What “reviewed” means on this page

Format fit: whether the “what is this file?” description plausibly matches common real-world use of the extension, including category, typical MIME types, and aliases.
Opening paths: whether Windows / macOS / Linux steps read plausibly for current OS dialogs and default apps. Not every step was tested on every OS version.
Security framing: whether risk notes match the extension class (for example executables vs plain data) and whether affiliate wording does not contradict the security section.
Sources and further reading: external links should point to vendors, standards bodies, or other primary references where possible; not every detail is individually sourced.
Limits: this is clarity and safety-messaging QA, not a guarantee that every statement is exhaustive or that every binary you download is harmless. Pages without “Reviewed by” have not been through this editorial pass yet.

What is a .AI file?

.AI stands for Adobe Illustrator Artwork, a proprietary file format developed by Adobe Systems for representing single-page vector-based drawings in either the EPS or PDF formats.

Background

The .AI file format was introduced by Adobe Systems as a native format for Adobe Illustrator, a leading vector graphics editing software. It is widely used by graphic designers and illustrators for creating logos, icons, and complex illustrations due to its ability to maintain high quality at any scale. Unlike raster images, vector graphics in .AI files are composed of paths defined by mathematical expressions, allowing for infinite scalability without loss of resolution. The format is also compatible with other Adobe applications, making it a versatile choice for professionals in the creative industry. Despite being a proprietary format, many other vector graphic software applications have developed compatibility with .AI files, broadening their usability across different platforms.
