AVIFS files are built around lossy compression. Designed for modern web animations, high-efficiency image sequences, they use the image/avif-sequence MIME type and typically range from varies by content.

When Should You Use PNG vs AVIFS?

Use PNG When...

Reach for PNG when your priority is graphics, logos, images requiring transparency — its uncompromising quality ensures every detail is preserved.

Use AVIFS When...

Reach for AVIFS when your priority is modern web animations, high-efficiency image sequences — its efficient compression makes sharing fast and storage minimal.

PNG vs AVIFS: Key Differences
