Steganography in your browser

Steganography is the art of hiding a message inside something ordinary so its very existence stays secret. This online tool does both halves: it can conceal text inside an image, and it can scan an image to reveal a message someone hid earlier — no software to install and nothing to learn.

Everything runs in the browser using the canvas, so the work happens on your own device. Add a password to encrypt the payload, and the hidden bits become indistinguishable from random noise without the key.

How to use the steganography tool

  1. Pick a mode. Choose Hide message to conceal text, or Extract message to reveal hidden text from an image.
  2. Add your image. Drag, choose, or paste a photo. For hiding, type your secret and an optional password.
  3. Run it. Hide produces a downloadable PNG; Extract reveals the hidden text ready to copy.

Encryption vs concealment

Steganography hides that a message exists; encryption hides what it says. Using both — a password on a hidden message — is the strongest combination: an observer cannot tell there is a message, and even if they did, they could not read it.
