Image Steganography

Encoding & Encryption Open API 65 uses

An online image steganography tool that writes text into the least significant bit (LSB) of PNG/BMP images with virtually no visual change, and reads it back again. Use your own carrier image or auto-generate one; lossless encoding and decoding are done purely in PHP on the server. This is an Open API tool; using it requires signing in or calling it with an API key.
