# Optimize web assets

Last updated Apr 24, 2026|Copy as Markdown|[View as Markdown](https://developers.cloudflare.com/use-cases/performance/web-assets/index.md)|[Agent setup](https://developers.cloudflare.com/agent-setup/)

Unoptimized HTML, CSS, and JavaScript increase page weight and slow down rendering. Cloudflare Speed automatically minifies and compresses these assets, while Zaraz loads third-party analytics and marketing tags server-side to avoid blocking page rendering.

## Solutions

### Speed

Improve the performance of your website or web application. [Learn more about Speed](https://developers.cloudflare.com/speed/).

* **Minification** \- Remove whitespace and unnecessary characters from HTML, CSS, and JavaScript automatically
* **Compression** \- Brotli and Gzip compression applied to all text-based assets at the edge
* **Core Web Vitals** \- Improve Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) scores by deferring non-critical scripts and optimizing asset delivery

### Zaraz

Server-side loading of third-party tools to improve performance and privacy. [Learn more about Zaraz](https://developers.cloudflare.com/zaraz/).

* **Third-party optimization** \- Load analytics, marketing tags, and other third-party tools through Cloudflare without blocking page rendering
