Frequently Asked Questions
- What makes this "true" redaction?
- Text characters and image data in the redacted areas are removed from the PDF's content stream — not just covered with a black box. The underlying data is permanently destroyed.
- Can I redact text by searching for it?
- Yes — use "Find & Redact" to search for text, SSN patterns, email addresses, or custom patterns. All matching instances are highlighted for redaction.
- Is this reversible?
- No. Redaction is permanent and irreversible. A two-step workflow (mark → confirm) prevents accidental redaction.
- Can metadata also be removed?
- Yes — the "Full Metadata Strip" option removes XMP metadata, document info, and embedded file attachments.
