Why there's no upload step

WebP has been around years longer than AVIF, so CMS uploaders, e-commerce platforms, and messaging apps that reject AVIF usually take WebP happily — and you keep most of the small-file benefit instead of ballooning to PNG or JPG. Decoding and re-encoding run entirely in your browser.

Questions
Is my file uploaded anywhere?+

No — everything runs on your device.

Is transparency preserved?+

Yes — WebP supports alpha transparency just like AVIF.

How do the file sizes compare?+

WebP output is typically a bit larger than the AVIF original (AVIF is the newer, more efficient codec) but still far smaller than PNG or JPG.

When should I use PNG instead?+

When the destination is an old app or a form that only whitelists classic formats — see AVIF to PNG or AVIF to JPG.
