Why Convert AVIF to HEIC?
While both are advanced formats with similar compression, HEIC has native support on every Apple device since iOS 11 and macOS High Sierra. AVIF requires third-party apps on iOS and macOS. If you’re working with Apple devices and need native format support, converting AVIF to HEIC is the way to go.
How to Convert AVIF to HEIC
Upload your AVIF file by dragging it into the converter or clicking to browse. Files up to 50 MB are supported.
KoalaPic decodes the AVIF and re-encodes to HEIC using HEVC compression with adjustable quality.
Download the HEIC file. Both files are deleted after 1 hour.
Quality Note
Both use advanced compression derived from video codecs. There is a small generation loss since both formats are lossy, but at quality 80+ the difference is imperceptible. File sizes are comparable between the two formats.
