| Description | .art The .art file format can refer to a few different types of files, but it's most commonly associated with the format used by America Online (AOL) for displaying images online. ART files are compressed images that use a proprietary, lossy compression method optimized for quick loading over slow connections. However, due to its proprietary nature and the decline in AOL's usage, the ART format is not widely supported by other image viewing or editing software. |
| Technical details | The .art file format, less known than formats like .jpg or .png, is associated with various software, notably for images compressed with AOL's Johnson-Grace compression algorithm. This lossy compression was designed for fast downloads over dial-up connections, resulting in small file sizes but potential loss in image quality, especially after repeated saving. .art files have limited compatibility, requiring specific software for proper viewing, and were mainly used for AOL's services like web browsing or email. Scaling up these images can degrade quality, and their ability to store metadata varies with the software used. The .art extension's specifications differ across applications, making handling challenging without knowing the creation context. With declining usage in favor of formats like JPEG and PNG, editing .art files typically requires the original creation software or compatible tools. This format's proprietary nature makes it less prevalent and standardized compared to more universal image formats. |
