Everyone loves vector icon sets. To have a huge collection of icons that are consistent and that look great really helps you out. You can use them for a variety of purposes, such as for websites and apps. If they are vector, then you can bring them into Illustrator, break them apart, and customize them easily. you can also make them as large or as small as you want, and you don’t have to worry about compromising quality. Another great thing about vector icon sets is that the vector files don’t take up a lot of hard drive space, so you can have vast collections of vector icon sets without much worry of taking up too much real estate. below, I have collected a few great vector icons sets that you can download for free to use in your designs.
