There’s no such thing as a free lunch! Or is there? Well if you can eat icons there is. Here are 35 fresh, high quality icon sets free for download. There is a vast amount of free icons sets out there and this is a mere sampling of some of the good ones. If you’re planning to use them for a specific application then you may need to hunt around a bit more. Some of the websites dedicated to icons have decent search facilities that can help.
While these are free, always check any usage limitations. For example some may not allow commercial use. Be careful of attribution if required, and also that you’re getting the set from an appropriate source.
