Adobe Illustrator is a great tool for designing beautiful, pixel-precise icons. The flexible vector drawing tools give you the freedom to add as much detail as you need and then generate additional sizes quickly and efficiently. Illustrator's multiple-window feature allows you to see your edits in real time. With saved views, you can access any icon on your artboard without having to scroll, and using multiple artboards makes for ease in exporting them for use on your site or in your applications. I hope that this article has given you enough guidance and inspiration to start using Illustrator in your own icon-design workflow.
