What is an AAC file?
Advanced Audio Coding
AAC is the lossy audio codec used by Apple Music, YouTube, and most streaming services. A .aac file is raw AAC audio without the MP4 container that M4A files have, so some players can't show its length or cover art.
What opens AAC files
Most phones and computers, VLC, browsers, and car stereos that support AAC. For Apple apps and editors, M4A is often the safer choice.
FAQ
Questions, answered
Is the AAC 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.
