Is Visual Redaction private by default?

All processing happens locally in your browser. No document data is uploaded. The redaction canvas renders pages using PDF.js, the same library used by Firefox.

What this does not protect

  • Redaction is irreversible by design. There is no undo after burning. The original text under redacted areas is destroyed, not hidden.
  • Output file size increases significantly because every page becomes a raster image. Expect 0.5-1.5MB per page at 200 DPI.
  • Text in the output PDF is not selectable. If recipients need searchable text, they would need to OCR the result.
  • Documents over 200 pages are capped for browser memory safety. Split first, then redact sections individually.
  • This is visual redaction only. It does not produce PDF redaction annotations compatible with Adobe's redaction workflow.
  • It cannot fix compromised devices, accounts, or unsafe sharing channels.
