Converting AVIF to HEIC lets you take advantage of HEIC's approximately 50% smaller than jpeg at equivalent visual quality. AVIF files (AV1 Image File Format) can be converted to HEIC (High Efficiency Image Container) for better compatibility, smaller file sizes, or access to features that AVIF does not support.
AVIF (AV1 Image File Format, introduced in 2019) uses AV1 intra-frame (lossy and lossless) compression. HEIC (High Efficiency Image Container, introduced in 2015) uses HEVC (H.265) intra-frame compression. AVIF browser support: All modern browsers (Chrome 85+, Firefox 93+, Safari 16.4+). HEIC browser support: Limited (Safari only on macOS/iOS).
The quality impact depends on the specific settings used during conversion. HEIC uses compression that may affect quality depending on the chosen settings.
Typical AVIF file size: A 12MP photo at medium quality: ~1-2 MB. Typical HEIC file size: A 12MP iPhone photo: ~1.5-2.5 MB.
For the best conversion results, always start from the highest quality source file available. Converting from a previously compressed file compounds any existing compression artifacts. When in doubt, use higher quality settings — you can always re-convert at lower quality later, but you cannot recover quality that has been lost.
