How to redact PDF files securely and permanently?
When sending PDF documents containing sensitive information like bank details or ID numbers, standard redaction tools are dangerous. They often just overlay a black vector box, which hackers can easily remove to reveal the hidden text. Our Geek Edition PDF Redaction Tool uses military-grade rasterization. The black boxes you draw are merged with the underlying text into an un-layerable pixel image. It runs 100% locally in your browser memory, ensuring your business secrets are never uploaded and can never be reverse-engineered.
