## 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.

## Limits

- 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.

## FAQ

### 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.
