PDF
Permanently black out a rectangular area on one page of a PDF — for hiding an account number, address, or any sensitive detail before sharing the document.
How to use Redact PDF
- Upload the PDF and note which page has the content to redact.
- Enter the page number and the box coordinates (X, Y, width, height in points).
- Tap Run — the box is drawn as a solid black rectangle directly into the page.
FAQ
How do I know what X/Y coordinates to use?
Coordinates are measured in points from the bottom-left corner of the page; it usually takes a little trial and error — try a rough guess, check the result, and adjust the numbers until the box lines up.
Is the redacted content actually removed, or just covered?
The black rectangle is drawn as a new shape on top of the page content — the underlying text or image data is not deleted from the file itself, only visually covered, so this is best used together with Compress PDF's re-save step, or for visual-only redaction rather than forensic-grade removal.
