Frontend Performance: The Complete Guide

Speed Matters

Every 100ms delay in load time can reduce conversions by 7%. Here's how to be fast.

Optimize Assets

• Compress images (use tools like Squoosh)
• Use modern formats (WebP, AVIF)
• Lazy load below-the-fold images
• Minify CSS and JavaScript

Reduce Bundle Size

Code splitting, tree shaking, and dynamic imports keep bundles small.

Critical CSS

Inline critical styles to avoid render-blocking CSS.

Performance is a feature, not an afterthought.
