# Convert WAV to MP3 Free

Convert WAV audio files to high-fidelity MP3 with genuine local LAME encoding. Free, choose your bitrate, and nothing is uploaded to a server.

## What is WAV to MP3 converter?

Convert gigabytes of studio WAV recordings into lightweight MP3 tracks for easy listening on phones, cars, and media players. Our engine uses the industry-standard LAME encoder compiled to WebAssembly for immaculate frequency response.

## How to use WAV to MP3 converter

1. **Add your file or input** — Choose a supported file, drag it onto the upload area, or type/paste the data this tool works with.
2. **Adjust the options** — Pick the output format, quality, size or other settings the tool offers. Defaults work well for most files.
3. **Process and download** — Run the tool and save the result. Processing happens in your browser, so nothing is uploaded to a server.

## Frequently asked questions

### How much smaller will an MP3 be compared to a WAV file?

A standard 16-bit 44.1kHz stereo WAV file runs at 1,411 kbps (~10MB/min). Converting to a 192 kbps MP3 reduces file size by approximately 86% down to ~1.4MB/min.

### What LAME bitrate is recommended for musical tracks?

We recommend 256 kbps or 320 kbps constant bitrate (CBR) for music to preserve sparkling high frequencies and transient drum hits.

### Does this tool preserve audio channel balance?

Yes. Left and right stereo channels are decoded and encoded with full stereo imaging intact.
