Convert MOV to MP4 Online - Free, No Upload, No Watermark
An iPhone or Mac video that will not play on Windows, an Android phone or a smart TV is usually a .mov file. Convert it to MP4 (H.264), the most widely supported video format. Your video is processed in your browser, so a private clip is never sent to a server.

- Open the DinoConvert video converter.

- Select MP4 (H.264) as the output format, or WebM (VP9) for the web.
- Press convert and wait: the speed depends on your device.
- Download the MP4 and share it anywhere.
Why do iPhone videos not play on Windows or Android?
iPhones and Macs record in the QuickTime MOV container, often with the HEVC codec. Many Windows PCs, Android phones, TVs and websites do not handle that combination well. MP4 with H.264 is the safe choice that works nearly everywhere.
What to know before converting in the browser
Conversion uses your browser’s built-in WebCodecs technology, which keeps the video on your device. Codec availability depends on your browser and hardware. Chrome and Edge currently offer the broadest support, especially for H.264 encoding.
When to choose WebM instead of MP4
WebM (VP9) is designed for websites and plays natively in modern browsers. Choose MP4 for sharing with people, editing software, social apps and TVs. Choose WebM for embedding on your own site.

| WebM (VP9) | Websites | Modern browsers |
