Why WebP is worth the switch
If you're building a website or optimizing images for the web, WebP is the single biggest improvement you can make. Google developed the format specifically for web use, and it shows — WebP files are typically 25-35% smaller than equivalent JPGs with no visible quality difference.
For a site with 20 images averaging 200KB each as JPG, switching to WebP saves roughly 1-1.5MB per page load. That's a meaningful improvement for mobile users and page speed scores.
Compatibility considerations
All modern browsers support WebP — Chrome, Firefox, Safari, and Edge. The only risk is if your images will be viewed in older desktop apps or very old mobile devices. For web-only use, WebP is safe. For images that might be opened in desktop software, JPG remains the safer choice.
