Convert PNG images to WebP format online — smaller files, same quality
or click to browse · Max 20MB
WebP is a modern image format developed by Google that combines the best of PNG and JPG. It provides superior compression — typically 25-35% smaller than PNG — while preserving lossless quality and transparency support. Smaller images mean faster website loading, better SEO Core Web Vitals scores, lower bandwidth costs on mobile networks, and faster page rendering on slow connections. Modern browsers (Chrome, Firefox, Safari, Edge) all support WebP since 2020, making it the recommended format for any website that wants to optimize image delivery without sacrificing quality.
Common use cases: optimizing logos and graphics for WordPress, Shopify, or Wix websites; reducing image weight on e-commerce product galleries; improving Google PageSpeed scores by replacing PNG with WebP; preparing transparent graphics for web banners and headers; reducing storage costs on CDN and cloud services; speeding up mobile sites where bandwidth matters; and modernizing legacy websites built before WebP support became universal.
