Material Design Icons

When to use

MDI covers a wide Material-style vocabulary: actions, devices, editors, and domain icons that smaller outline sets miss. Use it when coverage matters more than a single thin stroke. It is not the official Material Symbols font.

When to pick something else

A tighter outline system → Lucide or Tabler. Weight and duotone → Phosphor. Pixel-level Material 3 from Google → use Material Symbols upstream if that pipeline is the requirement. Do not drop one MDI fill into a Lucide toolbar.
