Below you will find the 6 best icon libraries for your next projects.

Ionicons

ionicons

Premium designed icons for use in web, iOS, Android, and desktop apps. Support for SVG and web font. Completely open-source, MIT licensed and built by the Ionic Framework team.

Bootstrap Icons

Bootstrap icons

For the first time ever, Bootstrap has its own icon library, custom-designed and built for our components and documentation.

Bootstrap Icons are designed to work with Bootstrap components, from form controls to navigation. Bootstrap Icons are SVGs, so they scale quickly and easily and can be styled with CSS. While they’re built for Bootstrap, they’ll work in any project.

They’re open-sourced (MIT), so you’re free to download, use, and extend. Heads up though, they’re in alpha right now and subject to sweeping changes.

Feather Icons

At its core, Feather is a collection of SVG files. This means that you can use Feather icons in all the same ways you can use SVGs (e.g. imgbackground-imageinlineobjectembediframe).
