How this tool works

Everything runs inside your browser using the built-in canvas and file APIs. The file you choose is never uploaded to Single Tab Browser or anyone else, there is no queue and no size cap other than your device's memory, and the page keeps working offline once it has loaded.

Frequently asked questions

Is this JPG to WebP tool free?

Yes. It is free, has no file limits beyond what your browser can handle, and needs no account.

Are my images uploaded anywhere?

No. The conversion happens inside your browser using the HTML canvas. Files never leave your device, which is why it also works offline once the page has loaded.
