What is PDF redaction — and why it matters
Redaction is the permanent removal of sensitive information from a document before sharing it. True redaction destroys the underlying data — the text is gone from the file entirely. This is different from drawing a black box over text, which only covers the text visually. Anyone can remove a black box overlay and read what's underneath.
