What is AVIF Format?
The next-generation image format for the modern web
AVIF (AV1 Image File Format) is a cutting-edge image format developed by the Alliance for Open Media. It uses the powerful AV1 video codec technology to deliver exceptional image compression while maintaining outstanding visual quality. AVIF typically achieves 50% smaller file sizes compared to JPEG and 20% smaller than WebP, making it the most efficient image format available today.
Major browsers including Chrome, Firefox, Safari, and Edge now support AVIF natively. This widespread adoption makes AVIF an excellent choice for websites looking to improve loading speeds and reduce bandwidth costs. With support for HDR, wide color gamut, and transparency, AVIF is versatile enough for any use case.
