Icons8 offers a large collection of icons in multiple styles, along with illustrations, photos, and music. Icons can be downloaded in various formats and sizes, and the site provides plugins for Figma, Sketch, Adobe XD, and other design tools. There are also tools for background removal, image upscaling, and face generation. The free tier requires a link back to Icons8, while paid plans remove that requirement.

UI designers often use Icons8 when they need consistent icon sets across a project. The styles range from outlined and filled to hand-drawn and 3D, which makes it easier to match a visual direction. For developers who need placeholder assets or production icons without designing them from scratch, it's a practical resource.
