Redaction

Redaction removes content for good: when you save, it isn’t hidden under a box, it’s gone from the file.

1. Open the Protect tab.
2. Mark what to remove:
   • Mark for redaction, then drag over each area. The tool stays selected so you can mark several areas.
   • Or Search & redact: type a word or phrase in the sidebar search, then choose Redact all N matches.
3. Review the marked areas. Delete a mark with Delete if you change your mind.
4. Save. Redactions are applied permanently when you save.

What happens when you save

Marked areas are filled (black unless you chose another fill color), and pages that contain redactions are flattened to images (at 200 DPI, or the resolution you chose under Save as → Reduce file size), so everything under the marked areas (text, images, vector graphics) is removed. The remaining text on those pages is put back as an invisible, searchable layer, so you can still search and select it.

Caution

• Keep the original if you might need it: redaction can’t be undone in the saved file.
• Whiteout and Edit existing text don’t remove the original content. Only redaction does.
• Because redacted pages become images, they can look slightly less sharp than the rest of the document.
