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 already asked for: the AI assistant's request says MP4, so one drop does it. Want a particular resolution, frame rate or bitrate? Just say so.
Batch friendly: the classic converter on this page takes several MOV files in one go and downloads them as a ZIP.
Free, no watermark: no sign-up, and 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 up to the roughly 2 GB per-file ceiling; they simply take longer than 1080p.

Is this MOV to MP4 converter free?

Yes. Converting MOV to MP4 on MediaConverter.io is free, with no watermark and no sign-up. The AI assistant runs on a free daily allowance of assistant credits; the classic converter on this page has no daily limit at all.

Are my MOV files uploaded to a server?

No. The conversion runs inside your browser using WebCodecs and FFmpeg compiled to WebAssembly, so your .mov file is read and converted on your own device and never uploaded, which keeps private recordings private and means there is no waiting in an upload queue. The AI assistant only sees what you type and basic facts about the file: its name, format, duration and size.

Is there a file size limit for MOV to MP4?

There is no plan or account limit, but the converter loads the whole MOV file into your browser's memory, so about 2 GB per file is the practical ceiling; larger files may fail to open. Long or high-resolution files also take longer, especially on phones.

Can I choose the MP4 settings myself?

Yes. Ask the AI assistant for a resolution, frame rate or bitrate in your request. Audio and subtitle track selection, the codec list and every other setting are in the classic converter, one click away on this page.

Which browsers support the MOV to MP4 converter?

It is built and tested on current desktop Chrome and Edge, which are also fastest because they expose hardware-accelerated WebCodecs video decoders. Recent Firefox and Safari releases support the same web APIs; if a file fails there, try Chrome or Edge.
