How to Convert HEIC to AVIF: A Complete Guide

HEIC (High Efficiency Image Format) is a modern image format used by Apple devices that offers excellent compression while maintaining high quality. AVIF (AV1 Image File Format) is an even more advanced format that provides superior compression efficiency. Converting HEIC to AVIF can reduce your image file sizes by up to 50% compared to JPEG while maintaining better quality.

Why Convert HEIC to AVIF?

Wide Browser Support: AVIF is supported by all modern browsers including Chrome, Firefox, Safari, and Edge.
Superior Image Quality: AVIF supports 10-bit color depth, HDR, and wider color gamuts than HEIC.
Future-Proof Format: AVIF is based on the AV1 video codec, making it a future-proof choice for web images.
