FontServer Technology Intelligence

What is FontServer?

FontServer refers to web font hosting and delivery services that provide optimized font files to websites. These services handle font licensing, format conversion, subsetting, and CDN delivery, making it easier for developers to use custom typography without managing font files directly.

Font servers solve several technical challenges: they serve fonts in the optimal format for each browser (WOFF2, WOFF, TTF), subset fonts to include only needed characters, handle licensing compliance, and provide fast global delivery through content delivery networks.

Various font server implementations exist, from commercial services like Adobe Fonts and Fonts.com to self-hosted solutions. Detection of font server technology indicates a website is using an external service for typography rather than self-hosted font files.
