MOV to MP4: Convert iPhone Videos Without Losing Quality
Gizke Team · Published · Reading time: 1 minute
Drop the MOV into the video converter, leave MP4 selected and press Convert. For most iPhone and camera videos the result is ready in seconds, because the video and sound are copied into the new file instead of being re-encoded. Nothing is uploaded, so a 2 GB holiday clip doesn't have to travel anywhere.

MOV and MP4 are mostly the same thing
Both are containers: boxes that hold a video stream and an audio stream. An iPhone MOV usually holds H.264 or HEVC video with AAC audio, and MP4 can hold exactly those. Converting is just moving the same streams into a different box. That's why it's fast and why the quality doesn't change.
You'll see "copied without re-encoding" under the output details when that's happening.
When the MP4 still won't play
Since 2017 iPhones record in HEVC (H.265) by default, which Apple explains in its HEIF and HEVC guide. HEVC is efficient, but not every device decodes it:
- Windows needs the HEVC Video Extensions from the Microsoft Store on many PCs.
- Older smart TVs, some video editors and a few upload forms reject it.
Fix it by forcing a real conversion: instead of keeping the original quality, pick a quality level such as High. The converter then re-encodes the video as H.264, which plays practically everywhere. It takes longer, since your computer does the encoding, and the file may come out a little bigger.
Stop the problem at the source
If you keep sending videos to Windows users, switch the iPhone to Settings > Camera > Formats > Most Compatible. New videos are then recorded as H.264 (and photos as JPEG). The files are bigger, roughly 1.5-2 times for the same quality, so it's a trade-off rather than a free win.
While you're converting
The same page can trim the start and end, rotate a sideways clip or remove the sound. If the MP4 is too big to send, Compress Video can bring it down to a target size, and Video to MP3 pulls out just the audio.
