Images, fonts, scripts, and videos are the primary components that contribute to page load latency. When users access a site, these assets must be transferred from the server to the browser, and the speed of this process directly impacts user satisfaction, bounce rates, and even search engine rankings. The first and most impactful optimization step is to reduce the physical size of every downloadable asset without sacrificing quality. Image compression tools such as WebP format conversion, lossless compression algorithms, and responsive image delivery (using `srcset` and `picture` elements) can slash file sizes by 50% to 80%. For CSS and JavaScript, minification—removing whitespace, comments, and unnecessary characters—paired with tree-shaking to eliminate dead code, drastically cuts transfer sizes. Additionally, leveraging modern font formats like WOFF2, which offers superior compression over legacy formats, ensures that typography does not become a drag on performance. Server-level compression via Gzip or Brotli further reduces the payload before it ever leaves the server, effectively tripling the perceived speed for the end user. Another critical technique is lazy loading: deferring the download of images and videos that are not immediately visible in the viewport. By implementing the `loading="lazy"` attribute on `` and `
