Black out sensitive areas.
Black out sensitive information on specific areas of a PDF's pages — useful for hiding account numbers, personal details, or confidential sections before sharing a document.
x/y = position from top-left as % of page. width/height = box size as %. Example: "1: 10,15,50,8" blacks out a box on page 1.

Supported formats
Accepts standard PDF files (.pdf). Specify the page and region (as percentages) to black out.
Things to know
This draws an opaque black box over the specified region visually — verify carefully that your coordinates cover the intended content precisely, since an imprecise region could leave sensitive text partially visible at the edges.
