How to convert MP4 to MOV

Choose an MP4, select automatic conversion or H.264 and AAC compatibility, and download a MOV. The converter runs locally in your browser, remuxes compatible tracks without changing their quality, and transcodes only when the selected option or source codecs require it.

  1. Step 1

    Choose your MP4
    Pick a file or drop it into the converter above.

  2. Step 2

    Choose a conversion
    Use Automatic for speed and original quality, or H.264 + AAC for compatibility.

  3. Step 3

    Download the MOV
    Save the verified MOV when processing finishes.

What to expect

Supported inputs
MP4 video files this browser can read. Other readable video formats may also work, but this page is optimized for MP4 to MOV conversion.
What happens
Automatic conversion copies MOV-compatible tracks for a fast, quality-preserving remux and transcodes incompatible tracks. The compatibility option re-encodes to H.264 video and AAC audio.
Limits
There is no arbitrary upload limit because the file is not uploaded. Large-file capacity and conversion speed depend on your browser, available device memory, processor, and the source codecs.

Your files stay on your device

Your computer does the work, so the file never has to be uploaded, and that’s also why it’s free: there’s no server time for us to pay for. You don’t need an account, and nothing you make gets a watermark.

Questions

Not when the video and audio codecs can be copied into MOV. That fast remux keeps the encoded tracks unchanged. If a codec must be transcoded, or you choose H.264 and AAC compatibility, there can be a small quality change.

There is no arbitrary upload limit because processing stays on your device. Your practical limit depends on the browser, available memory, processor, file duration, resolution, and whether transcoding is needed.

Choose H.264 + AAC compatibility when another editor or device rejects the automatic output. It takes longer and re-encodes the tracks, but those codecs are widely supported in MOV workflows.
