Step-by-step

  1. Open Redact PDF.
  2. Drop the file. Pages preview in this browser — nothing is uploaded yet.
  3. Drag a box over each secret. Switch pages and add more boxes.
  4. Redact. Marked pages become 300 DPI images. Unmarked pages stay vectors. Metadata is stripped.

FAQ

Can someone recover the blacked-out text?

Not from the file we return. Marked pages are flattened at 300 DPI with opaque boxes. Unmarked pages keep selectable text.

Is a black highlight enough?

No. Annotations can often be deleted. ChargeBite burns the bars in.
