MOV to MP4 Converter

Turn MOV files into MP4 in a couple of clicks. MOV is Apple's QuickTime container, common from iPhones and cameras; MP4 is the default video container of the internet. Some detail is discarded to fit the target format; how much depends on the format and your settings.

How to use it

  1. 1

    Add your MOV files

    Drag them onto the drop area, choose them from your device, or paste them from your clipboard. You can queue several at once. Nothing is sent anywhere — the file stays on this device.

  2. 2

    Adjust the settings if you want to

    The defaults suit most people. Open Advanced to control codec, resolution and bitrate and the audio track.

  3. 3

    Convert and download

    Press Convert. Everything happens on your own device — nothing is uploaded. Download files one by one, or grab them all as a ZIP.

Privacy, in plain words

Is it safe? Your MOV file is not uploaded anywhere

What “uploaded” normally means. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website. That copy is what the word “upload” means, and it is the part nobody explains.

What happens instead. This site does not do it. There is no server here that receives files, so your MOV file is read, converted and handed back by the browser you are using right now. It never travels — so there is no copy to store, read, leak or hand over.

Check it yourself in ten seconds

Turn off your Wi-Fi after this page has loaded, then convert a file anyway. It still works, because everything needed is already on your device.

The longer explanation of how this works, and the full detail of what is and is not stored on the privacy page.

Why this matters more than it sounds

Video is the format where the thing being converted is usually a recording of people, and often of people who did not expect a third party to have a copy. It matters more than it sounds, because of what video files usually are:

Family videos

children, addresses, the inside of your house

Medical or therapy consultations

clinical recordings under strict handling rules

Unreleased footage

material under embargo or still being edited

Recorded meetings and calls

everything said, by everyone in the room

A file that is never sent cannot be kept, leaked, subpoenaed or used to train anything. That is a property of how this works, not a promise about how carefully it is run.

MOV and MP4 explained

MOV is Apple's QuickTime container. Structurally it is very close to MP4 — the two share an ancestor — but MOV files often use codecs like ProRes that general-purpose players cannot decode.

MP4 is a container, not a codec. It usually holds H.264 video and AAC audio, and that specific combination is the closest thing the internet has to a universal video format.

Where MOV files come from
iPhone and Mac screen recordings, and professional video editing.
Where MP4 is used
Phone cameras, screen recorders, and every video streaming platform.

MOV vs MP4

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

Why convert MOV to MP4?

People make this switch when they run into the limits of MOV: sharing with anyone outside the Apple ecosystem, or uploading to the web. MP4 is the better fit when you want the video to simply play, anywhere, for anyone.

MOV limitations that prompt the switch
Windows and Android support is inconsistent. Browsers generally will not play it. ProRes files are enormous.
What you give up
H.264 carries patent licensing obligations for commercial distribution at scale. Less flexible than MKV for multiple audio tracks and subtitles.

Does converting MOV to MP4 reduce quality?

MP4 compresses without discarding data, but it cannot represent everything an MOV file holds. What does not fit is discarded permanently, so converting the result back will not restore it. Keep the MOV original if it is the only copy.

“MP4” tells you nothing about quality. An MP4 can hold anything from a pristine 4K master to a heavily compressed clip.

Measured, not estimated

What converting MOV to MP4 actually costs

It depends entirely on the content: across the samples the MP4 ranged from about the same size to 11% larger, with a middle case 6% larger.

Each row is one sample chosen to isolate a property these formats treat differently.

Produced by this site's own converter. The same code that runs in your browser, at the same default settings, so these are the bytes you would download.

Samples are generated from a fixed seed rather than taken from real photographs or documents, so the corpus is reproducible and carries no licensing question — and so the numbers predict the shape of your result rather than its exact size.

MOV to MP4 Converter — questions

How do I convert MOV to MP4?

Drop your MOV file onto the area above, then press Convert. The MP4 file saves straight to your device. You do not need an account, and there is no watermark.

Is it safe to convert MOV files here — are they uploaded to a server?

No, nothing is uploaded. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website; it is converted there and sent back. That copy is what "upload" means, and it is the part that puts your file out of your control. This site does not do it. Your MOV file is read and converted by the browser you are using right now and never leaves this device, so there is no copy for anyone to store, read or hand over. You can prove it: turn off your Wi-Fi after this page loads and the conversion still works.

Can I convert confidential MOV files, like bank statements or contracts?

Yes, and that is the case this site was built for. Because the file never leaves your device, a confidential document is no more exposed than it is sitting in your own folder — there is no transfer, no copy on someone else's hardware, no retention period to read about and no staff with access. Nothing is logged about the file either: not its name, not its size, not its contents. The one thing worth saying plainly is that this protects the file in transit and at rest on our side, not from anything already on your own computer.

Does converting to MP4 reduce quality?

Yes, though not through compression — MP4 stores what it holds without discarding data, but it cannot hold everything a MOV file does. What does not fit is dropped permanently, and converting the result back will not bring it back.

How large a file can I convert?

Up to 512 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.
