JPG to WebP — Free Online Converter, No Upload

Your JPG files stay private — nothing uploaded

Most online JPG-to-WebP converters upload your files to a remote server before returning the result. Ours works differently: all processing runs directly in your browser using built-in Web APIs. No file ever leaves your device — you get a fast, high-quality conversion with complete privacy.
