Transparency kept
Transparent WebP pixels stay transparent in AVIF.

When WebP to AVIF is useful
Some publishing pipelines and CDNs prefer AVIF. Converting creates a new AVIF file from the WebP pixels.
File size can go up or down. Compare the result card before you replace an existing WebP asset.
Quality
The quality slider affects lossy AVIF encoding. A higher value keeps more detail and usually uses more bytes.
For a size limit, use Target Size. The converter measures the encoded AVIF after each attempt.
