What is Crop PDF?
Crop PDF trims unwanted white margins, printer crop marks, header artifacts, and peripheral borders from PDF pages. Whether removing excessive whitespace from scanned book pages to optimize mobile reading, trimming shipping labels to fit thermal printers, or isolating specific engineering diagram callouts, this tool lets you define custom margin inset coordinates or drag visual cropping handles across page previews. You can apply crops uniformly across the entire file or target specific odd, even, or individual pages with precision.
