Phosphor Icons review
A strong open-source choice for teams that need six weights and multiple implementation paths.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Phosphor Icons is an open-source icon library for interfaces, diagrams, presentations, and other creative projects. It is suited to design systems and product teams that need one icon family in multiple visual treatments. The documented collection includes 1,248 icons in six weights: Thin, Light, Regular, Bold, Fill, and Duotone. Commercial use is allowed under the MIT License, subject to its license notice requirements.
Its strongest feature is the range of delivery formats and styling options. Raw SVG assets are grouped by weight, while webfont and icon-font usage supports web implementations. React and Vue component libraries, tree-shakable framework packages, and catalog metadata with names, categories, tags, and codepoints give teams several ways to organize and ship the collection. The Figma plugin supports browsing, searching, and copying icons, and integrations also cover Sketch, Penpot, Flutter, Elm, SwiftUI, and Web Components.
Phosphor Icons fits teams that want weight changes to remain available across design and development workflows without adopting a paid plan. The six-weight system is particularly useful when a design system needs distinctions from Thin through Fill or Duotone, while the MIT License supports commercial projects. Its focus is a documented collection of 1,248 icons rather than an unlimited catalog, so projects that need a larger subject range may prefer another library. Choose Phosphor Icons for format flexibility, framework coverage, and consistent weight options; choose an alternative when the collection size or supported workflow does not match the project.
