Redact

Permanently remove sensitive information.

Hide sensitive information for good: draw black boxes or search automatically for ID numbers, tax numbers, phones, emails, IBANs and cards.

How to use it

1. Choose the PDF.
2. Draw boxes or use automatic search.
3. Review the pages and save.

When it helps

• Share a document without exposing other people's personal data.

Limitations

• Pages with boxes are rebuilt as images so the text underneath really disappears; text on those pages is no longer selectable.
• Automatic search may miss unusual formats; always review.

Frequently asked questions

Can someone remove the black box?

No: the content underneath is actually deleted, not just covered.
