WAV to MP3
Upload a WAV file and convert it to a compressed, universally compatible MP3 — free and processed entirely in your browser.
About the WAV to MP3 Converter
WAV files preserve audio at full, uncompressed quality — which also makes them huge compared to a compressed format. Converting to MP3 shrinks the file dramatically while staying compatible with virtually every device, app, and media player.
This tool decodes your WAV file and re-encodes it to MP3 entirely in your browser, using the same MP3 encoder that powers our other audio tools. Nothing is uploaded to a server.

Frequently Asked Questions
How much smaller will my file be?
Typically 5-10x smaller than the original WAV, since WAV stores audio completely uncompressed — the exact ratio depends on your WAV's original sample rate and bit depth.
Will I notice a quality difference?
For most listening — music, voice, podcasts — a standard MP3 export is effectively indistinguishable from the source WAV, even though it's technically lossy.
Is there a file size or length limit?
No hard limit, but very long or high-resolution WAV files take longer since everything runs on your own device's processing power.
Is my audio file uploaded anywhere?
No. Decoding and encoding both happen entirely in your browser.
