About Image Steganography (Hide Text in Images)

Steganography is the art of concealing a message within another ordinary file so that the very existence of the message is hidden. In LSB steganography, the least significant bit of each 8-bit RGB color channel is swapped with secret message bits, creating changes imperceptible to human vision.

Supported Formats

Frequently Asked Questions

PNG uses lossless compression. Lossy formats like JPEG discard and compress pixel values, which destroys the embedded secret bits in the image.
