About M4V to MP4 conversion

M4V is Apple's variant of MP4, used by iTunes, some Apple exports and apps such as HandBrake. Inside, it is usually the same video an MP4 holds, but some players, editors and upload forms only recognise the .mp4 extension. Converting M4V to MP4 here repackages the video into a standard MP4 without re-encoding it, so it is quick and the quality does not change.

How to convert M4V to MP4

Drag your M4V file onto the page, or click to browse. It stays on your device.
Click Convert to MP4. The first run downloads FFmpeg (about 25 MB); after that it is fast.
Most files are repackaged without re-encoding. If one cannot be, it is re-encoded to H.264 instead, which takes longer.
Preview the MP4 on the page, then download or share it. No watermark, no sign-up.

What people use it for

Upload forms. Sites and apps that only take .mp4 files.
Windows and Android. Players that do not recognise .m4v.
HandBrake output. Turn .m4v exports into standard .mp4.
Editing apps. Import an MP4 where an M4V is refused.

Good to know: movies and TV shows bought from the iTunes Store are copy-protected and cannot be converted. Your own M4V files convert normally.

Frequently Asked Questions

How do I convert M4V to MP4?▼

Drop your M4V file onto the page and click Convert to MP4. Most files are repackaged without re-encoding, so it takes seconds. Preview the MP4, then download it. Everything runs in your browser, and your video never leaves your device.

Does converting M4V to MP4 lose quality?▼

Usually not at all. The video is copied into the MP4 unchanged. If a file cannot be repackaged, it is re-encoded to H.264 instead, which takes longer and stays close to the original.

Can I convert movies I bought on iTunes?▼

No. iTunes Store purchases are copy-protected (DRM), and this converter cannot read protected video. Your own M4V files, such as exports and HandBrake output, convert normally.

Is my video uploaded to a server?▼

No. The conversion runs on your own device using FFmpeg compiled to WebAssembly, so your video never leaves your device.

Is there a file size limit?▼

No fixed cap. The practical limit is your device memory. Repackaging is light, so even long videos usually convert quickly.
