A legacy video editor or playback device may accept AVI but not HEIC photos. Converting creates a video from each still image; it does not add motion that was not in the original.

What HEIC is

HEIC is a still-image format based on HEIF, commonly used by iPhones and iPads to save photos. Apple devices create it by default when the camera’s “High Efficiency” setting is enabled, and photo-management apps may also export images in this format. Some Windows programs cannot open HEIC without additional support.

What AVI is

AVI is a video container used by older editing programs, media players and playback devices. It can hold video encoded with different codecs, including MPEG-4; compatibility depends on both the AVI container and the codec. AVI may produce larger files than newer video formats, depending on the codec and quality settings.

Start the conversion, then download the AVI file.

Offline with desktop software

On Windows, macOS and Linux, use ImageMagick to decode the HEIC image and FFmpeg to make an AVI. ImageMagick needs HEIC support through its libheif delegate; availability depends on how it was installed. For a single image, run:

Convert the image to PNG: magick input.heic frame.png
Make a five-second AVI at 25 frames per second: ffmpeg -loop 1 -framerate 25 -i frame.png -t 5 -c:v mpeg4 -q:v 5 -pix_fmt yuv420p output.avi

Change input.heic, the duration after -t, or the output filename as needed. The MPEG-4 video codec and yuv420p pixel format are commonly accepted by older players. FFmpeg builds with HEIC/HEIF decoding may also read the original directly, but support varies; converting through PNG avoids that dependency.

Quality and limitations

The result is a video showing a static image for the chosen duration, so it is not equivalent to a motion photo or an animated sequence. AVI does not specify a single codec: a device that supports AVI may still reject a particular video codec. Check the target player’s codec requirements if the file will not open.
