PlainBytes Redactor is a local-first PDF redaction tool for Windows, built for legal, finance, audit, and compliance workflows. It detects, reviews, and physically redacts sensitive content from PDF documents entirely on your device — no cloud upload, no internet connection required, and no data ever leaves your machine.
Unlike online redaction tools that require uploading confidential documents to third-party servers, PlainBytes Redactor processes everything locally. It includes 145+ built-in detection rules for common sensitive data patterns such as names, ID numbers, financial figures, and contact information, and uses on-device AI to assist with detection and review.
A free trial is available with no registration required.
