Technical Details
Codec Conversion Process
Converts from HEIC’s HEVC (H.265) compression to AVIF’s AV1 codec, leveraging advanced inter-frame prediction and transform coding techniques. The process maintains perceptual quality while achieving superior compression ratios through modern encoding algorithms.
Color Space Preservation
Maintains original color profiles during conversion, supporting Wide Color Gamut (P3) and HDR content from iPhone cameras. Handles 10-bit and 12-bit color depths with proper tone mapping to ensure accurate color reproduction in the AVIF output.
Container Format Migration
Extracts image data from HEIF container structure and repackages into AVIF’s streamlined container format. Preserves essential metadata while optimizing file structure for web delivery and streaming applications.

Frequently Asked Questions
Will converting HEIC to AVIF reduce image quality?
AVIF typically provides better compression efficiency than HEIC, meaning you can achieve the same visual quality at smaller file sizes, or better quality at equivalent sizes. Both formats use advanced compression, but AVIF’s AV1 codec is generally more efficient than HEIC’s HEVC codec.
Can I convert iPhone Live Photos stored as HEIC files?
Yes, Convertify can extract and convert the still image portion of Live Photos from HEIC format to AVIF. However, the motion component will not be preserved as AVIF is a still image format, not a container for multiple frames.
Which browsers support AVIF images after conversion?
AVIF is supported by Chrome 85+, Firefox 93+, and Edge 121+. Safari has partial support starting with version 16. This covers the majority of modern web browsers, making AVIF more web-compatible than HEIC format.
Are camera settings and location data preserved during conversion?
Convertify preserves essential EXIF metadata including camera settings, timestamps, and GPS coordinates when converting from HEIC to AVIF. However, some Apple-specific metadata may not transfer due to format differences.
How much smaller are AVIF files compared to the original HEIC?
AVIF files are typically 20-30% smaller than equivalent HEIC files at the same quality level due to the superior compression efficiency of the AV1 codec. Actual savings depend on image content and compression settings used.
Can I batch convert hundreds of HEIC photos to AVIF?
Yes, Convertify supports massive batch processing and can handle thousands of HEIC files simultaneously. The offline processing ensures your photos remain private while converting entire photo libraries efficiently.
Will AVIF files work on older devices and software?
AVIF is a newer format with growing but not universal support. Older devices and software may not display AVIF images. Consider your target audience’s devices when choosing between formats, or maintain JPEG versions for maximum compatibility.
Is there any advantage to converting HEIC to AVIF for printing?
For printing purposes, the conversion can be beneficial if your photo editing or printing software doesn’t support HEIC but does support AVIF. However, both formats may need conversion to TIFF or high-quality JPEG for professional printing workflows.
