Why WOFF for the web

TTF (TrueType) is a desktop font format, great for installing on your machine, but heavier than it needs to be for a website. WOFF (Web Open Font Format) is essentially the same font wrapped in a compressed, web-optimised container: identical glyphs and hinting, typically a good bit smaller, and designed specifically to be served with @font-face. It's the safe, broadly-supported choice for self-hosting a custom font.

Using it with @font-face

Drop the .woff on your server and reference it in CSS:

@font-face {
  font-family: "My Font";
  src: url("myfont.woff2") format("woff2"),
       url("myfont.woff")  format("woff");
  font-display: swap;
}

WOFF or WOFF2?

WOFF2 compresses harder (Brotli) and is smaller, and browser support is now effectively universal. It's the modern default. Listing WOFF after it, as above, gives you a fallback for the rare older client. Either way this is a lossless container change: your glyph outlines and font tables are preserved exactly, so the type renders identically.

TTF to WOFF

This repackages the same glyph outlines from TTF into WOFF. WOFF is a desktop/install font container. The typeface design is unchanged.
