How to Convert MOV to MP4 Online

Upload your MOV file

Drag and drop your .mov file onto the page or click to browse. You can select several MOV files at once to batch-convert them.

MP4 is preselected

The output format is already set to MP4, so you can convert immediately. If you need to, adjust the codec, resolution, frame rate or bitrate in the settings panel first.

Convert and download

Click Convert. The MP4 file is processed on your own device; nothing is uploaded to a server. When it finishes, click Download to save it (or Download all to get a batch as a ZIP).

Why Convert MOV to MP4?

MOV is Apple's format, and while Macs and iPhones play it happily, Windows Media Player, many Android phones, smart TVs and web upload forms expect MP4. Converting MOV to MP4 makes your clip playable and shareable everywhere without changing how it looks.

The converter re-encodes the video with the codec you choose: keep HEVC to match the source, or pick H.264 for maximum compatibility with older devices. Everything runs in your browser, so a 4K iPhone clip never has to be uploaded.

Private by design: your MOV file is converted on your own device and never uploaded.
MP4 preselected: the output format is already chosen, so it is a one-click conversion.
Batch friendly: convert several MOV files in one go and download them as a ZIP.
No limits, no watermark: free for files of any size, with nothing stamped on the output.

MOV vs MP4

MOV (QuickTime File Format): MOV is Apple's QuickTime container. iPhones, iPads and Final Cut Pro record and export MOV natively, and it can hold high-quality H.264, HEVC or ProRes streams. It is best for Apple devices, iMovie and Final Cut Pro workflows.

MP4 (MPEG-4 Part 14): MP4 is the most widely supported video container in the world. It usually carries H.264 or H.265 video with AAC audio, plays on every phone, browser, TV and editing app, and is the safest choice for sharing. It is best for sharing, social media, web playback and mobile devices.

In short: keep MOV when the priority is Apple devices, iMovie and Final Cut Pro workflows, and switch to MP4 when the file is headed for sharing, social media, web playback and mobile devices. Need a different target? The full Video Converter supports every format listed below.

MOV to MP4 FAQ

Will converting MOV to MP4 reduce the quality?

Barely, if you keep the same codec and bitrate: the video is re-encoded at the source's settings, so it looks the same. Choosing H.264 for an HEVC file changes the codec, which older devices need; lowering the bitrate is what visibly reduces quality.

Why won't my MOV play on Windows?

iPhones record HEVC (H.265) by default, which Windows cannot play without a paid extension. Convert MOV to MP4 with the H.264 codec and it will play in any Windows app.

Can I convert 4K MOV files?

Yes. The conversion uses your own computer's hardware, so 4K and 60 fps files are supported; they simply take longer than 1080p.

Is this MOV to MP4 converter free?

Yes. Converting MOV to MP4 on MediaConverter.io is completely free, with no watermark, no sign-up and no daily conversion limit.

Are my MOV files uploaded to a server?

No. The converter runs inside your browser using WebAssembly and WebCodecs, so your .mov file is read and converted on your own device. Nothing is uploaded, which keeps private recordings private and means there is no waiting in an upload queue.

Is there a file size limit for MOV to MP4?

No fixed limit. Because processing happens locally, the practical limit is your computer's memory and patience; multi-gigabyte MOV files convert fine on a desktop browser. Very large files take longer on phones.

Which browsers support the MOV to MP4 converter?

Current versions of Chrome, Edge, Firefox and Safari on desktop all work. Chrome and Edge are fastest because they expose hardware-accelerated WebCodecs decoders.
