Turn AVIF images into .heif files with HEVC inside, for Apple devices and apps that read HEIF but not AVIF - want the .heic name iPhones use? Pick AVIF to HEIC.
Need a copy for Windows or the web as well? AVIF to JPG opens everywhere.
Strictly speaking, AVIF is a HEIF file with AV1 images inside.
But when apps, cameras and Apple devices say they support HEIF, they almost always mean HEIF with HEVC images - the kind iPhones make.
This converter swaps the AV1 inside for HEVC, so those apps can open it.
| AVIF | HEIF (HEVC) | |
|---|---|---|
| Container | HEIF | HEIF |
| Codec inside | AV1 | HEVC / H.265 |
| Extensions | .avif | .heif, .heic |
| Typical size | Slightly smaller | Similar |
| Native on | Browsers, Android, Windows 11 | iPhone, iPad, Mac, many cameras |

Drop your AVIF files into the box, keep quality 85 or pick a preset, and press Convert to HEIF. More than two files come as a ZIP.

Yes, briefly - browsers cannot write HEIF. Your browser decodes the AVIF, sends one PNG over HTTPS, and our server deletes it the moment you download the result.
Usually not - AVIF compresses about as well or slightly better. The HEIF is for apps and devices that cannot read AVIF.
Yes. Transparent areas stay transparent. Pick Fill background for a solid colour.
iPhone, iPad and Mac open it natively. On Windows install the HEIF and HEVC extensions, or preview it in the HEIC Viewer.
