PixelVault – Client-side AES-encrypted steganography in PNG images

Summary: PixelVault is a zero-trust web tool that hides AES-256 encrypted text inside PNG images using LSB steganography. It performs all encryption and embedding locally in the browser without uploading data to any server, ensuring privacy and security.

What it does

PixelVault encrypts text with AES-GCM 256-bit via the Web Crypto API and embeds it into the least significant bits of PNG images using HTML5 Canvas. All processing occurs entirely on the user’s device.

Who it's for

It is designed for privacy-conscious users, developers, and anyone needing to conceal messages securely within images without server involvement.

Why it matters

It eliminates the risk of data exposure by avoiding server uploads, providing a fully client-side, secure steganography solution.
