LSB IMAGE ENCODER
Hide Secret Messages in Images
What is LSB Steganography?
LSB (Least Significant Bit) steganography hides secret messages within images by modifying the least significant bits of pixel color values. These tiny changes are invisible to the human eye but can store substantial amounts of hidden data.
🔒 Invisible Encoding
Messages hidden in LSBs are completely invisible to the naked eye

Pro Tips
- Use PNG format: JPEG compression destroys LSB data. Always use PNG!
- Larger is better: Bigger images have more capacity for longer messages.
- Complex images work best: Photos with lots of detail hide changes better than solid colors.
- Multi-channel encoding: Hide different messages in different channels for puzzles!
- Test your encoding: Use the LSB Decoder to verify your message.
- Preserve quality: Don't resize or compress encoded images - it destroys the hidden data.
