FluentUI System Icon Browser

Microsoft's FluentUI System Icons library is one of the most comprehensive and polished open-source icon sets available. Used throughout Windows, Microsoft 365, Teams, and Microsoft's web products, these icons are professionally designed, available in multiple styles and sizes, and free to use under the MIT license. The catch is that browsing and exporting them directly from GitHub is tedious, and you have to navigate folder by folder, open raw SVG files one at a time, and download them manually.

The FluentUI System Icon Browser solves that. It loads the entire library at startup and gives you a fast, searchable, filterable desktop interface for finding exactly the icons you need and exporting them in bulk.

Key Features

• Full library coverage — every icon across all styles and sizes, loaded directly from GitHub.
• Instant search — type any part of an icon name to filter the list in real time.
• Style and size filters — narrow by style (Regular, Filled, Color, Light) and SVG size (16, 20, 24, 28, 32, 48 px) independently.
• List and grid views — work in a searchable list or switch to the visual grid to browse by appearance.
• Bulk selection — select individual icons or use Select All to grab everything currently visible.
• Show Selected Only — hide unselected icons so you can review your picks before exporting.
• Persistent selections — your selections are saved automatically and restored the next time you open the app.
• SVG and PNG export — export selected icons as vector SVG files or rasterized PNG at any size you choose.

Who It's For

The FluentUI System Icon Browser is built for anyone who works with FluentUI icons regularly:

• Developers building Windows apps, web apps, or Office add-ins who need icons that match the Microsoft design language.
• Designers building prototypes or UI mockups using the same icon set used across Microsoft 365.
• Power users who want a quick local reference for the library without needing to dig through GitHub.

It runs on Windows 10 and Windows 11 and requires no installation of .NET.
