What WAV to MP3 Converter does
Shrink WAV recordings into MP3 files at the bitrate you choose, in your browser.
Most media work stays in browser memory. Heavy converters lazy-load a local WebAssembly engine only after processing starts. For WAV to MP3 Converter, the operation is specifically to shrink WAV recordings into MP3 files at the bitrate you choose, in your browser.
Worked example
A 3-minute song.wav at CD quality (44.1 kHz, 16-bit stereo, about 31MB) becomes song.mp3 of about 7MB at 320 kbps or 4.3MB at 192 kbps, a fraction of the size with little audible difference.
When WAV to MP3 Converter is the right tool
- Shrinking recordings from a DAW or field recorder for sharing.
- Fitting more music on a phone or USB stick.
How to verify the result
Play the beginning and end of the output, confirm duration and format, and check lip-sync or audio quality where relevant. The final WAV to MP3 Converter output should visibly match this goal: Shrink WAV recordings into MP3 files at the bitrate you choose, in your browser.
Important limitations
Large media jobs can be slow or run out of browser memory. Keep the tab open and use desktop software for very large or production-critical files. This matters here because WAV to MP3 Converter is designed to shrink WAV recordings into MP3 files at the bitrate you choose, in your browser, not to repair unrelated source problems.

Frequently asked questions
What bitrate should I use?
192 kbps is a good balance for music and 128 kbps is plenty for speech and podcasts. Use 320 kbps if you want the most transparent result.
How much smaller will the MP3 be?
CD-quality WAV uses about 10MB per minute. MP3 at 192 kbps uses about 1.4MB per minute, roughly seven times smaller.
Are tags kept?
Tags stored in the WAV file, such as title and artist, are copied into the MP3 where MP3 supports them.
Is there a size limit?
The first conversion downloads about 32 MB of processing code. Files are processed one at a time on your device and kept in memory, so very long recordings need a device with plenty of RAM.
Is my audio uploaded?
No. The conversion runs with FFmpeg in your browser.
