How to Crop a PDF (Trim Margins and Whitespace)

Scanned documents and exported slides often come with thick margins or empty borders that waste space and look untidy. Cropping a PDF trims those edges so the content fills the page.

Cropping changes the visible page boundary (the crop box) without deleting any content — you are simply telling the PDF to show a smaller window of each page. That keeps it safe and reversible in principle, and it keeps text and images intact.

To crop a PDF with PdfWill: open the Crop tool, upload your file, set how much to trim from each side, and download. The same margins are applied to every page.

If your pages are also turned the wrong way, fix that with the rotate tool first. And to rearrange or drop pages after cropping, the page manager handles the layout.
