This free converter turns WAV audio files into MP3 in seconds — the output format is already selected above, so just drop in your file and click Convert. The most common reason to convert WAV to MP3 is file size — WAV is uncompressed and huge, while MP3 is roughly 10× smaller and easy to share, upload, or store.
Files up to 200 MB are supported, with quality presets from Low to High. Your file is processed in a short-lived temporary file on our server and deleted the moment your converted audio is delivered — nothing is stored, and there's no sign-up or watermark.

Frequently asked questions
How do I convert WAV to MP3?
Drop your WAV file into the upload zone above, keep MP3 selected as the output format, choose a quality preset, and click Convert. Download the MP3 when it finishes.
Will converting WAV to MP3 lose quality?
MP3 is lossy, but at the High preset (320 kbps) the difference from the uncompressed WAV is inaudible to almost all listeners on almost all equipment.
Is there a file size limit?
Files up to 200 MB are supported — several hours of audio at typical bitrates.
Is my audio file stored on your servers?
No. Your file is processed in a temporary file that is deleted immediately after the converted audio is delivered to you.
