Convert iPhone MOV videos to MP4 on Windows
A MOV from an iPhone usually already contains H.264 or HEVC video. Converting it to MP4 is mostly a change of container, which means it can be instant and lossless when the codec fits.
Quick answer. Open Video Converter, drop the MOV, choose MP4 with Quality "Same as source" and press Convert. If the video stream fits the MP4 container, it is copied without re-encoding: a 1 GB file converts in seconds with zero quality loss. Otherwise the tool re-encodes on your device. Nothing is uploaded.

Step by step
- Open Video Converter and add the MOV file.
- Choose MP4 and leave Quality on "Same as source".
- Press Convert. Instant means the stream was copied; a progress bar means it is being re-encoded.
- Download the MP4.
Tips that save a second attempt
- HEVC (H.265) MOVs from newer iPhones play in Chrome and Edge but not in every app; if a colleague cannot play the MP4, convert again with Quality "High", which re-encodes to H.264.
- Need the audio only, for a voice note or a reel soundtrack? Choose Audio · M4A.
- Large files? Convert on a laptop; phones work but take longer.
Frequently asked questions
Is anything lost when the stream is copied?
No. Stream copy moves the same video and audio data into a new container; it is bit-for-bit identical.
Why did my conversion re-encode instead of copying?
The source codec was not MP4-compatible (for example ProRes) or you chose a different quality. Re-encoding keeps the picture but takes longer.
Is the video uploaded?
No. Everything runs in your browser on your own device.
