Guide
Permanently Redact a PDF
Draw redaction areas over PDF pages, then create a flattened replacement copy whose selected page content is rendered without the covered information.
Redaction
Does redaction guarantee forensic erasure?
Redaction attempts to remove covered text and warns when it cannot. Always inspect the exported copy; this is not a forensic erasure guarantee.
Does this preserve selectable text?
No. The safe fallback deliberately flattens processed pages, which removes searchable text and interactive structures.
- Flattening removes searchable text, links, forms, and accessibility structure from processed pages.
Can the tool find every secret automatically?
No. Manual review is required and surrounding context may still reveal information.
- Only areas selected by the user are removed.
- The original and any earlier copies remain unchanged and must still be protected.
