Fluent Filled Icons
9,553 icon elementsFluent Filled Icons is Microsoft's massive open source collection of 9,553 solid-style SVG icons. Covering virtually every UI concept imaginable, this MIT-licensed set is one of the largest and most comprehensive free icon libraries in existence.
With 9,553 solid SVG icons, Fluent Filled Icons is not just large. It is one of the most comprehensive icon libraries ever released as open source. Built by Microsoft for the Fluent Design System, this collection covers everything from basic UI controls to specialized industry symbols, accessibility indicators, and platform-specific glyphs.
Scale That Solves Real Problems
Most icon packs leave gaps. You find the perfect arrow icon, but then need a "building with a checkmark" and it does not exist. Fluent Filled Icons rarely has that problem. With nearly 10,000 icons, the chances of finding exactly what you need are remarkably high. That depth saves hours of searching across multiple icon sets or commissioning custom work.

Microsoft Fluent design language with friendly, modern aesthetics
MIT licensed for unrestricted commercial and personal use
