What is LSB steganography?

It is the substitution of the least significant bit of the image's color bytes with bits of the secret message. Because the change is minuscule, the human eye cannot spot any difference.

Why use PNG instead of JPG?

PNG uses lossless compression, keeping the bits intact. JPG uses lossy compression and will destroy the hidden bits.

Is the process secure?

Yes, encryption is performed locally in your browser with AES-GCM symmetric cryptography before injection.
