About This Tool

The art of hidden writing. Our Steganography tool allows you to embed secret text messages directly into the pixels of an image. The message is invisible to the naked eye and can only be retrieved using our decoder.

Use Cases

Private Messaging

Share sensitive info in plain sight on social media or forums.

Digital Signatures

Hide ownership data deep within the image pixels.

Creative puzzles

Create "hidden clue" games for your audience or friends.

Frequently Asked Questions

Will people see the message?

No, we use Least Significant Bit (LSB) manipulation, which changes pixel colors so slightly that it's invisible to humans.

Does it work with JPEGs?

No, JPEG compression destroys the hidden data. Use PNG or BMP for best results.

Is it encrypted?

The data is hidden, but not encrypted. For maximum security, encrypt your text before encoding it into the image.
