The set contains 117 free mini pixel icons in two sizes, 20x20px and 16x16px. The format is .png. Each icon is less than 1KB in size.
I’ve done small icons before, usually 20×20, but this is my first go at a 16×16 set. Some of these, like the speakers, film strip, and web cam icons, are dark, and won’t work well on a black background, but the majority of this set should do just fine.
