Frequently Asked Questions (FAQ)
Will the image look different after hiding text in it?
No. LSB steganography only changes the lowest binary bit in color channels, resulting in color variations of at most 1/255th of a value, which is undetectable by the human eye.
Why is PNG format required for steganography?
JPEG uses lossy compression that alters pixel values and destroys the embedded bits. Lossless PNG preserves every pixel bit exactly.
