Free WAV to MP3 Converter — Compress Audio In-Browser

Convert WAV to MP3 instantly without losing your privacy. Perfect for shrinking large recording files, preparing audio for upload, or making podcasts and music compatible with any device or player.

How It Works

Upload a WAV file, choose your MP3 bitrate (128–320 kbps) and sample rate, then click Convert to MP3. The audio is decoded and re-encoded locally with a pure-JavaScript LAME encoder — nothing is uploaded.

Tips for Best Results

  1. 1. Use 128 kbps for voice, podcasts, and ringtones to keep files small.
  2. 2. Use 192–320 kbps for music to preserve higher fidelity.
  3. 3. Choose 44.1 kHz or 48 kHz for maximum compatibility with players and editors.
  4. 4. All processing happens in your browser — no server uploads, no file size limits.

All processing happens locally in your browser — your data never leaves your device.

Frequently Asked Questions About WAV to MP3

Q1How do I convert a WAV file to MP3?

Upload your WAV file, pick a bitrate (128–320 kbps) and sample rate, then click Convert to MP3. Encoding runs entirely in your browser using a pure-JavaScript LAME encoder — no upload required.

Q2What bitrate should I choose?

128 kbps is the standard choice for speech and podcast audio and keeps file sizes small. 192–320 kbps produces higher fidelity for music. Larger bitrates mean bigger MP3 files but better sound quality.

Q3Are my audio files uploaded to a server?

No. The WAV file is decoded and encoded 100% locally inside your web browser. Nothing is transmitted, so your audio stays completely private.

Q4Can I convert non-standard sample rates?

Yes. If your WAV uses a sample rate MP3 does not support, the audio is automatically resampled to the nearest MP3-compatible rate (such as 44.1 kHz or 48 kHz).
