About PNG to WebP
WebP was designed for the web: smaller than PNG and JPG at the same visual quality, with transparency. Switching site images from PNG to WebP is one of the easiest page-speed wins.
Is it private?
Yes. PNG 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.

Is transparency kept?
Yes. WebP supports transparency.
Do all browsers support WebP?

No. Everything happens in your browser on your own device. Your PNG files are never uploaded to Nolo or anyone else, and the tool keeps working with the internet switched off.

No sign-up, no daily limit and no file-size cap. Your device's memory is the only limit.
