Free Online Audio Converter — MP3 & WAV

Convert audio files between MP3 and WAV formats instantly. Whether you need a compressed MP3 for streaming or a lossless WAV for professional audio work, this tool handles the conversion server-side using ffmpeg — no software installation required.

When to Use MP3 vs WAV

  • MP3 — Compressed format ideal for web playback, podcasts, music streaming, and mobile apps. Smaller file size at the cost of some audio data.
  • WAV — Uncompressed lossless format preferred for audio editing, broadcast, and archiving where quality must be preserved.

Bitrate Options

For MP3 output, choose from 128k (compact), 192k (balanced, default), or 320k (high quality). Higher bitrates produce better audio but larger files.

Frequently Asked Questions

What audio formats can I convert?

You can convert between MP3 and WAV formats. Upload an MP3 to get a WAV, or upload a WAV to get a compressed MP3 at your chosen bitrate.

What bitrate should I choose for MP3 conversion?

192k is the recommended default for a good balance of quality and file size. Use 128k for smaller files (podcasts, voice) or 320k for music where audio quality is critical.

Is there a file size limit for audio conversion?

File size limits depend on the server configuration. For best results, use files under 50MB. Large files may take longer to process.

Does the converter lose audio quality?

WAV is lossless so converting MP3 to WAV does not improve the original quality — it just changes the container. Converting WAV to MP3 applies compression, which reduces file size but may slightly reduce audio fidelity depending on the bitrate chosen.
