Quick answer

AVIF supports transparency and leads in compression efficiency. Converting a transparent PNG to AVIF can significantly reduce file size while preserving the alpha channel. Note that AVIF compatibility is still maturing — a fallback is recommended. Some browsers do not yet support AVIF encoding; this tool will show a clear status in those cases. Conversion happens in your browser with no upload.
