What is AVIFS?

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.

What is WEBP2?

WebP2 is the next-generation image format from Google, building on the success of WebP with significantly improved compression efficiency. It targets 30% additional size reduction over WebP at equivalent quality.

When Should You Use AVIFS vs WEBP2?

AVIFS vs WEBP2: Key Differences

• •The core technical difference: AVIFS relies on lossy compression whereas WEBP2 uses lossy compression.
• •Since both AVIFS and WEBP2 use lossy compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Transparency: Full alpha channel with improved compression efficiency
• •File sizes: AVIFS files typically range N/A and WEBP2 files 30-50% smaller than JPEG, 15-20% smaller than WebP.
• •Primary audience: AVIFS is built for modern web animations, high-efficiency image sequences scenarios, while WEBP2 focuses on high-efficiency web graphics, next-gen responsive images — pick the format that matches your output requirement.
