How to Convert MOV to MP4 (iPhone Videos on Windows)

You filmed something on your iPhone, copied it to your Windows PC, and now the file won't play — or a website refuses to accept it for upload. The file is a .mov, the format iPhones use for video, and Windows doesn't always get along with it.

The reliable fix is to convert it to MP4, the format that plays everywhere. Here's how, free and in your browser.

How to convert MOV to MP4 for Windows

QuickWand's free video converter runs entirely in your browser, so your video never leaves your computer.

  1. Open the video converter.
  2. Drag your .movfile into the drop zone, or click to browse. The first time you do this the tool loads a small video engine (about 25 MB) — give it a few seconds.
  3. Choose MP4 as the output format.
  4. Click Convertand download the MP4. It'll play in Windows Media Player, the Photos app, and any browser, and it uploads to sites that rejected the .mov.

Why iPhone .mov files trip up Windows

There are really two things going on. First, the container: iPhones wrap video in the .mov (QuickTime) container, while the Windows world standardized on .mp4. Second, the codec: modern iPhones encode with HEVC (also called H.265) to save space. Plenty of Windows apps and upload forms can't decode HEVC, so even when a player opens the file you may get sound but no picture — or nothing at all.

Converting to MP4 with the widely supported H.264 codec clears both hurdles at once. MP4/H.264 is the closest thing video has to a universal format: phones, PCs, browsers, editors, and upload forms all accept it.

Stop the problem at the source (optional)

If you send iPhone videos to a PC often, you can make your iPhone record in the more compatible format: open Settings → Camera → Formats and choose Most Compatible. New recordings use H.264, though they're still .movfiles — so for guaranteed playback on Windows, converting to MP4 is still the safest move.

After converting: trim or shrink if needed

Once it's an MP4, the rest is easy. If the clip is longer than you need, cut it with the video trimmer. If the file is too large to email or upload, run it through the video compressor. And if you only need the audio — a voice memo or a recorded talk — pull it out with MP4 to MP3.

Convert MOV to MP4 once and your iPhone videos will play, upload, and share on Windows without a fight.

Frequently asked questions

Why won't my iPhone .mov video play or upload on Windows?
iPhones record video as .mov files, often using the HEVC (H.265) codec. Windows Media Player and many upload forms either can't play that codec or don't accept the .mov container at all, so the video fails. Converting it to MP4 (H.264) makes it play and upload everywhere.
Is converting MOV to MP4 free, and is it private?
Yes. QuickWand's video converter is free with no sign-up or watermark, and the conversion runs in your browser, so your video is never uploaded to a server.
Will converting MOV to MP4 reduce the video quality?
Any re-encode involves some compression, but at sensible settings the difference is not noticeable. MP4 with the H.264 codec is the most widely compatible choice, so it's worth it for video that needs to play or upload anywhere.
Why does the converter take a moment on the first video?
On its first use the tool loads a small video engine (about 25 MB) into your browser so it can convert files locally. That happens once and takes a few seconds; conversions after that start right away.
