What true redaction means

Drawing a black rectangle over text hides nothing: the words are still in the file, and anyone can select or search for them. True redaction deletes the underlying content first and then covers the area. This difference has caused real leaks in published legal and government documents.

FAQ

No. The text underneath stays in place and can be copied directly. This is one of the most common ways confidential information leaks.
Because it will never hand you a file that only looks redacted. If the engine that actually deletes the content is not enabled, the tool refuses to run instead of putting your data at risk — and that engine is already enabled here.
