Optimizing images is crucial for fast page loads and better SEO. This guide covers techniques to streamline image delivery.

Choosing the Right Formats

Use modern formats like WebP or AVIF that offer superior compression.

Fallbacks may be necessary for older browser support.

Using Responsive Images

Set srcset and sizes attributes to load appropriately sized images based on viewport.

Deliver proportionally smaller images to mobile or low bandwidth users.

Implementing Lazy Loading

Defer offscreen images until they become visible to the user.

This reduces initial load time and saves data.

Compressing Images Effectively

Use tools to balance compression levels and visual quality.

Automate compression in build pipelines for consistency.
