Permanent Byte-Level Redaction

Permanent Offline-First PDF Text Redacter

Wipe sensitive legal PII forever. Unlike common editors that just place a black box on top, our tool permanently deletes coordinate-level characters to prevent text recovery.

Technical Framework & Principles

Breaking the Limitations of Traditional Cloud Document Tools

Stop risking legal leaks by using black shapes to cover sensitive text in PDFs. Simple annotations are easy to bypass, but our offline redaction tool scrubs content streams securely. By mapping redaction bounding boxes and executing pixel scrubbing, it strips underlying characters flawlessly. It removes vector coordinates, text segments, and raster pixels, leaving the blacked-out zones completely empty. The entire sanitization pipeline runs locally via WebAssembly, providing legal teams and compliance officers a robust, private, hyper-fast redaction workflow.

Frequently Asked Questions

Q:Can redacted text be copied or recovered after processing?

No, text is permanently scrubbed. The system deletes the byte streams and characters inside the bounding boxes, rendering it unrecoverable.

Q:Is there any risk of cloud leaks with my case files?

None. All text stripping, pixel scrubbing, and file exporting run locally in your browser memory. You can run this tool completely offline.

Q:Does it support image redaction?

Yes. Drawing layers inside the selected redaction bounding boxes are permanently rasterized and blacked out to prevent graphical leakages.
