How to Convert iPhone MOV Videos to MP4
iPhone videos are saved as MOV (QuickTime) files that Windows and Android often refuse to play. Convert them in your browser with a lossless remux: MediaStand's MOV to MP4 tool copies the original video and audio streams bit-for-bit into an MP4 container in seconds — no quality loss, no upload, no software install.
You share an iPhone clip and the reply comes back: 'it won't open'. The footage is fine — the .mov container is the problem. Most iPhone MOVs already hold H.264 or HEVC video, so they do not need re-encoding at all: swapping the container to MP4 is enough, and that swap is lossless and near-instant.
Why iPhones record MOV in the first place
MOV is Apple's QuickTime container, the native format of the iPhone camera and many Mac apps. Inside, the actual video is usually standard H.264 or HEVC — the same codecs MP4 uses. The incompatibility is purely the wrapper: many Windows apps, Android phones, TVs and web platforms simply expect the MP4 box around those streams.
Convert step by step
- Open the MOV to MP4 converter in your browser.
- Drop the .mov file in. The tool tries a lossless stream copy first.
- Watch the badge: 'lossless remux' means your pixels were untouched — the conversion took seconds.
- If the source codec cannot live in MP4 (ProRes, some PCM audio), the tool automatically re-encodes to H.264/AAC instead and the badge says so.
- Download out.mp4 — it now plays on Windows, Android, TVs and everywhere else.
HEVC footage: one nuance worth knowing
Newer iPhones default to 'High Efficiency' (HEVC/H.265). HEVC travels inside MP4 legally, so those files remux losslessly too — but a few older players cannot decode HEVC no matter the container. If your recipient still cannot play the file, re-encode to H.264 via the compress tool, or switch the iPhone camera to 'Most Compatible' in Settings > Camera > Formats for future recordings.
Batch reality check
Converting a camera roll's worth of clips? Because the lossless path finishes in seconds per file, doing them one by one in the browser is perfectly practical for a dozen files — and each one stays on your machine the whole time.
Our own numbers
On 22 July 2026 we remuxed an H.264+AAC MOV in the browser: the 85,361-byte source became an 85,290-byte MP4 in 14 seconds including engine download — byte-for-byte identical streams, container-only change. A PCM-audio MOV correctly fell back to a one-second H.264/AAC re-encode with the badge reporting it.

Frequently asked questions
Does converting MOV to MP4 lose quality?
Usually no. Most MOVs carry MP4-compatible codecs, so the streams are copied bit-for-bit. Only incompatible codecs trigger a re-encode, and the tool tells you when that happens.
Why is the converted file almost the same size?
That is the proof of losslessness: a remux changes only the container, a few kilobytes of metadata — the media itself is byte-identical.
