JPG vs WebP: what changes
WebP typically produces files around 25–30% smaller than JPG at the same visual quality, which is why it's the go-to format for speeding up websites and improving Core Web Vitals. It's supported by every current browser. Keep a JPG copy too if you also need to upload the image to a form or service that hasn't adopted WebP yet.
Other conversions
Your JPG files are converted entirely on your device and never uploaded to a server.
