Complete Technical Overview & Guide for Sensitive Data & Face Masker

PixelDocs Sensitive Data Masker provides a fast, secure way to redact and blur private information in screenshots and photos before sharing. Pixelate faces, black out credit card numbers, and obscure personal data directly in your browser without uploading images to cloud servers.

Detailed Overview

Sharing screenshots of receipts, software interfaces, ID cards, or legal papers often risks leaking private phone numbers, home addresses, or financial credentials. PixelDocs Sensitive Data Masker provides an interactive canvas brush and rectangle selection tool to apply Gaussian blur, heavy pixelation, or solid blackout boxes over sensitive image regions locally.

Why Use PixelDocs Sensitive Data & Face Masker?

Uploading sensitive screenshots containing passwords or personal identification to cloud redaction tools creates severe data privacy risks. PixelDocs redacts data 100% client-side in browser RAM.

  • Gaussian blur, pixelate, and blackout styles
  • Interactive box drag handles
