Privacy Redact
Privacy Redact is a data redaction library that detects and removes private information locally in text, screenshots, and PDFs.
Privacy Redact is a JavaScript library and set of components designed to detect and redact private data before documents reach an AI or another person. It processes text, images, and PDF files entirely on the local device, ensuring nothing is uploaded or shared with external servers. The software scans for credit cards, national IDs, emails, phone numbers, addresses, API keys, faces, and barcodes, applying redaction methods like blur, pixelate, or blackout. It is built for developers who need to integrate privacy checks into web applications, React frontends, or Node.js backends. Supported formats include PNG, JPG, WebP, GIF, BMP, AVIF, and PDFs, while excluding HEIC files. The tool stands out by flattening PDFs and stripping hidden metadata to prevent data leaks.
