EPS is a graphics file format based on the Post Script language developed by Adobe. EPS files are self-contained, including fonts, colors, and layout. This makes them ideal for printing, logos, and large-format designs.

Ai is the native file format of Adobe Illustrator, one of the leading tools for vector graphic design. Designers often use Ai files to create logos, illustrations, icons, typography, and other detailed artwork. Like EPS files, AI files are resolution-independent, meaning they can be resized infinitely without losing any pixels.
