90 beautiful, useful and free icon sets

Following the previous 20 Gorgeous Icon Sets That You Have To Pay For, here is a massive list of my favourite icon sets that are available for free download.

One can never have enough free icons

Paid premium icons are usually gorgeous, but we can never say enough to a free and beautiful icon set, can we?

Beware that when using some of these icons you have to credit the designer somehow. Also, some of these icons can only be used on non-commercial projects, so be sure to read the terms of use.
