What is an AI file?

Adobe Illustrator Artwork

Developed By
Adobe Inc.
Initial Release
1987
MIME Type
application/postscript

The Adobe Illustrator Artwork (AI) format is a proprietary vector graphics file type developed by Adobe Systems for representing single-page vector-based drawings in either the EPS (Encapsulated PostScript) or PDF (Portable Document Format) standards. Early versions utilized a simplified PostScript syntax (PGF), while modern versions (version 9 and later) rely on a PDF-compatible structure containing an embedded PGF copy for backward compatibility. The format supports scalable paths, distinct layers, and CMYK color models, making it a standard in the commercial print and digital graphics industry.

How to open an AI file

Opening AI files natively requires Adobe Illustrator. However, files saved with PDF compatibility enabled can be viewed in Adobe Acrobat, Apple Preview (macOS), or standard PDF readers. For editing without Adobe subscriptions, users can utilize vector graphics software such as CorelDRAW, Inkscape (via import), or Affinity Designer. Non-compatible AI files (saved without PDF data) may strictly require Illustrator or specialized conversion tools.

What is a WMF file?

Windows Metafile

Developed By
Microsoft
Initial Release
1990
MIME Type
image/wmf

Windows Metafile (WMF) is a 16-bit graphics file format originally introduced in Windows 3.0 (1990) to store a sequence of Graphics Device Interface (GDI) function calls. Unlike pure bitmaps, WMFs contain instructions for drawing vector lines and circles, though they can also encapsulate raster images. The format suffers from device-dependence and lacks the color handling capabilities of its 32-bit successor, Enhanced Metafile (EMF), leading to its deprecation in modern development.

How to open a WMF file

Due to its legacy status, WMF is natively supported by the Windows Picture and Fax Viewer and Microsoft Paint. For professional editing and conversion, vector graphics software such as Adobe Illustrator, CorelDRAW, and Inkscape (using UniConvertor) is recommended. On Linux, the libwmf library enables support within the GIMP and ImageMagick suites.
