How Image Steganography Works:

LSB (Least Significant Bit): Hides data in the least significant bits of image pixels. Changes are invisible to the human eye.
Security: Optional AES-256 encryption adds an extra layer of protection to your hidden messages.
Capacity: Depends on image size and bit depth. Larger images can hide more data.
Privacy: All processing happens in your browser - images never leave your device.

What is Image Steganography?

Image Steganography is the practice of hiding secret messages within digital images. Using the LSB (Least Significant Bit) technique, data is embedded in the image pixels in a way that's invisible to the human eye, allowing covert communication.
