How to convert MP4 to MOV

  1. 1

    Drop the MP4

    Or any MOV, MKV or WebM. The file is read on your computer, so a big one is fine.

  2. 2

    Pick MOV

    Or MKV, or WebM. Under the buttons you'll see whether it's a quick copy or a full re-encode.

  3. 3

    Get the file

    It lands in your Downloads. Files over 150 MB are written straight to a folder you choose.

Which format to pick

For a phone or camera MP4 (H.264 or HEVC video, AAC sound).

MOV

Copied in seconds

For QuickTime and Apple editing apps, or a form that only takes .mov. The video and sound inside don't change.

MKV

Copied in seconds

Takes any video and sound as they are. Good for VLC, Plex and media players on a TV.

WebM

Re-encoded

For a video on a web page. A 20-second 1080p clip took 34 seconds on a 2-core machine.

AVI · WMV

Browsers can't write these formats, so this page doesn't offer them.

Questions

Is my video uploaded anywhere?

No. The conversion runs in your browser on your computer. The video never reaches our server, and we don't see its name.

Will the MOV look worse than the MP4?

No. MP4 and MOV are two kinds of wrapper for the same H.264 or HEVC video, so the page copies the video and sound into the new wrapper without touching them. The file size stays about the same.

Why did my MOV come out the same size?

Because nothing was compressed. If you need a smaller file, use the MOV compressor.

My MP4 has VP9 or AV1 video. What happens?

Apple apps often can't open those inside a MOV, so for MOV the video is re-encoded to H.264. That takes longer. MKV keeps any video as it is.

Can I convert several files at once?

Not on this page, it takes one file at a time.
