'''Adobe Illustrator Artwork''' (AI) is a proprietary vector graphics format used by the Adobe Illustrator program.

The original format of these files was known as "PGF", but it was later embedded in a [[PDF]] wrapper for compatibility with that format. The format is also related to [[Encapsulated PostScript]] (EPS), and some versions of the file format are made to be compatible with that. Some forms of the file have multiple versions of the data embedded in it for multi-format compatibility.
