Choose the right audio format
- MP3: the most compatible format for phones, cars and players.
- M4A (AAC): very good quality at small sizes; standard on Apple devices.
- WAV: uncompressed; best for editing, but files are large.
- FLAC: lossless compression; full quality at about half the size of WAV.
- OGG and OPUS: efficient open formats; OPUS is excellent for voice.
Common conversions

Quality and privacy
Choose 128 kbps for speech, 192 kbps for music or 320 kbps for the best quality. Converting a lossy file such as MP3 to WAV or FLAC does not restore lost quality; it only prevents further loss. Files are converted in your browser with ffmpeg and are never uploaded.
