How to Convert Images to WebP for Faster Websites

WebP is the recommended image format for modern websites. Converting your images to WebP can reduce page weight by 25-35%, directly improving load times and SEO rankings.

Why WebP for Websites?

Google has been recommending WebP since 2010, and with good reason. WebP offers significantly better compression than both PNG and JPG. Google's PageSpeed Insights and Lighthouse tools specifically flag opportunities to serve images in next-gen formats like WebP.

Impact on Web Performance

Images typically account for 50-60% of a webpage's total size. Converting from PNG/JPG to WebP can reduce this by a third, which directly improves:

• Core Web Vitals — faster LCP (Largest Contentful Paint)
• SEO rankings — Google factors page speed into search rankings
• User experience — faster loads mean lower bounce rates
• Bandwidth costs — smaller files mean lower hosting bills

How to Convert

Convert your images to WebP format:

• Convert PNG to WebP (lossless graphics)
• Convert JPG to WebP (photographs)

Browser Support

As of 2025, WebP is supported by 97%+ of browsers worldwide, including Chrome, Firefox, Safari, and Edge. For the small percentage of users on older browsers, you can provide fallback images using the HTML <picture> element.
