Frequently asked questions
How do I convert MP3 to WAV?
Drop your MP3 file into the upload zone above, keep WAV selected as the output format, choose a quality preset, and click Convert. Download the WAV when it finishes.
Will converting MP3 to WAV lose quality?
No further quality is lost — WAV is lossless, so the conversion preserves exactly what is in the MP3. It cannot restore detail the original MP3 compression removed, though.
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.
