When you develop software, there are plenty of costs beyond icons. And if you buy a large, expensive pack, you’ll rarely use many of the graphics, so it can get pricey. Creating icons yourself is also difficult, even if you’re artistic. It’s hard to avoid shadows, sharp corners, and other small imperfections, so the icon won’t look perfect. With 16×16 Free Toolbar Icons, you can get pixel-perfect 16×16 icons at no cost. 16×16 Free Toolbar Icons are available only in the 16×16 size. There are two color schemes: 256 colors and 32-bit color. Supported formats are PNG, BMP, GIF, and ICO. These free icons are licensed under the Creative Commons Attribution-Share Alike 3.0 License. This means you can use the icons for any personal or commercial purpose (software interfaces, online services, blogs, templates, etc.). However, please include a link to www.aha-soft.com in your credits.
As the name suggests, 16×16 Free Toolbar Icons is a free icon set.
