Designers love free icon sets. Having quality icons can help to make a site’s design look complete, and can also help with the usability of the site. Social media icons are some of the most commonly used icons, especially in blog design.

Fortunately, there are a number of free sets of quality social media icons. In this post we’ll feature 40 social media icon sets from various designers. Click on the links to be led to the source where the icons can be downloaded. As always when you are dealing with freebies, check the terms and conditions to be sure that you’re using them in a way that is allowed by the designer.
