About the MP3 Converter
MP3 is the most widely supported audio format, compatible with virtually every device, app, and platform. Convert M4A or AAC files recorded on iPhone, lossless WAV or FLAC files, and other audio formats to MP3 for universal playback. All conversion runs entirely in your browser using the Web Audio API — files are never sent to a server. Multiple files can be converted in one session.
