Hide your secretsin pixels

Inject an invisible hidden message into an image. Only insiders will be able to extract it. 100% undetectable, 100% private.

Suggested format: PNG for maximum discretion

Pixel changes are undetectable to the naked eye. The image looks identical to the original.

Everything runs locally in your browser. Your message and image are never sent to our servers.

Use PNG so compression does not destroy your secret (unlike JPEG).

Send the picture like any normal photo (chat, email, social). On screen, nothing betrays the hidden payload.

Without this extractor, the text stays invisible — only someone who runs “Extract message” can reveal it.

The secret is woven into the least significant color bits: a change the human eye cannot perceive.
