FAQ

Is the redacted content actually removed, or just covered visually?

Actually removed — the page is flattened so there's no way to select, copy, or reveal the text underneath, unlike drawing a black box in a PDF viewer.

Can this be undone once I download the file?

No — redaction is permanent on the output file, which is the point. Keep your original if you need the unredacted version later.

Does redaction affect the rest of the page's content?

No, only the areas you mark.
