The format
What is an MP4 file?
MPEG-4 Part 14
MP4 is the most widely supported video format. It usually holds H.264 video with AAC audio, a combination that plays on practically every phone, computer, TV, and website. It balances quality and file size well, which is why most cameras, phones, and editors export to it.
What opens MP4 files
Everything: Windows Media Player and Films & TV, QuickTime and Photos on Mac, iPhone, Android, smart TVs, VLC, and every major website and video editor.
FAQ
Questions, answered
Is the MP4 converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. Everything runs inside your browser with Mediabunny and your browser's WebCodecs video encoders, so your files never leave your device. Once the page has loaded, it even works offline.
Does it work on iPhone, Android, Mac, and Windows?
Yes. It works in current versions of Chrome, Edge, Safari, and Firefox. Phones handle short clips well, and long or 4K videos convert best on a computer.
What can I convert MP4 to?
MOV, WebM, MKV, MP3, WAV, M4A, OGG, FLAC, AAC, GIF, AVI, WMV, and MPEG. Pick the format after adding your file.
