Stego Tool (Static GitHub Pages)

A small in-browser steganography utility with a deliberately "old" utilitarian UI.

What it does

• Embeds a file across one or more carrier images using 2 LSBs in RGB bytes (alpha untouched).
• Writes PNG outputs for safety (lossless).
• Extracts from the encoded PNG images back into the original file.
• Optional encryption: AES-GCM with a base64 32-byte key (generated in-app).

Run locally

Just open index.html in a browser.
