About this tool
About this tool
JPG to WebP Converter re-encodes JPEG images as WebP using the browser canvas. WebP typically produces noticeably smaller files at equal perceived quality, and the quality control lets you find the right balance. The conversion runs fully client-side.
WebP delivers smaller files than JPEG at similar visual quality, which speeds up websites and saves bandwidth. This tool decodes your JPG and re-encodes it as WebP with a quality slider, all in the browser, so you can ship lighter images without touching a server.
Built for daily work
- Optimize hero images and product photos for faster page loads.
- Reduce image weight before uploading to a CDN or static site.
