What is AVIF?
AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec. It was developed by the Alliance for Open Media and offers significantly better compression efficiency than existing formats like JPEG, PNG, and even WebP. AVIF can reduce file sizes by up to 50% compared to JPEG while maintaining the same visual quality, making it ideal for modern web applications.
