About KOSA Icons

KOSA Icons is a library of handmade line icons, drawn one by one to look clean, consistent and to fit variety of interfaces. It started as a little side project when I built just 50 icons that I shared online. Since then, the collection has grown, so I decided to create a new home for them. And that's how this website was born.

• 1,050+ icons in 17 categories.

  From arrows and documents to money, health and weather.

• One consistent style.

  Every icon is drawn on a 16 x 16 grid with the same line weight, so they work together.

• Made to be customized.

  Change the size, color and line thickness right in the library before you copy or download.

• Free to use.

  Personal and commercial projects, no attribution required. See the Licence for the details.

Use them your way

Copy an icon as SVG, download it as SVG or PNG, or download a ZIP. Developers can install the icons as React or Vue components from npm, and AI assistants can search and use them through the KOSA Icons MCP server.

Why handmade?

Each icon is drawn and checked by hand instead of being generated, so shapes, corners and spacing feel right at small sizes. The library keeps growing, with new icons added regularly.

Hi, I'm Katarina, a UI/UX designer and the creator of KOSA Icons.

KOSA Icons is an independent project, designed and maintained by me. The entire library is free to use in both personal and commercial projects under the KOSA Icons licence.

Hope you find the perfect icon for your next project. Enjoy!
