40 best free icon sets, Spring 2015

Whether you’re building a new website, a new app, or a dashboard, you can’t do without great icons.

The Web is in love with icons, they’re used everywhere from apps to responsive sites, all because they pack information into a small space. And because each set of icons is unique, you can give a different voice to a design, just by switching between sets.

Today we’ve put together the best icon sets so far from 2015. Some have been released in the last 4 months, others have had significant updates.

There’s a ton of different themes here, ranging from business, to leisure, and of course plenty of weather icons. There’s also a wide range of types, with some designers favoring flat design, and others reincarnating skeuomorphic design. Some of these icons have been designed by leading names in the field, others are just regular designers who wanted to give something back to the community.

All of the icons here are crystal clear vectors; some are drawn in Photoshop, some in Illustrator, and some in Sketch. All of them are free to download and use in personal or commercial projects.
