How to convert MOV to MP4
The converter re-encodes the video into a standard MP4 file. You do not need to choose a codec, quality or resolution.
Step-by-step
- Choose a MOV file or drag it onto the upload area. On an iPhone, you can pick a video straight from Photos.
- Wait for the upload to finish, then click Convert to MP4.
- Wait while the video is converted. Long or 4K videos take longer.
- Download the MP4 and play it on the device or website where the MOV did not work.
What you get
The result is built for compatibility rather than for the smallest possible size:
- H.264 video with 8-bit 4:2:0 color, which practically every phone, computer, TV and browser can play.
- AAC audio, the standard audio format for MP4.
- HDR video from an iPhone converted to standard dynamic range, so colors do not look washed out on regular screens.
- The original resolution and frame rate. An odd width or height is rounded down by one pixel, because H.264 needs even dimensions.
- Fast start for the web: the MP4 can start playing in a browser before it has fully downloaded.
Why an iPhone MOV may not play on Windows or Android
On supported iPhones, the default High Efficiency setting records HEVC (H.265), and iPhone 12 and newer often record in HDR. The MOV file itself is fine: Windows, older Android phones and TVs often fail on the codec inside, and HDR looks gray on screens without HDR support. The converter re-encodes HEVC to H.264 and maps HDR to standard range. If the file is already MP4, check the video codec: MP4 can contain HEVC too. For HEVC video that your device cannot decode, use HEVC to MP4 Converter.
If you only need to play the file on your own PC or phone, see this guide: How to Play MOV Files on Windows and Android.
MOV and MP4: what is the difference?
MOV is Apple's QuickTime container, and MP4 is a standard container based on it. Both can hold the same video and audio codecs, which is why renaming a .mov file to .mp4 sometimes seems to work. It fails when the MOV contains something MP4 players do not expect, such as HEVC with HDR, ProRes from a camera or uncompressed PCM audio.
Converting rewrites the video and audio into codecs every MP4 player understands, so the result does not depend on what the original contained.
When to convert MOV to MP4
Convert when the MOV has to work somewhere outside the Apple ecosystem:
- Playing on Windows, Android or a smart TV that shows a black screen, plays only the sound or refuses the file.
- Uploading to a website, LMS, CMS or online form that accepts only MP4.
- Editing in software that does not import HEVC or HDR footage.
- Sending a video to someone who does not use a Mac or an iPhone.
Converting MOV to MP4 on a Mac
QuickTime Player can only export MOV files, so it does not help here. iMovie can save MP4 (File > Share > File), but it means importing the clip into a project first.
This converter works in any browser, including Safari, with no software to install. Upload the MOV, convert it and download the MP4.
Quality, file size and limits
The MP4 can be larger or smaller than the MOV: HEVC files from an iPhone are very efficient, so the H.264 version is often bigger. If the result is too large to share, run it through the video compressor.
Files can be up to 200 MB. Transparency (an alpha channel, for example in ProRes 4444) is not kept, because MP4 with H.264 does not support it. If the MOV has several audio tracks, the MP4 gets the default one, usually the first. For longer videos, use the full Deus Video online editor: it accepts files up to 1 GB, with no size limit on the Maxi plan, and exports MP4.

Frequently Asked Questions
Common questions about converting MOV files to MP4.
Is the MOV to MP4 converter free?
Yes. It is free, you do not need an account, and the MP4 has no watermark.
Will converting MOV to MP4 reduce quality?
The video is re-encoded, so it is not lossless, but the settings keep the original resolution and frame rate and aim to keep the difference hard to see. HDR video is converted to standard dynamic range so it looks right on ordinary screens.
Why does my iPhone video play only sound on Windows?
The video track is most likely HEVC (H.265), which Windows often cannot decode without an extra extension. Converting to MP4 with H.264 makes the video play without installing anything.
Can I convert MOV to MP4 on an iPhone?
Yes. Open this page in Safari, choose a video from Photos or Files, convert it and download the MP4 to your iPhone.
Is there a file size limit?
Yes, files can be up to 200 MB. If a recording is larger, trim it first, for example in the Photos app on the iPhone, and convert only the part you need.
Can I convert MP4 back to MOV or to another format?
Yes. For MP4 to MOV there is a separate page: MP4 to MOV Converter. For WebM, MKV, AVI or another format, use the video converter.
