Why Convert HEIC to AVIF?
Converting from HEIC Image to AVIF Image is useful when you need best-in-class compression (smaller than webp and jpeg). HEIC Image has limitations: limited windows and android support. AVIF Image addresses this by offering best-in-class compression (smaller than webp and jpeg) and royalty-free and open-source. AVIF (AV1 Image File Format) is a next-generation image format based on the royalty-free AV1 video codec.
Xonvert uses professional-grade conversion tools to ensure the highest possible quality when converting HEIC Image to AVIF Image. The output is optimized for the target format's strengths.

About HEIC Image
HEIC (High Efficiency Image Container) is a modern image format based on the HEVC video codec, used by default on Apple devices since iOS 11. HEIC files are roughly half the size of JPEG at the same visual quality, while supporting depth maps, live photos, and image sequences.
Strengths
- ✓ 50% smaller than JPEG at equivalent quality
- ✓ Supports depth maps and live photos
- ✓ Stores image bursts and sequences
- ✓ 10-bit color depth for HDR
Limitations
- • Limited Windows and Android support
- • Not widely supported on the web
- • Patent licensing concerns (HEVC)
- • Many apps require conversion to view
Developed by MPEG (ISO/IEC) (2015)
About AVIF Image
AVIF (AV1 Image File Format) is a next-generation image format based on the royalty-free AV1 video codec. AVIF offers the best compression efficiency of any current image format — up to 50% smaller than WebP and dramatically smaller than JPEG — while supporting HDR, wide color gamut, and transparency.
Strengths
- ✓ Best-in-class compression (smaller than WebP and JPEG)
- ✓ Royalty-free and open-source
- ✓ HDR and wide color gamut support
- ✓ Both lossy and lossless compression
Limitations
- • Slower encoding than JPEG or WebP
- • Growing but not yet universal browser support
- • Complex format requires more CPU to decode
- • Relatively new with limited editor support
