Short answer
Draw boxes over sensitive areas in the tool below, apply redaction, and download. Pages with boxes are rebuilt as images with the black areas burned in — the text underneath is removed, not just covered. Then check the file (or run the leak check) before sharing.

Files never leave your device

- Redacted pages become images — text on those pages is no longer selectable.
- Automatic PII detection is a separate tool and only covers common patterns.
- Metadata and attachments need Remove metadata or Deep Clean separately.
Frequently asked questions
Is drawing a black box enough to redact?
No. A shape on top leaves the text in the file. This tool rebuilds redacted pages so the text is destroyed.Does redact PDF upload my document?
No. Redaction runs in your browser.How do I check that redaction worked?
Open the download, try to select and search for the blacked-out text, or use the PDF leak check for text still under black boxes.
