Free Online Audio Converter
Convert audio between all the popular formats — MP3, WAV, FLAC, M4A, AAC, OGG and OPUS — without installing any software. Everything runs in your browser using WebAssembly, so your files are never uploaded to a server. That keeps your audio private and means there are no file-size caps beyond what your device can handle.
Whether you need to turn a FLAC into MP3 for your phone, convert WAV to MP3 to save space, or get an M4A to MP3 for an app that won't play Apple audio, this converter does it in a couple of clicks — and lets you choose the bitrate for the perfect balance of quality and file size.
