Convert MOV to MP4
Make iPhone videos easy to use on Windows, Android and web services. In most cases no re-encoding is needed and it takes seconds.

How to use
- 1
Add videos
Drop MP4, MOV, WebM, MKV and similar files. Several videos can be converted in turn with the same settings.
- 2
Choose the output format
MP4 (H.264), WebM (VP9), MOV or MKV. When the codec already matches, the stream is copied instead of re-encoded, which is very fast.
- 3
Convert and save
Save once the progress bar reaches 100%. Long videos take a while; keep the tab open.
MOV and MP4
MOV is Apple's QuickTime format and MP4 is the standard derived from it. The video codec inside (H.264 or HEVC) is the same, so an H.264 MOV only needs its streams copied into an MP4 container — no quality loss and a few seconds.
MOVs recorded with the iPhone's "High Efficiency" setting use HEVC (H.265), which Windows and others cannot play even inside an MP4, so they are re-encoded to H.264. That takes longer and produces a slightly larger file.
Frequently asked questions
Is quality lost?
Not for H.264 MOVs, which are not re-encoded. HEVC MOVs are re-encoded to H.264 and change slightly according to the Quality setting.
Conversion is slow
Videos recorded in HEVC (High Efficiency) must be re-encoded. On devices with a hardware encoder this takes a fraction of the video's length.
Does it work in the iPhone's browser?
Yes, in iOS Safari 17 or later. Long videos may fail for lack of memory, though, so a desktop is recommended.
Is the audio kept?
Yes. The MOV's AAC audio is copied into the MP4 as-is.
Help us improve the service
If a conversion fails, sending us the circumstances helps us track down the cause. Knowing which devices and formats fail most often, and how long processing takes, lets us revise the supported formats and fix the bugs behind them. If you don't mind, leaving this on is a real help.
What is sent
The tool you used and the settings you chose (output format, quality, etc.), your device specs (GPU, memory, core count), the input format with a rough size, how many files succeeded or failed and how long it took, and the error type and details when something fails.
What is never sent
The files themselves, file names, text, subtitles or prompts you add to a video, and IP addresses. The data goes only to this site's own server, never to a third-party service.
