How much file size do I save by converting JPG to WebP?
According to Google's comparative compression benchmarks, WebP lossy images are 25% to 34% smaller than comparable JPEG images at equivalent Structural Similarity Index (SSIM) perceptual quality scores. Converting JPG to WebP reduces bandwidth usage, accelerates Core Web Vitals (specifically Largest Contentful Paint), and maintains universal compatibility across modern browsers.
Key Takeaways
- WebP files are 25% to 34% smaller than equivalent JPEGs at identical quality.
- Improves Google Core Web Vitals and Largest Contentful Paint (LCP) metrics.
- Supported by over 97% of modern web browsers worldwide.
- Batch convert up to 100 JPGs simultaneously with one-click ZIP packaging.
