[WAV to MP3](https://edesy.in/tools/wav-to-mp3) converts uncompressed WAV recordings to MP3 in your browser. Nothing is uploaded.

## How to Use

1. Click **Load Audio Engine**. It downloads once and takes a few seconds.
2. Add one or more WAV files (MP3 is already selected as the output) and click **Convert**.
3. Check the size before and after, then download each MP3.

## How much smaller?

| Length | WAV (44.1 kHz, 16-bit stereo) | MP3 (128 kbps) |
|---|---|---|
| 1 minute | about 10 MB | about 1 MB |
| 10 minutes | about 100 MB | about 10 MB |
| 1 hour | about 600 MB | about 60 MB |

## Things to know

- MP3 removes some detail. For speech and everyday listening you won't notice; keep the WAV if you will edit or master the audio.
- To shrink the MP3 further, use the [Audio Compressor](https://edesy.in/tools/audio-compressor).
