How to Redact (Hide Sensitive Info in) a PDF | Bsbshs
Open the tool →Before sharing a document, you often need to hide sensitive details — an account number, an ID, an address. Here's how to redact parts of a PDF so private information isn't visible.
Why redact before sharing
Documents like statements, bills, and ID copies contain data you don't want everyone to see. Redacting covers those parts so you can share the rest safely — for a proof of address, a claim, or a form where only some details are needed.
How to redact a PDF
- Open the Whiteout / cover tool and add your PDF.
- Draw a box over each sensitive detail to cover it.
- Use white to blend with the page or black for a clear redaction mark.
- Download the redacted PDF.
Redact the right way
The safest redaction removes the underlying data, not just hides it visually. Covering the area and saving as a flattened file or image ensures the information is gone, not merely painted over. Always double-check the exported file by trying to select text in the covered area.
Do it privately
You're handling sensitive info, so privacy matters most here. A browser-based tool redacts on your device — the document is never uploaded.

Summary
To redact a PDF, cover each sensitive detail with a box and then flatten or export the page as an image so the hidden data can't be recovered. Do it in your browser and your sensitive document stays private.
