What is the PDF Cropper?
This tool helps you crop the pages of your PDF documents securely. The cropping logic runs entirely inside your browser cache — your files never touch any external server. You can select custom crop margins interactively or automatically crop out the white borders of your PDF document.
Common questions
Is the cropped-out content permanently deleted, or just hidden?
The visible boundary is what changes — every standard reader will only show and print within the new area. The underlying content-stream data for the trimmed-off region isn't separately stripped out, so file size may not shrink much even though the visible page is smaller.
Can I use the exact same crop on every page, even if pages are different sizes?
Yes — the fraction-based crop mode applies the same relative area, a percentage of each page rather than fixed pixel margins, so it stays sensible across mixed page sizes or orientations.
