What is a .AI file? (How to open & convert)
Learn what .AI is, how to open it, and use an embedded local-only tool for common tasks.
.AI AI is a proprietary file format developed by Adobe for representing single-page vector-based drawings in either the EPS or PDF formats. It is the gold standard for logos and professional illustrations. Because it's a professional format, non-designers often struggle to view these files without paying for expensive software.
Basic info
- Full name: Adobe Illustrator Artwork
- Developer: Adobe Inc.
- Category: Design / Vector Image
How to open a .AI file
On macOS: Adobe Illustrator or Apple's 'Preview' app (if PDF compatibility is enabled).
On Windows: Requires Adobe Illustrator or CorelDRAW. However, if the file was saved with 'PDF Compatibility,' it can be viewed by browsers or our local tool.
On mobile: Very limited support. Usually requires Adobe's cloud-based viewers to see layers and vector paths.
