JPG (or JPEG) is one of the most widely used photo formats on the web, valued for broad compatibility and solid lossy compression. It has been the default format for cameras, smartphones and websites for decades. However, JPG files are often larger than they need to be for modern web use, which slows down page loads and increases bandwidth costs.
WebP is a next-generation image format developed by Google, built specifically to improve web performance. It supports both lossy and lossless compression, and typically produces files 25–35% smaller than JPG at similar visual quality. Because pages load faster with smaller images, WebP has become the recommended format for modern websites, blogs and online stores.
For photography where maximum compatibility with older software matters, JPG remains a safe default. But for anything published on the web — blog posts, product photos, hero banners, social graphics — WebP is almost always the better choice, since it reduces file size significantly while keeping visual quality intact. If your priority is faster load times and better Core Web Vitals, WebP is the format to use.
Converting JPG images to WebP doesn't directly boost search rankings, but it improves several technical signals search engines consider important — page speed, Largest Contentful Paint, and overall Core Web Vitals. Faster-loading pages tend to have lower bounce rates and better user engagement, both of which support long-term SEO performance.
