Why can’t JPEGS be transparent?
In: 1537
Pixel data is usually encoded into a set of “channels”. Monochrome images have only one channel that represents the value of the pixels on a scale of black to white.
Color images have three channels: red, green, and blue which comprise the primary colors, and can represent any color when mixed.
The 4th channel is called the *alpha* channel and it represents transparency on a scale from invisible to totally opaque.
The JPEG image format simply does not have an alpha channel. It only has RGB color channels.
