Frequently asked questions
Is this admissible in court?+
Pixel-level burning meets the highest redaction standards. Consult your legal team for your jurisdiction's specific requirements.
Can I redact multiple regions?+
Run the tool repeatedly, or use the Pro PDF Redactor for multi-region workflows.
What about scanned PDFs?+
Scanned PDFs are essentially images and work directly. For text-based PDFs, the redacted area becomes a raster overlay.
