How to convert JPG to WebP

Why convert JPG to WebP?
WebP is typically 25–35% smaller than JPG at similar quality, so pages load faster and score better for SEO — a real advantage for online stores. One caveat: some older software and marketplaces still reject WebP. For those, convert them back to JPG with the WebP to JPG converter or keep your original JPG. Want to shrink files even further? Use the free image compressor.
