Convert OTF to WOFF2.
Convert an OTF font to WOFF2 for the web — smallest size, fastest load, outlines preserved exactly.
OTF on the web means WOFF2
OTF and TTF are both desktop font formats — the main difference is that OTF uses CFF (PostScript) outlines while TTF uses TrueType ones. Browsers don't care which: for the web you want WOFF2, the Brotli-compressed wrapper that loads fastest. Converting your OTF to WOFF2 makes it web-ready and dramatically smaller on the wire.
Using it in CSS
Reference it with @font-face and src: url('font.woff2') format('woff2'), and add font-display: swap so text stays visible while the font downloads. WOFF2 covers essentially all modern browsers.
The font itself is untouched
This only changes the container and compression — the CFF outlines, hinting and every font table come through exactly, so the typeface renders identically, just lighter to load.
