Hide a Message in an Image
Conceal a text message inside an ordinary PNG photo.
Processing on your device…
Your message is encoded into the least significant bits of the image's pixels — invisible to the eye, but recoverable with this same tool.
Frequently asked questions
Does hiding a message change how the image looks?
No visible difference — only the very last bit of each pixel's color changes, far below what the human eye can perceive.
Why must the image be PNG?
JPEG's compression discards exactly the kind of fine pixel detail the hidden message relies on. PNG preserves every bit exactly.
