When Should You Use WebP Images?

You should use WebP for almost all web content today.

  • Websites & Landing Pages: To pass Core Web Vitals (LCP) and rank higher on Google.
  • Blogs: To allow articles to load instantly on mobile 4G/5G networks.
  • E-commerce: To display high-definition product images without slowing down the checkout page.

Is WebP Better for Website Speed & SEO?

Yes. Google explicitly recommends WebP in its PageSpeed Insights tool. Because the files are lighter, they download faster, which improves the "Largest Contentful Paint" (LCP) metric—a direct ranking factor for SEO.

Limitations

While WebP is the future, there are minor trade-offs:

  • Old Browsers: Very old versions of Safari (pre-2020) and Internet Explorer do not support WebP.
  • Editing: Not all desktop image editors support WebP natively (though Photoshop now does).
  • Generation Loss: Converting a low-quality JPG to WebP won't magically fix the quality; it only optimizes the file size.
