Answer
Preload is a resource hint that starts fetching a resource needed by the current page earlier. • Use `<link rel="preload">` with the correct `as` value. • The page must still reference and use the resource normally. • Preloading too many files can compete with more important downloads.
💡 Simple Example
<head><link rel="preload" href="/fonts/site.woff2" as="font" type="font/woff2" crossorigin></head>

Preload fetches a known current-page resource early; use it only for important resources.
