What is an .art Image?

edit

The .art file format is a proprietary format used by America Online (AOL) for compressed images. These images were commonly used in the early days of the internet, particularly in the 1990s. The .art format was designed to compress images to a smaller size than other image formats at the time, which made them faster to download over slow internet connections. However, the .art format is not widely used today, and many modern image viewers may not support it.
