Icons are visual shorthand, conveying complex concepts in just a few pixels. Used judiciously, they give the reader an instant visual cue, and we find ourselves using them when developing web sites, hacking WordPress themes, and even for a fresh touch in print design.
Mini icons are 16 x 16 pixels or smaller, meaning there's little room for frou-frou if they want to pack a big punch. Rather than fight the small size's limitations by pushing multicolored designs or foisting fancy glosses or shadows upon them, the very best mini icons say it plain — form following function.
These four minimalist mini icon sets are the best of the best, chosen for web and blog utility and ranging in size from 10 x 10 to 16 x 16 pixels. They're either gray or one color, and its simple to modify them to whatever color you like in Photoshop.
