PII Blackout — 100% Offline, Automated PDF & Image Redaction
Protecting sensitive data shouldn't mean risking your privacy by uploading files to online tools. PII Blackout is a powerful, local-first desktop application that automates the tedious process of finding and masking Personally Identifiable Information (PII) with military-grade security.

Key Features:
Smart Auto-Detection & Redaction
Manually searching for emails, phone numbers, tax IDs, and names is a thing of the past. PII Blackout automatically scans, detects, and blackouts sensitive data points across your documents in one click.

Absolute, Irreversible Security (Image-Level Blackout)
Unlike standard PDF editors that merely place a black shape over editable text (which can easily be copied or uncovered), PII Blackout flattens and bakes the redaction directly into the image surface of the document. The covered data is permanently destroyed and mathematically impossible to recover.

100% Offline & Local Processing
Zero cloud uploads. Zero data leaks. All file processing and AI detection run entirely on your local machine. Your confidential documents, legal contracts, and financial statements never leave your computer, ensuring strict compliance with GDPR, HIPAA, and CCPA.

High-Efficiency Batch Processing
Designed for professionals and businesses. Whether you have 5 documents or 500, you can drag and drop folders to batch-redact files simultaneously, saving you hours of manual labor.

Keep your sensitive data blacked out and your privacy locked down with PII Blackout.
