Vector icons
November 10, 2014 — August 7, 2022
Various libraries of vector icons are available online, either as SVG or as fonts. Here are some:
More complete and widely supported but bloatier: font icons such as fontawesome.
Or: construct a font of just the icons you need. An easy tool for that is Glyphter or Fontello.
You can go both directions between fonts and SVGs via the tool fontforge.
