Turn your MP4 file into a MOV that plays where you need it, right in your browser.
Drag and drop the file, or click to browse. Files up to 500 MB are supported, and nothing is installed.
MOV is already selected, so there is nothing to configure. You can switch formats in the panel if you need to.
We convert on our servers, usually in under a minute. Create a free account to download the MOV, or keep editing the file in REQO.
MP4 is the closest thing video has to a universal format: an MPEG-4 container that almost always holds H.264 video and AAC audio, which every browser, phone, TV and social platform can play without a plugin.
The practical problem: MP4 is already the safest format, so the usual reason to convert away from it is a specific destination that wants something else.
MOV solves that. Keeps the file native to macOS, iOS and Final Cut Pro. Preferred by some Apple-first editing and motion tools.
Usually done to keep an Apple-first editing workflow happy: Final Cut, iMovie and some motion tools prefer a MOV container. The video stream is re-encoded but the picture and audio survive intact.
| MP4 | MOV | |
|---|---|---|
| Container | MPEG-4 Part 14 | Apple QuickTime |
| Typical codecs | H.264 video, AAC audio | H.264, HEVC or ProRes |
| Best for | Sharing anywhere, uploads, web embeds | Editing on a Mac, footage straight off an iPhone |
| Plays on | Every phone, browser, TV and editor | macOS and iOS natively, patchy elsewhere |
| File size | Small for the quality | Large, especially ProRes |
Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the MOV itself beyond the free-plan badge.
No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android.
Converting re-encodes the video, so it is not bit-for-bit identical. We encode at a high quality target, which keeps the result visually indistinguishable from the MP4 on normal viewing. Converting the same file back and forth repeatedly will eventually show, so keep your original.
Up to 500 MB per file. For anything bigger, trim or compress it first, both are free tools here.
Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
