About PNG
PNG is lossless and universal, but for photographic content it's several times larger than it needs to be. Great for editing masters; overkill for shipping to a live site.
About AVIF
AVIF is a newer image format based on the AV1 video codec. It offers the strongest compression of any widely-supported image format today, with alpha transparency and HDR support. Chrome, Firefox, Safari 16+, and Edge all decode it natively.
Why convert PNG to AVIF?
Convert PNG → AVIF when you're publishing to the modern web and want the absolute smallest file at a given quality. Keep PNG when the destination requires lossless (print, further editing) or doesn't support AVIF.
