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 CR2?

Canon Raw v2 (CR2) is Canon's second-generation raw image format used by Canon EOS digital cameras for professional photography.

When Should You Use AVIFS vs CR2?

AVIFS vs CR2: Key Differences

• •The core technical difference: AVIFS relies on lossy compression whereas CR2 uses lossless compression.
• •Converting from AVIFS to CR2 changes compression type: lossless source becomes larger but with full quality preservation.
• •How transparency is handled: CR2 supports transparency, so alpha information is preserved during conversion.
• •CR2 files tend to be differently sized than AVIFS
• •Use case fit: AVIFS targets modern web animations, high-efficiency image sequences and CR2 targets canon photography, professional raw editing — your choice depends on which workflow stage you are serving.
