Pictonigma play online

Pictonigma uses Steganography to hide small files or messages inside of image files without noticeably altering the image appearance. If a password is used, the data will be encrypted. To share the image, a service has to be chosen that does not edit the file. (e.g. WhatsApp will not work, as it compresses the images before sending them)

Two different file formats are supported:
PNG provides more space per pixel and can handle transparent images. JPEG provides less storage space than PNG, but if you use photos the JPEG format would attract less attention.

A compatible PC version can be found at https://grumium.itch.io/pictonigma
