About this tool

ToolAdda's Image Steganography tool lets you embed secret text or files inside PNG images using LSB embedding with AES-256-GCM password encryption, plus built-in steganalysis and bit-plane analysis. Everything runs locally in your browser, so your images, messages, and passwords are never uploaded. It's a free, privacy-focused utility for watermarking, casual private notes, and learning how steganography works.
