About this crop PDF online tool
Scans often include thick white borders. LovePDF.online lets you crop PDF margins in your browser. Set one margin for all sides or tune top, right, bottom, and left separately, then download a tighter document.

How it works
LovePDF adjusts each page crop box and media box with pdf-lib. Larger margins remove more edge area. Keep margins modest so important content is not clipped.

Add the file that needs tighter margins.
2.Set crop margins
Use one value for all sides or unlock sides for custom trimming.
3.Crop and download
Run Crop PDF and save the trimmed file.
