How to convert MOV to MP4
- Add your .MOV file - drop it in the box above or click to browse.
- Convert it to .MP4 in a few seconds.
- Download your new .MP4 file.
What to expect
- If the
.movcontains PCM (uncompressed) audio, useffmpeg -i input.mov -c:v copy -c:a aac output.mp4to avoid silent or missing audio in the output. - MOV files shot in Apple ProRes must be re-encoded to H.264 or H.265 - re-encoding takes longer and reduces quality compared to a lossless remux.
- HEVC (H.265) iPhone footage remuxes to
.mp4without quality loss, but playback on older Windows PCs may require installing the HEVC Video Extensions from the Microsoft Store.
Frequently asked questions
Does converting MOV to MP4 reduce quality?
Not if the video is remuxed rather than re-encoded. When the
.mov contains H.264 or H.265 video with AAC audio, tools like ffmpeg with -c copy repackage the streams without touching a single frame.Why is my MOV silent after converting to MP4?
The audio track is likely PCM (uncompressed), which most MP4 players do not support. Re-convert using
ffmpeg -i input.mov -c:v copy -c:a aac output.mp4 to transcode only the audio to AAC.Will the file size change?
A lossless remux produces a file of almost identical size. Re-encoding with HandBrake or similar tools typically results in a smaller file, depending on the quality settings chosen.
Can I convert MOV to MP4 on iPhone?
Yes - iMovie on iOS can export
.mov clips as .mp4. For bulk conversion, a desktop tool is more practical.Programs that convert MOV: MyVideoConverter · Miro Video Converter · Nero Multimedia Suite · Aimersoft DRM Media Converter for Windows · Apple TV Video Converter · AviDemux · ConvertXtoDVD · DVD Ripper+Video Converter Ultimate
