WAV to MP3 Converter — Free, Online, No Upload
Convert your WAV audio files to much smaller MP3s, right in your browser.
Drag and drop your files here, or click to browse.
How it works
A WAV file is uncompressed: one minute of music weighs about 10 MB. MP3 brings it down to about 1.5 MB with near-identical sound. Choose your WAV files, start the conversion and download the MP3s (192 kbps, encoded with the LAME engine).
What quality will I get?
192 kbps is a very good balance: hard to tell from the original on everyday equipment, in a file about 7 times smaller. MP3 is still lossy, so keep your WAV if you plan to edit it further.
Is there a size limit?
200 MB per file. The engine loads once (a few seconds), then conversions run back to back with no data sent anywhere.
Your audio files never leave your device: the conversion runs entirely in your browser.
