If you manage a website, you know that page load speed is a critical factor for both user experience and SEO. One of the biggest culprits of slow-loading pages is unoptimized images. Enter WebP—a modern image format developed by Google that provides superior lossless and lossy compression.
What is WebP?
WebP is an image format specifically designed for the web. It supports transparency (like PNG) and animation (like GIF) while providing much smaller file sizes than traditional JPEGs and PNGs.
- Lossless WebP images are 26% smaller in size compared to PNGs.
- Lossy WebP images are 25-34% smaller than comparable JPEG images at the equivalent structural similarity (SSIM) quality index.
How WebP Improves Your SEO
Google's Core Web Vitals heavily weigh page load speed. Specifically, the Largest Contentful Paint (LCP) metric is often an image. By serving smaller image files, your LCP score improves, signaling to search engines that your site is fast and user-friendly, which can result in higher rankings.

Best Practices for Web Images
- Use WebP as the primary format: Modern browsers (Chrome, Edge, Firefox, Safari) fully support WebP.
- Lazy Load your images: Only load images as they enter the user's viewport.
- Specify width and height: Always include image dimensions to prevent layout shifts (CLS).
