Why Optimize Fonts?

Fonts play a crucial role in website design but often come with a performance cost. Large font files can delay page load times, negatively impacting user experience and SEO rankings. Optimizing fonts ensures that only necessary characters and styles are loaded, significantly improving website speed.

Benefits of Font Optimization

✅ Faster page loads by reducing font file size
✅ Improved Core Web Vitals and SEO performance

✅ Better user experience across devices
✅ More control over typography delivery

How Does Font Optimization Work?

Font optimization involves removing unused characters and styles, creating subsets tailored to your site's actual text content. Tools analyze your font files and your website’s text, then generate a smaller font file that includes only the required glyphs. This reduces file size while maintaining the desired typography.
