About JPG to WebP
WebP uses better prediction and entropy coding than JPEG. It is supported by all modern browsers, which makes it a good default for website photos.
Is it private?
Yes. JPG to WebP runs entirely in your web browser using your device's own processor. Your files are never uploaded to Nolo or anyone else, and the page cannot send them anywhere: its security policy only allows it to talk to nolotools.com, which has no place to receive files. Results are kept encrypted on your device for 60 minutes in Your files, then deleted automatically, or straight away with Delete all. How Nolo works.
