Turn your M4V file into an MP4 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.
MP4 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 MP4, or keep editing the file in REQO.
M4V is Apple’s flavour of MP4. Technically it is nearly the same file, but the extension trips up upload forms and players, and iTunes-purchased M4Vs may carry DRM.
The practical problem: Upload forms and players reject the .m4v extension even though the contents are MP4-compatible. Some M4V files from the iTunes Store are DRM-protected and will not convert.
MP4 solves that. Plays natively on every phone, browser, TV and editing app with no extra codecs. Every upload form accepts it, from YouTube and LinkedIn to Slack and email. H.264 keeps files small enough to send while still looking sharp at 1080p.
M4V is nearly MP4 already, but the extension is enough to make upload forms and players refuse it. One pass through the converter gives you a plain MP4. DRM-protected M4V files bought from the iTunes Store cannot be converted by any tool.

| Typical codecs | H.264, AAC | H.264 video, AAC audio |
| Best for | Video bought or exported from Apple apps | Sharing anywhere, uploads, web embeds |
| Plays on | Apple devices; often fine elsewhere after a rename | Every phone, browser, TV and editor |
| File size | Same as MP4 | Small for the quality |
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 MP4 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 M4V 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.
