Image Steganography
Hide secret text messages inside ordinary-looking PNG images using LSB encoding.
1. Upload Carrier Image
2. Enter Secret Message
3. Password (optional)
A password XOR-encrypts the message before embedding. The same password is required to decode.
About This Tool
- Upload a PNG image as the carrier
- Type your secret message in the text field
- Optionally set a password for extra security
- Download the encoded image — it looks identical to the original
- To decode: upload the encoded image and click Decode
- Hiding confidential messages in plain sight
- Learning about steganography and data hiding techniques
- CTF (Capture The Flag) security challenges
- Privacy-conscious communication
- Always use PNG format — JPEG compression destroys hidden data
- Larger images can hide longer messages
- The password adds XOR encryption but isn't military-grade security
- The encoded image is visually identical — no one can tell data is hidden
