Steganography: Hidden Message

Have you ever wanted to hide a secret message inside a photo? With Steganography, you can encode a message or image in a picture and then save it or send it to a friend. The message can only be decoded using the same app, but if you want to ensure that only the intended receiver can read the message.

Steganography is the best steganographic app available for iOS. Send messages and images without anyone knowing.

Steganography is the practice of hiding data in plain sight. Pictograph works by changing the least significant bits in each pixel in a specific way so that a message can be hidden. Because Pictograph only changes the least significant bits in a pixel, the change is imperceptible to human eyes.
