What is a AI file?

An AI file is a drawing created with Adobe Illustrator, a vector graphics editing program. It is composed of paths connected by points rather than bitmap image data. Since AI files are saved in a vector format, they can be enlarged without losing any image quality.

You can also open AI files with other third-party applications, such as ACD Systems Canvas (Windows), CorelDRAW Graphics Suite (Windows and macOS), GIMP (multiplatform), and Inkscape (multiplatform).

NOTE: If you are a Mac user, you can also view AI files with Apple Preview, which is bundled with macOS.
