.
Does it work on password-protected PDFs?
Only on PDFs that open without a password. Encrypted files that require a password cannot be processed.
Is my PDF uploaded anywhere?
No. The file is read and cropped entirely in your browser; nothing is sent to a server.
