How do I convert WebP to AVIF?

AVIF can store transparency, so see-through areas in your WebP stay see-through.
Can I convert many WebP files at once?
Yes. Add up to 50 files together, then download them one by one or as a single ZIP.
Is my WebP file uploaded anywhere?
No. Everything runs in your browser on your own device, and your files are never sent to a server. Camera details and GPS location are not carried into the new file.
