JPG to WebP Converter: limits and things worth knowing

• WebP typically produces files 25-35% smaller than JPEG at comparable visual quality, which is why it has become the default web delivery format.
• Re-encoding a JPEG is a second lossy pass, so use a high quality setting. Converting from the original source rather than from an already-compressed JPEG always gives a better result.
• Browser support is universal on current versions, but email clients and desktop software lag badly — do not use WebP in an email.

Is it private and secure?

Your privacy is built in. JPG to WebP Converter does all processing on your own device using client-side code, so your files are never transmitted, stored or seen by anyone — including us.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
