IcoMoon is a great and simple solution for both designers and developers to access, update, and maintain icons. It works for both small and large projects. You can even edit your icons in the icon editor, and export to all different types of formats including .eot, .svg, .ttf, and .woff. In addition, you can live host the icons so when a designer updates the icon, that change automatically reflects on your team's website.

I've been using IcoMoon for years at our startup, and as a front-end developer and UI designer, it's one of my most used tools. IcoMoon offers a ton of prebuilt libraries to choose from, including the popular ones like Google's material design icon pack and FontAwesome. It also lets you add your own icons by simply dragging and dropping them into your project. You can choose the icons you want from each set and export them all into a single font file! It also generates everything for you, so we just replace the old files when adding/removing icons without worrying about harming the existing icons. To top it all off, your icons can be saved to "the cloud" so that you can access them from anywhere. There are also a ton of options when exporting icons, including browser support, embedding fonts in CSS, generating SASS or LESS, customizing baseline/height, and how you want to use the icons in your HTML (<i>, attribute or class).

Icons offer a very lightweight alternative to traditional image files The interface for library creation can be used by a novice. I found a lot of the base features for free.
