Is AVIF really smaller than WEBP?

For most photographic images AVIF compresses a bit better than WEBP at matching quality. For simple graphics the difference is smaller, and WEBP can occasionally win.

Will transparency be kept?

Yes. AVIF supports a full alpha channel, so transparent WEBP images stay transparent after conversion.

Are my files uploaded to a server?
