About MOV to MP4

MOV is a video container format developed by Apple. While it is high-quality, it can often be difficult to play on non-Apple devices or legacy Windows software. MP4 is the most widely supported video format in the world today.

Our tool uses Client-Side Rendering (CSR). Instead of uploading your large video files to a server, we run the conversion engine directly in your web browser. This means your private videos never leave your device.

How to Convert MOV to MP4

  1. Select Video: Drag and drop your .mov files or click the box to browse your storage.
  2. Engine Setup: If this is your first visit, the browser will download the FFmpeg engine (approx. 25MB).
  3. Convert: Click the "CONVERT TO MP4" button to begin transcoding.
  4. Save: Once the status shows complete, the MP4 file will download automatically.

Frequently Asked Questions

Is there a file size limit?

We don't set a limit, but your browser's memory does. Large 4K videos may require a computer with significant RAM to process smoothly.

Will I lose video quality?

We use high-quality encoding settings (CRF 22) to ensure that the MP4 output looks almost identical to your original MOV file.

Does this work on iPhone?

Yes! You can convert MOV files from your camera roll directly into MP4 using Safari or Chrome on your iPhone.

Why does it say "Loading core engine"?

The tool uses a powerful library called FFmpeg.wasm. It needs to load this engine into your browser's memory before it can start converting videos.
