How to redact a PDF so covered text cannot be recovered
A black rectangle you can delete is not redaction. ChargeBite paints opaque boxes, then rasterizes those pages so the words underneath are gone.

Step-by-step
- Open Redact PDF.
- Drop the file. Pages preview in this browser — nothing is uploaded yet.
- Drag a box over each secret. Switch pages and add more boxes.
- 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.
