Why the WebP Format Matters
Serving images in next-gen formats like WebP is a direct recommendation from Google PageSpeed Insights. WebP provides superior compression, allowing you to serve smaller file sizes without sacrificing visual quality. This is the easiest technical SEO win for most websites.
Optimal Image Formatting
WebP is universally supported by all modern browsers (Chrome, Safari, Edge, Firefox). It combines the best features of both JPEG (lossy compression) and PNG (transparency support) into a single, highly efficient format.
Quick rules:
- Replace heavy PNGs. PNG files are notoriously large because they use lossless compression. Converting them to WebP can often reduce the size by 70% while keeping the transparent background.
- Use for all standard web images. Thumbnails, hero images, and blog photos should all be served as WebP.
- Keep originals for print. WebP is strictly a web delivery format. Do not use it if the user needs to download the image for professional printing.
