Convert Image to WebP Online Free

Convert any JPG, PNG or WEBP image to WebP format instantly — right in your browser. Up to 30% smaller than JPEG at the same quality. No upload, no signup.

Why Use WebP?

WebP is a modern image format developed by Google that uses both lossy and lossless compression. It typically produces files 25–34% smaller than JPEG at equivalent visual quality, and 26% smaller than PNG for lossless images. Smaller images mean faster page loads, lower bandwidth costs, and better Core Web Vitals scores — all of which are direct Google ranking signals.

WebP is now supported by all major browsers — Chrome, Firefox, Safari 14+, Edge, and Opera — covering over 95% of global browser usage. For modern web projects, switching to WebP is one of the easiest performance improvements available without any change to image dimensions or visual quality.

Common Use Cases

Website performance

Serving images as WebP instead of JPEG reduces page weight by 25–34% — a measurable improvement to LCP and page speed scores.

E-commerce product photos

Product image galleries often contain dozens of photos. WebP reduces total page weight significantly, speeding up catalogue pages.

Blog & CMS images

Replace JPEG hero images and inline photos with WebP to reduce bandwidth without touching image dimensions.

Google PageSpeed optimisation

Lighthouse and PageSpeed Insights specifically flag non-WebP images as an opportunity. Converting directly resolves this warning.

CDN bandwidth savings

Serving smaller WebP files from a CDN reduces egress costs at scale, particularly for image-heavy sites with global traffic.

Progressive web apps

PWAs targeting mobile users benefit most from WebP — smaller files load faster on 4G and 5G connections.
