Fake vs True Redaction Explained

Basic PDF editors simply draw black rectangles on top of text, leaving the underlying words selectable and copyable. PDFBolt flattens the redacted regions onto a physical pixel canvas, permanently destroying character data from the exported PDF.

Client-Side Performance & Privacy

Permanently Redact Sensitive Data from PDF executes 100% inside your local browser memory sandbox using WebAssembly. Your files are never transmitted across the network or stored on external servers. For multi-gigabyte or heavily nested files, splitting into smaller sections ensures instant responsiveness on low-memory mobile devices.

Frequently Asked Questions

Can someone inspect the PDF source code to see redacted text?
