About this generator
Hiding text in an image is called steganography. This tool first encrypts your message with a password, then writes the encrypted data into the tiniest details of the pixels of a PNG image, where it is invisible to the eye. Send the picture like any other and the receiver loads it into the tool to read the message. Use PNG files and avoid apps that recompress images, because compression destroys the hidden data.

Frequently asked questions
- Why must I keep the image as PNG?
- PNG keeps every pixel exactly. JPEG and many chat apps change pixels, which destroys the hidden data.
- Can someone see that there is hidden text?
- The picture looks normal, but steganography tools can detect it. That is why the message is encrypted first.
- How much text fits in an image?
- It depends on the size of the picture. Larger images hold more, and the tool tells you if the message is too long.
