Converting HEIC to AVIF lets you take advantage of AVIF's best-in-class compression: 50% smaller than jpeg, 20% smaller than webp. HEIC files (High Efficiency Image Container) can be converted to AVIF (AV1 Image File Format) for better compatibility, smaller file sizes, or access to features that HEIC does not support.
HEIC (High Efficiency Image Container, introduced in 2015) uses HEVC (H.265) intra-frame compression. AVIF (AV1 Image File Format, introduced in 2019) uses AV1 intra-frame (lossy and lossless) compression. HEIC browser support: Limited (Safari only on macOS/iOS). AVIF browser support: All modern browsers (Chrome 85+, Firefox 93+, Safari 16.4+).
The quality impact depends on the specific settings used during conversion. AVIF preserves full quality with lossless compression.
Typical HEIC file size: A 12MP iPhone photo: ~1.5-2.5 MB. Typical AVIF file size: A 12MP photo at medium quality: ~1-2 MB.
AVIF encoding is slower than other formats. For dynamic image processing, consider caching converted files. For static assets, the encoding cost is a one-time expense that pays off through permanently smaller file sizes.
