About the Audio Converter

The Audio Converter transforms audio files between popular formats — MP3, WAV, AAC, FLAC, OGG, and more. Upload any audio file and convert it to the format your device, software, or platform needs. Choose quality settings to balance file size against audio fidelity for your specific use case.

How to use it

  1. Upload your audio file (MP3, WAV, FLAC, AAC, OGG, M4A).
  2. Select the target output format.
  3. Choose quality settings (bitrate for MP3, sample rate, channels).
  4. Download the converted audio file.

Formula & methodology

Audio file size: (sample_rate * bit_depth * channels * duration) / 8 bytes. Example: CD quality WAV = 44100 Hz * 16 bit * 2 channels * 60 seconds / 8 = 10.1 MB/min. MP3 compression: 128 kbps = 1 MB/min (10:1 compression). AAC quality equivalent: 128 kbps AAC = 192 kbps MP3 in perceived quality. FLAC: lossless, typically 50-60% of WAV size.

Common use cases

  • Converting FLAC audio to MP3 for devices with storage limits
  • Converting WAV files to AAC for Apple device compatibility
  • Creating high-quality FLAC archives from lossy source files
  • Converting audio for upload to streaming platforms
  • Reducing audio file size for podcast or web audio embedding

Frequently asked questions

No — converting a lossy format (MP3) to a lossless format (WAV) does not restore lost audio data. The original compression permanently removed audio information. Converting MP3 to WAV just wraps the same data in a larger container — the quality remains that of the original MP3. Always keep lossless originals (WAV, FLAC) as your archive format. Convert to lossy formats only for distribution.
128 kbps: acceptable for casual listening, significantly smaller files. 192 kbps: good quality, most people cannot distinguish from higher rates. 256 kbps: very good quality, recommended for music you care about. 320 kbps: maximum MP3 quality, virtually indistinguishable from CD for most people. For podcasts/speech: 96 kbps is sufficient. For music: 192 kbps is the sweet spot. FLAC is preferred for archiving — use it when storage is not a constraint.
