Frequently Asked Questions

Is redaction permanent?

Yes. Redacted content is permanently destroyed at the pixel and text level. It cannot be recovered by removing the black boxes or by any forensic tool.

Can I search and redact all instances of a word?

Yes. Use the search function to find all occurrences of a name, number, or phrase and mark them all for redaction at once.

What is the difference between redaction and covering with a black box?

A black box drawn as an annotation can be removed to reveal the text underneath. Redaction permanently deletes the underlying text and image data.
