WebP vs JPG: Which Image Format is Best for Websites in 2026?
Detailed benchmark comparison of file size savings, image quality preservation, browser support, and page speed impact between WebP and JPEG.
### What is WebP? WebP is a modern image format developed by Google designed to replace legacy JPEG and PNG formats. It employs advanced predictive coding and lossy/lossless compression algorithms to reduce image file size significantly without visible loss in quality.
Key Benchmark Differences - **File Size**: WebP images are on average 25% to 35% smaller than equivalent JPEG images at identical visual quality. - **Transparency**: JPEG does not support transparency. WebP supports 8-bit alpha channel transparency. - **Animation**: JPEG only supports static images. WebP supports full frame animation (replacing bulky GIFs).
Browser Compatibility Today, over 97% of modern web browsers natively support WebP, including Google Chrome, Apple Safari (iOS & macOS), Mozilla Firefox, Microsoft Edge, and Opera.
Recommendation For web publication, blog posts, e-commerce product catalogs, and landing pages, **WebP should be your primary default image format**. Use 360WebPs to convert existing JPG files to WebP instantly.
