How It Works
LSB (Least Significant Bit) Encoding

This tool uses LSB steganography to hide messages in images. Each pixel's color values (RGB) are modified slightly by changing the least significant bit. These tiny changes are invisible to the human eye but can store binary data.

Encoding

Your message is converted to binary and embedded into the image pixels.

Decoding

The hidden bits are extracted and converted back to readable text.

Tips
  • Use PNG format - JPEG compression can destroy hidden data
  • Larger images = more capacity - More pixels means more storage
  • Use a password - Adds XOR encryption for extra security
  • Don't edit the output image - Resizing or filtering will corrupt the hidden data
  • Compatible with other tools - Works with stylesuxx and similar LSB tools
