AVIF vs WEBP
AVIF usually produces the smallest file of any image format at the same quality, especially for photos, but it is slower to encode and slightly less widely supported. WebP is the practical middle ground: small, fast and supported everywhere modern.

Watch out with AVIF
AVIF’s savings are real, but encoding is slow, so a batch that takes seconds as JPG can take minutes as AVIF.
Watch out with WEBP
Images saved from websites arrive as WEBP even when the page looked like it showed a JPG, and then a document editor or upload form refuses them.
