What is WebP?
WebP is an image format developed by Google, publicly released in 2010. It uses a combination of predictive coding (from VP8 video) and lossless encoding techniques to achieve significantly smaller file sizes than JPEG and PNG — roughly 25–34% smaller than JPEG at equivalent visual quality, and 26% smaller than PNG for lossless images.
WebP supports both lossy and lossless modes, transparency (alpha channel), and animation. It is now supported by all major modern browsers (Chrome, Firefox, Safari 14+, Edge). For new projects targeting modern browsers, WebP is the default choice for most web images.
Common Use Cases
Page speed optimization
Replace JPEG and PNG images with WebP to reduce page weight and improve Core Web Vitals (LCP).
E-commerce product images
Convert product photo galleries to WebP to significantly reduce bandwidth and load times.
Blog and CMS images
Convert upload images to WebP before storing them, so all served images are automatically smaller.
Mobile-first sites
Serve WebP to reduce data usage on mobile networks, where image size has the greatest user impact.
Reducing CDN storage costs
Storing WebP images on CDN or cloud storage costs less than equivalent JPEGs due to smaller file sizes.
Format compatibility testing
Convert a small batch of images to WebP to measure actual savings before automating the entire pipeline.
