## Answer

Use Deep Clean below to strip Info/XMP metadata, flatten forms, and drop common embeds before you share. For text under black boxes or PII on the page, redact first, then clean, then verify with the privacy checker.

## Limits

- Deep Clean does not destroy visible page text under fake black boxes — use Redact for that.
- Not a forensic wipe of every possible stream.
- Bookmarks and some structures may be dropped.

## FAQ

### What hidden data does Deep Clean remove?

Document properties, XMP author fields, form field values, embedded files, and common catalog extras that often travel with a shared PDF.

### Is removing metadata enough?

No if sensitive text is still on the page or under black boxes. Redact content first, then Deep Clean, then re-check.

### Does this upload my file?

No. Cleaning runs in your browser.
