Audio Converters

MP3, WAV, M4A, FLAC and OGG — convert and extract audio. · 8 tools

Voice memos in M4A, studio exports in WAV, downloads in FLAC or OGG and lectures recorded as video: these tools turn them into the format your player, car, transcription service or editor wants. MP3 is the universal target; WAV and FLAC are the lossless ones.

Decoding uses your browser’s media engine and encoding runs as WebAssembly, so a two-hour recording converts on your device without uploading. Only rare codecs fall back to the server.

How to choose

For compatibility
MP3 at 192 kbps plays on everything and sounds fine for music; 128 kbps is enough for speech.
For editing
WAV is what editors and DAWs work in. Convert MP3 to WAV before cutting, and back to MP3 when sharing.
For archiving
FLAC is lossless at half the size of WAV. Keep FLAC or WAV masters and make MP3 copies.
