Image/PDF Personal Information Masking Tool

#Personal Development
A tool that detects personal information candidates in images and PDFs, allows users to confirm each item individually, and then applies redaction or blur.

Main Features

• Human-in-the-loop: Does not automatically confirm OCR or rule detection results; leaves final judgment to the user
• Multiple format support: Compatible with PNG / JPEG / PDF input. Can display and process multi-page PDFs
• In-browser processing: All files are processed within the browser and are not sent to any server
• Multi-faceted detection: OCR via Tesseract.js (supports Japanese and English), regex detection for emails, phone numbers, postal codes, and label-based detection of name and address candidates
• Flexible masking: Choose between redaction or blur. Also supports manual range selection
• Comprehensive review features: Search, filtering by candidate type / status / page, Before / After comparison display
• Safe output: When outputting to PDF, removes the text layer from the original file and reconstructs using only images

Supported Formats

Target Users

• Those who need to digitize and share documents containing personal information
• Those who are uncomfortable with automatic processing and want to perform final confirmation themselves
• Those who do not want to entrust processing of confidential documents to external servers

A fully fictional demo mode (3 pages, 31 candidates) is also included, allowing you to experience the actual operation.
