60 free outline icon sets perfect for contemporary designs

With the ever-changing trends, it can be challenging to keep designs relevant and forward-thinking.

No one wants their website or app to look like it’s stuck in the late 1990s (sorry, Comic Sans). Luckily, contemporary design trends favor minimalist, eye-pleasing simplicity in lieu of the flash graphics and bouncing 3D buttons of the past.

A hugely important part of the contemporary “less-is-more” style is the use of icons. Not all icons are created equal, though.

We love the simplicity of outline icons, so we’ve rounded up 60 sets of free outline icons (over 6,500 individual icons) to help you create your best designs yet. Enjoy!
