An Adobe-created vector image has which file extension?

The correct answer is .AI. This file extension is specifically associated with Adobe Illustrator, which is Adobe's primary software for creating vector graphics. An .AI file can store complex graphics that maintain their quality when scaled, making it ideal for illustrations and designs that require resizing without loss of fidelity.

In the context of vector images, .AI files can contain various elements such as shapes, paths, colors, and effects, all of which are editable in Illustrator. Adobe Illustrator is widely used in graphic design, allowing designers to create scalable artwork that can be exported to various formats for different uses, such as print or digital media.

While other file extensions like .SVG (Scalable Vector Graphics), .EPS (Encapsulated PostScript), and .PDF (Portable Document Format) can also support vector graphics, they are not unique to Adobe's suite and may come from different sources or applications. .AI specifically denotes a file created within Adobe’s ecosystem, highlighting its purpose and the capabilities it offers for vector illustration.
