PDF blur isn’t redaction. Permanent blackout is.
Sharing a PDF with emails, account numbers, or secrets still visible is a liability. Soft blur and overlay “redactions” can often be undone. DocBurn burns solid black into the page pixels — offline, in your browser.
DocBurn — try free, then unlock lifetime for $2.99
Permanent PDF redaction. No upload.
The problem
People send contracts, invoices, and support dumps with PII still in the file. Highlight yellow “redactions,” white boxes, or blur layers look safe until someone copies the text underneath or peels the overlay. Cloud redact tools ask you to upload the same sensitive PDF you were trying to protect.
What DocBurn does
- Draw solid black redactions over text and regions on PDF pages
- Burns redaction into page pixels so secrets can’t be copied or layered away
- Client-side only — nothing uploads
- Sibling to BlotOut (screenshots) for documents
- $2.99 lifetime unlock
Who it’s for
Support teams, freelancers sharing client docs, legal-adjacent workflows, and anyone who needs to share a PDF without leaking the underlying text.
Vs PDF redact — why black-box overlays leave selectable text underneath.
