Adobe Illustrator is a vector graphics editor used for creating logos, illustrations, icons, and other scalable artwork. Unlike raster-based software, Illustrator allows designers to work with paths and curves that can be resized without losing quality. It is a crucial tool for graphic designers working in branding, print media, and web design. Illustrator integrates seamlessly with other Adobe products, offering a comprehensive design suite for professionals. Its rich set of tools for typography, color management, and shape-building makes it the standard for vector-based artwork in the design industry.
