PNG, JPG, JPEG, BMP, GIF (max 16MB)

0 / 10000 characters

Remember this key! You'll need it to extract the message later.

🎯 How LSB Steganography Works

  1. Your message is encrypted using XOR cipher
  2. Encrypted data is converted to binary bits
  3. Bits are hidden in the least significant bits of pixel values
  4. Changes are invisible to the human eye
  5. Output is saved as PNG to preserve data

💡 Tips

  • Use strong, memorable encryption keys
  • Larger images can hide more data
  • 3-channel mode is recommended for efficiency
  • Only ASCII characters are supported
  • Always keep the output as PNG format
