WebP

WebP is a modern raster image format developed by Google. It supports lossy and lossless compression, alpha transparency, and animation in one format, and all current major browsers can display it.

Why it matters

Image weight is a large part of most page sizes, so a smaller format directly speeds loading and improves metrics like Largest Contentful Paint. Converting JPEG and PNG files to WebP often cuts their size noticeably, though results depend on the image. Older software and some email clients may not open WebP, so keep an original.

AVIF compresses even more in many cases but is slower to encode.

Example

<picture>
  <source srcset="hero.webp" type="image/webp">
  <img src="hero.jpg" alt="Product dashboard" width="1200" height="600">
</picture>

Browsers that support WebP load it; others fall back to the JPEG.

Common mistakes

• Converting an already heavily compressed JPEG, which adds artifacts without much saving.
• Deleting the original files after conversion.
• Forgetting alt text and dimensions on the img tag.
