Steganography

Select language:

Task name: (used to generate output file names)

Max preview size: x px (clear the fields to impose no limit)

Resize image to times or x px (only specify one value to constrain proportions)

Resize lock to times or x px (specify one value only; key position inside lock would be chosen randomly)

Random key rotation Random key flip Regenerate images

Employ dithering (emulates grayscale, but hardens decryption)

Smoother background (doubles the image resolution)
