Unless you're a graphic designer by profession or seriously dabbles in graphic design, chances are, you’ve never had the need to learn more about image formats. But if you're starting to explore this world, the vast selection of the said formats can be pretty overwhelming. Thankfully, there's a method to this madness.

The most popular image formats - JPGs, GIFs, and PNGs - are raster images. Every picture found online or in print falls under this category.
