The format
What is an MP3 file?
MPEG-1 Audio Layer III
MP3 is the most widely supported audio format. Its lossy compression makes files about a tenth the size of CD audio, and at 192 kbps or more most people can't hear the difference. Every device that plays music plays MP3.
What opens MP3 files
Everything: phones, computers, car stereos, smart speakers, browsers, and every music player and audio editor.
FAQ
Questions, answered
Is the MP3 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 MP3 to?
WAV, OGG, Opus, FLAC, M4A, AAC, and AIFF. Pick the format after adding your file.
What can I convert to MP3?
MP4, MOV, WebM, MKV, M4V, TS, AVI, WMV, FLV, MPEG, 3GP, OGV, WAV, OGG, Opus, FLAC, M4A, AAC, WMA, AIFF, and AMR.
