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.
