What is WebP — and why does it matter?
WebP is an image format developed by Google and released in 2010. It uses advanced compression algorithms that produce files 25–35% smaller than JPEG and 25% smaller than PNG, while maintaining near-identical visual quality. It supports both lossy and lossless compression, transparency (alpha channel), and even animation.
Google included WebP support in Lighthouse and PageSpeed Insights as a core recommendation, and it is now one of the key factors in the Largest Contentful Paint (LCP) metric — a Core Web Vital that Google uses as a ranking signal.
- Website owners and bloggers. Replacing JPEG hero images with WebP equivalents can shave hundreds of kilobytes per page load, directly improving Google PageSpeed scores.
- E-commerce store owners. Product images are often the largest assets on a page. WebP product photos load faster, reducing bounce rate and improving conversion.
- WordPress site owners. WordPress 5.8+ natively serves WebP images. Converting your existing library is the fastest way to speed up a WordPress site.
- Developers and designers. Including WebP in design handoffs and asset exports helps developers meet performance budgets without extra work on their end.

Privacy by architecture
Your files never leave your browser.
Conversion runs entirely via the browser's built-in Canvas API and WebP encoder. No upload endpoint exists. Your image is converted on your own CPU and downloaded directly.
- No file data transmitted over the network at any point
- No account, sign-in, or email required to use any feature
- Closing the tab clears all data from browser memory completely
- Browser-native WebP encoding — same as Chrome uses internally
