Upload a steganographically encoded PNG image to extract and decrypt the classified message stored inside its pixels.
Only lossless PNG images will work. If the image was converted to JPEG or sent through a compression app (like WhatsApp), the data is permanently lost.
Our algorithm scans the raw image data on the HTML5 Canvas, reading the least significant bit (LSB) of each pixel's color channel. It seamlessly reconstructs these invisible bits back into a complete binary sequence.
If the extracted payload contains our encryption signature, the browser's Web Crypto API securely derives your decryption key using PBKDF2. The AES-GCM cipher then mathematically unlocks your original text.
Decryption happens exclusively on your processor. PixelVault is a zero-knowledge architecture; we never see the images you upload, the passwords you type, or the messages you extract.
