LSB Steganography Details

Least Significant Bit steganography hides data inside the lowermost bits of R,G,B channels. This modification is completely invisible to the human eye.

Lossless PNG is required: Uploading or saving as JPEG/WebP introduces lossy compression artifacts that corrupt the hidden bits, destroying the message permanently.
