How To Crop A PDF - Trim Margins And Scanner Borders
Scanned documents come with margins. Sometimes huge ones. The white space around the actual content wastes paper if you print, wastes pixels on a phone screen, and looks unprofessional in a presentation.
Crop PDF trims those margins off in one pass. Specify how many millimeters to cut from each edge, click, done.
When To Use Crop
Crop is the right tool when a uniform amount needs to come off every page - typical of scanner output, where every page has the same border. For varying margins or per-page cropping, Crop in v1 isn't the right tool.
If your goal is to fit the content on a different page size, Resize PDF is what you want. Crop adjusts what's shown; Resize adjusts the sheet size.
Does Crop Discard The Content
Crop adjusts the crop and media boxes of each page, so viewers and printers won't show the trimmed margins. The underlying content is still inside the PDF file, just not displayed.
True destructive cropping - where the trimmed content is actually removed from the file - is on the roadmap. For most use cases, the current crop is sufficient because no PDF reader will ever show the trimmed area.
How To Crop
Drop your PDF into Crop PDF. Enter the millimeters to trim from each of the four edges. Click Crop. Download the result.
25.4 mm equals one inch. A typical scanner border is 5 to 10 mm. Overdo it and you'll cut into content - undo by re-running with smaller values.
