How to Convert MOV to MP4 on Windows

iPhone videos, GoPro footage, and Mac screen recordings all come as MOV files. Windows can't open MOV natively — Windows Media Player shows an error, and File Explorer can't even generate thumbnails. Converting to MP4 fixes this instantly and gives you a file that plays in every Windows application without any codec installation. Here's how to do it free in your browser.

Open MOV to MP4 Converter

Step-by-step instructions

  1. 1

    Open the FormatDrop MOV to MP4 converter in Chrome, Firefox, or Edge

    Navigate to formatdrop.com/mov-to-mp4 in your Windows browser. The converter loads ffmpeg (the professional-grade video processing library) directly into your browser tab using WebAssembly. No software installation required — no ffmpeg download, no VLC, nothing.

    Go to converter
  2. 2

    Select your MOV file from Windows

    Click the drop zone to open the Windows file picker, or drag your MOV file directly from File Explorer. MOV files from iPhone are typically in your Downloads folder (from iCloud), in the Pictures folder (from Windows Photos sync), or on a connected iPhone accessible through This PC. GoPro MOV files are usually on the SD card.

  3. 3

    Convert MOV to MP4

    The converter checks whether the MOV file's video codec (H.264 or H.265) is compatible with MP4. In most cases it is, and the conversion is a fast lossless remux — the file is repackaged in seconds without any quality loss. If the MOV uses ProRes or another Apple codec, ffmpeg transcodes to H.264, which takes longer but is still free.

  4. 4

    Download and play your MP4 on Windows

    Click Download to save the MP4. The file now plays in Windows Media Player, Windows Photos app, Microsoft Movies & TV, VLC, Chrome browser, and every other Windows application. You can also upload it to YouTube, Instagram, TikTok, or any video platform.

Why convert MOV to MP4?

Windows and MOV have a long-standing incompatibility. Apple's QuickTime Player for Windows was discontinued in 2016 with a security advisory to uninstall it — Apple no longer maintains a Windows QuickTime. Without QuickTime, Windows has no built-in MOV codec. Windows Media Player shows a codec error. Even Windows 10 and 11's native media player can't open most MOV files without additional codecs. The practical workaround for years was to install VLC, which includes its own codec library. But the simpler, faster fix for occasional MOV files is to convert to MP4 in a browser. The resulting MP4 plays natively in every Windows application without any codec installation — and since most iPhone MOV files already use H.264 or H.265 video, the conversion is usually a lossless remux that completes in seconds.

Your files never leave your device

FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.

Frequently asked questions

Can Windows 10 or 11 open MOV files natively?
Not reliably. Windows 10/11 can play some MOV files through the Windows Media Player or Movies & TV app, but support is inconsistent depending on the video codec inside the MOV. MOV files with H.264 sometimes work; MOV files with ProRes, ProRes RAW, or older QuickTime codecs do not. Convert to MP4 for guaranteed playback on any Windows version.
Is there a free way to convert MOV to MP4 on Windows without software?
Yes — FormatDrop in Chrome, Firefox, or Edge converts MOV to MP4 without any software installation. The conversion runs in your browser using WebAssembly. For repeated conversions or large batches, downloading HandBrake (free, open-source) is a good alternative that handles any video format.
Can I open MOV files on Windows without converting?
Yes — install VLC media player (free, open-source). VLC includes its own codec library and plays virtually every video format including MOV, MKV, AVI, and others without any additional codec installation. If you need to play MOV files regularly but not convert them, VLC is the easiest solution. If you need to share, upload, or use the video in editing software, convert to MP4.
How do I transfer MOV files from iPhone to Windows?
Main methods: (1) USB cable — connect iPhone, trust the PC, open File Explorer, navigate to This PC → [iPhone] → Internal Storage → DCIM. Copy MOV files from there. (2) iCloud for Windows — install the iCloud app from Microsoft Store; iPhone videos sync to your Pictures folder. (3) AirDrop to Mac then transfer to Windows PC. (4) Upload to Google Drive or Dropbox from iPhone, download on Windows.
