Lossless

H.264 .mov files are copied to MP4, no re-encode

Free

No account, no size-limit tricks, no watermark

Three steps

How it works

  1. Upload your MOV

    Drag in or choose a .mov file (or any video). It stays on your computer, and nothing is sent anywhere.

  2. We convert it to MP4

    If the video is already H.264/AAC (most iPhone and QuickTime recordings), it is copied straight into an MP4 container, instant and lossless. Other codecs are transcoded in your browser.

  3. Play & download the MP4

    Preview the result, then download the .mp4, ready to play anywhere, upload, or drop into any editor.

Why people choose it

Lossless when it can be

Most .mov files from iPhones and QuickTime are already H.264/AAC, exactly what MP4 uses. This tool copies the video and audio straight across without re-encoding, so there is zero quality loss and it finishes almost instantly.

Transcodes when it must

If your MOV uses a codec MP4 does not support, it is transcoded in your browser with WebCodecs, the same hardware-accelerated pipeline pro web video tools use. You still get a clean, playable MP4.

100% private

The whole conversion runs on your own device. Nothing is uploaded and no account is needed. Safe for personal recordings, unreleased footage and client work.

No size paywall or watermark

Because it runs on your machine there is no per-file charge and no branding stamped on your video. Bigger files simply take a little longer.

Plays everywhere

MP4 (H.264) is the most compatible video format there is: Windows, Android, every social platform and editor accepts it, where a .mov sometimes will not.

Nothing to install

It is a web page, not an app. Open it, drop a MOV in, and get an MP4, and it works in Chrome, Edge and other modern desktop browsers.

How to convert MOV to MP4 for free

A .mov is Apple’s QuickTime container, great on a Mac or iPhone, but awkward on Windows, Android and some editors and upload forms. Converting MOV to MP4 fixes that: MP4 is the most widely-supported video format, so the file just plays. Drop your MOV onto this tool and it hands you an MP4, right in the browser.

The clever part is that most MOV files, especially iPhone recordings and QuickTime exports, already use the H.264 video and AAC audio codecs that MP4 uses. When that is the case the tool simply rewraps the same streams into an MP4 container instead of re-encoding them. That means the conversion is near-instant and completely lossless: the picture is byte-for-byte identical, just in a file that plays everywhere.

Convert MOV to MP4 without uploading anything

Typical online converters make you upload your video to their servers, wait in a queue, then download the result, which is slow, and a privacy problem for personal or confidential footage. This MOV to MP4 converter is different: the whole thing runs on your own device. Nothing is uploaded, there is no account, and there is no watermark on the finished MP4.

It works for the whole family of QuickTime files: an iPhone MOV to MP4, a screen recording, or a QuickTime export to MP4, and it also accepts MP4, WebM and MKV if you need to normalise those to a standard MP4.

When the file has to be transcoded

Occasionally a .mov holds a codec MP4 cannot carry (for example ProRes from a pro camera). In that case the tool transcodes the video to H.264 using the browser’s built-in, hardware-accelerated WebCodecs, which takes longer than a straight copy but still runs locally and still gives you a clean, playable MP4. We keep it honest: if a file genuinely cannot be converted in the browser, the tool tells you rather than producing a broken result.

Questions

Frequently asked questions

How do I convert a MOV to MP4 for free?

Drop your .mov file onto the tool and click Convert to MP4. It converts the video in your browser and lets you download the .mp4, free, with no sign-up and nothing uploaded.

Does converting MOV to MP4 lose quality?

Usually not at all. Most MOV files (including iPhone and QuickTime recordings) are already H.264/AAC, so the tool copies the exact video and audio into an MP4 container without re-encoding, a lossless conversion. Only files with an incompatible codec are transcoded.

Can I convert an iPhone MOV to MP4?

Yes. iPhone videos are H.264 (or HEVC) in a .mov container. H.264 recordings are rewrapped to MP4 losslessly; other codecs are transcoded. Either way you get a standard MP4 that plays on Windows, Android and social platforms.

Is my video uploaded to a server?

No. The conversion runs entirely on your own device and the MP4 is built in your browser. Nothing is uploaded and no account is needed, so it is safe for private footage.

Is there a file-size limit?

There is no artificial cap. Because conversion happens in memory on your machine, extremely large files are bounded by your device’s available memory. Lossless copies (H.264 MOV) handle big files easily; transcodes take longer.

Why won’t my MOV play on Windows or when I upload it?

MOV is Apple’s QuickTime format, and some Windows players and upload forms don’t accept it. Converting it to MP4 (H.264), the universal video format, makes it play and upload everywhere.

Does the MP4 have a watermark?

No. There is no watermark and no branding added to your video. The output is a clean MP4.

Which browsers does it work in?

It works in modern desktop browsers with WebCodecs support. Chrome and Edge are the most reliable. The whole conversion is client-side, so no install is needed.
