Free online HEIC to MP4 converter

Some video editors, presentation systems, and playback devices accept MP4 but not HEIC, so a HEIC image may need to become a short video. Because HEIC is usually a still image, conversion holds the picture on screen for a chosen duration rather than creating motion.

What HEIC is

HEIC is a file format for images that uses HEIF container technology and commonly stores images encoded with HEVC. Apple devices often create HEIC photos by default; compatible cameras and image software can also open or save them. HEIC files are commonly encountered when transferring photos from an iPhone or iPad to software that does not support the format.

What MP4 is

MP4 is a media container commonly used for video encoded with H.264, as well as audio. H.264 MP4 files play on many computers, phones, editors, and web platforms. Converting a still image to MP4 gives it a playback duration, but does not add motion or sound.

How to convert HEIC to MP4

Online on 101convert.com

1. Upload one or more HEIC files; the page displays the per-file size limit.
2. Set show each picture for to choose how long each picture appears.
3. Start the conversion, then download the resulting MP4 file or files.

Offline with desktop software

FFmpeg is free and runs on Windows, macOS, and Linux. Use a build with HEIC/HEIF decoding support, then run this command to create a five-second, silent H.264 MP4 from one image:

ffmpeg -loop 1 -framerate 30 -i photo.heic -t 5 -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2,format=yuv420p" -c:v libx264 output.mp4

Replace photo.heic with the input filename and change -t 5 to the desired duration in seconds. The filter makes the frame dimensions even for H.264 compatibility.

Adobe Premiere Pro can make a video from a still image when the installed version and operating system can decode HEIC. Import the image with File → Import, place it on a timeline, set its duration, then choose File → Export → Media and select H.264 to create an MP4.

Quality and compatibility

The output is a video frame, not the original HEIC data: motion, depth information, and some image metadata are not carried over as video features. H.264 encoding can reduce image quality; an MP4 also needs a duration, and a static-image conversion does not add audio.
