Frequently Asked Questions

Common questions about the free online audio to wav converter.

Choose any audio file your browser can play, then click Convert and download WAV to save the decoded PCM as a WAV file.
Anything the browser can decode, which usually means MP3, M4A, AAC, OGG, Opus, FLAC and WAV itself.
No. WAV stores uncompressed 16-bit PCM, so the file is larger than the original MP3 but keeps the full quality.
No. Browsers have no MP3 encoder, so this page only converts other formats to WAV and never the other way around.
Uncompressed PCM needs far more space than a compressed format such as MP3. Expect roughly ten megabytes per minute of stereo audio.
It averages the left and right channels into one channel, which halves the file size and suits speech recordings.
