MOV to MP4 converter

To convert MOV to MP4, drop the files here and press Convert to MP4. A MOV from an iPhone or a Mac holds H.264 or HEVC video and AAC sound, which MP4 holds too, so they're copied across as they are: no quality lost, done in seconds. Free, and nothing is uploaded.

A free tool from Clyper, the AI clipping tool that turns long videos into captioned vertical clips.

Get started

Converted on your device: nothing is uploaded.

Make HEVC (H.265) videos H.264iPhones record HEVC. Copied into MP4 it plays on phones, Macs and most browsers, but some Windows PCs and editors can't open it. H.264 plays everywhere; it's re-encoded, so it takes about as long as the video plays.

Free, no watermark, nothing to sign up for. Copying has no length limit; up to 60 minutes of a video can be re-encoded at a time.

How to convert MOV to MP4

Drop your MOV files in, or choose them: up to 20 at once. Each one shows what it holds and whether it'll be copied or re-encoded.
Tick Make HEVC videos H.264 if the MP4 has to play on any Windows PC or open in an older editor. Leave it off to keep it quick and lossless.
Press Convert to MP4. A copy takes seconds, even for a long video. Anything re-encoded takes about as long as it plays.
Download each MP4, or all of them at once.

MOV and MP4 side by side

MP4 was built on Apple's QuickTime format, so a MOV and an MP4 are close relatives: the same kinds of picture and sound fit in both. The difference is where they open.

Where MOV files come from

iPhones. A video copied off an iPhone as the original is a MOV. With the camera set to High Efficiency (the setting Apple offers on every iPhone since the iPhone 7), the picture is HEVC; set to Most Compatible, it's H.264. Sent by AirDrop, Messages or email, Apple may convert it to H.264 for a device that can't play HEVC; through iCloud Photos it stays as it was shot.

Mac screen recordings. A Mac saves them as MOV files named “Screen Recording [date] at [time].mov”. Converted here, a recording keeps every pixel, which matters for text on screen.

OBS on a Mac. New OBS profiles record Hybrid MOV on macOS (Hybrid MP4 on Windows and Linux), so a stream or a call recorded on a Mac is often a MOV too.

The one reason to re-encode: HEVC

HEVC keeps the same quality in less space, so an iPhone's MOV copied into an MP4 is small and sharp, and plays on phones, Macs and most browsers. But some Windows PCs need Microsoft's HEVC Video Extensions to play it, and some editors won't open it. If the MP4 is for someone else's PC, tick Make HEVC videos H.264: it takes about as long as the video plays and makes a bigger file that plays everywhere.

ProRes MOVs from cameras and editors can't be converted in a browser. To make a big MP4 smaller afterwards, use the video compressor, and for the long version of all this, read how to convert MOV to MP4.

Filmed something long on your iPhone?

A talk, an interview or a podcast filmed on a phone doesn't need converting before it goes to Clyper: upload the MOV as it is. Clyper finds the moments worth posting, cuts each on whole sentences, frames it 9:16 on whoever is talking and captions every word.

Questions

Does converting MOV to MP4 lose quality?

Not here, for almost every MOV. iPhone and Mac videos hold H.264 or HEVC video and AAC sound, which an MP4 holds too, so they're copied across untouched. Only PCM sound (from some cameras) is re-encoded, to AAC, and only HEVC is re-encoded if you ask for H.264.

Can I just rename a .mov file to .mp4?

Sometimes it plays, because the two formats are close relatives, but it's still a MOV inside and some apps and upload forms reject it. Converting rewrites it as a real MP4, and when the picture and sound are copied it takes about as long as renaming feels like it should.

Why won't my iPhone video play on Windows?

iPhones record HEVC (H.265) when the camera is set to High Efficiency, and some Windows PCs can't play HEVC without Microsoft's HEVC Video Extensions. Tick Make HEVC videos H.264 before converting and the MP4 plays on any PC.

How do I make my iPhone record H.264 instead?

Open Settings, then Camera, then Formats, and choose Most Compatible. New videos are then H.264, and copy into an MP4 that plays everywhere.

Can I convert a Mac screen recording to MP4?

Yes. A Mac saves screen recordings as MOV files named Screen Recording followed by the date and time. Drop one or several here and they come out as MP4s with the same picture.

Is there a limit?

Up to 20 MOV files at once, of any length. Files over 1 GB are written straight to your disk, which needs Chrome or Edge on a computer. Nothing is uploaded, and there's no watermark.
