Both AVIF and HEIF are modern, efficient formats. AVIF is open and royalty‑free, while HEIF is deeply integrated into Apple devices. Use AVIF to HEIF when you need Apple compatibility, or go the other way with HEIF to AVIF.
💡 Pro Tips
- HEIF files on Apple devices usually have the .HEIC extension. Our converter produces compatible HEIC files.
- Both formats support lossless and lossy compression. Choose lossless for archival, lossy for everyday sharing.
- If your AVIF contains HDR metadata, we preserve it in the HEIF output.
- For image sequences (animated AVIF), we convert to HEIF sequence (like Live Photos).
- Convert in batch mode – upload multiple AVIFs and download all HEICs as a ZIP.
- We strip metadata by default for privacy, but you can keep EXIF by toggling the option.
- HEIF supports depth maps from portrait mode; if present in AVIF, they are preserved.
How AVIF to HEIF Conversion Works
AVIF and HEIF are both modern image formats that use advanced video codecs for compression. AVIF is based on AV1, while HEIF typically uses HEVC (H.265). When you convert AVIF to HEIF, our servers decode the AVIF image to raw pixels (preserving HDR and alpha), then re‑encode using the HEVC encoder. The result is a HEIF file that maintains the visual quality and features of the original, now compatible with Apple devices.
The conversion is high‑quality and server‑side. Files are automatically deleted after 10 minutes.
AVIF vs HEIF: Which One to Choose?
AVIF is an open, royalty‑free format with excellent compression, supported by modern browsers. HEIF is the standard on Apple devices and offers similar efficiency, but requires licensing for HEVC.
Choose AVIF for web use and open platforms; choose HEIF when working within the Apple ecosystem or delivering to clients who use Apple products. Our converter lets you move seamlessly between them.
HEIF in the Apple Ecosystem
Since iOS 11, Apple has used HEIF as the default photo format. It saves about 50% space compared to JPG while retaining quality and supporting Live Photos, depth maps, and HDR. Converting AVIF to HEIF allows you to integrate images from other sources into your Apple library without transcoding loss.
