Frequently Asked Questions

Everything you need to know about DuoIcons.

Q What are DuoIcons?
DuoIcons is a free, open-source collection of duotone (two-tone) SVG icons designed for modern web and mobile applications. Each icon has two layers — a primary and a secondary — giving them depth and personality.
Q Are DuoIcons free to use?
Yes. DuoIcons is 100% free and released under the MIT License. You can use them in personal and commercial projects without any attribution required.
Q Which frameworks are supported?
DuoIcons has native packages for React, Vue 3, Svelte, Tailwind CSS, Alpine.js, Vanilla JS, React Native and Flutter. Every package is tree-shakeable and ships TypeScript types.
Q Can I request new designs for the DuoIcons duotone icons collection?
Absolutely! We are constantly expanding our library of free duotone icons in SVG. If you need a specific symbol that isn't currently in our duotone icons set, you can submit a request through our Community Form. We prioritize the most requested icons to ensure DuoIcons remains the go-to resource for high-quality, customizable duotone icons for modern UI projects.
Q How do I install DuoIcons for React?
Run `npm install @duo-icons/react` in your project. Then import the icon you need: `import { AlignBottom } from '@duo-icons/react'` and use it as a component.
Q Can I customize the icon colors and sizes?
Absolutely. Every icon inherits its color from the CSS `color` property via `currentColor`. You can also pass explicit `color` and `size` props in framework packages, or use CSS variables to theme both layers independently.
Q How do I contribute or request new icons?
Open an issue or pull request on our GitHub repository. You can also click the '+' button on this page to suggest a specific icon. Priority requests can be fast-tracked via a small Ko-fi donation.
Q What is the difference between SVG and Symbol SVG?
A regular SVG is a standalone file you can embed directly. A Symbol SVG wraps the icon in a `` element for use in an SVG sprite sheet, which is ideal for performance-critical applications that reuse the same icon many times.
