About the M4V to MP4 Converter
Need to turn a M4V file into MP4? This free converter changes M4V videos into MP4 in a few seconds, right in your browser. People usually convert because M4V is Apple-centric and some players and portals do not recognise it, while MP4 gives you an MP4 that plays on every device. MP4 files open in every phone, smart TV, browser, VLC, Windows and macOS.
Audio and video are processed by FFmpeg compiled to WebAssembly, the same open-source engine behind VLC and HandBrake, running inside your browser tab. Because everything happens on your own device, your videos are never uploaded, stored or seen by anyone else, which makes it safe for family videos, client footage and private recordings.
What to expect: the resolution is kept unless you choose a smaller size, and the audio track is converted too; the processing engine (about 30 MB) is downloaded once and then cached by your browser.
How to use the M4V to MP4 Converter
- Click "Choose files" or drag your M4V videos onto the box. You can add several at once.
- Choose the output resolution and quality preset.
- Press "Convert to MP4". The conversion runs on your device and shows its progress.
- Download each MP4 file, or use "Download all (ZIP)" when you converted several.
- Open the result in every phone or smart TV to check it; your original M4V is never changed.
Tips & benchmarks
- The MP4 uses H.264 video and AAC audio, the combination every phone, TV and social network accepts.
- Very large videos (over about 1 GB) may exceed the memory of a phone browser; trim them first with our Trim Video tool.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the MP4 to a website or government portal.
