MP3 to WAV Converter

Because some tools accept nothing else. Hardware samplers and CD-burning software often ask for WAV. Editing a WAV also avoids another round of MP3 compression each time you save the file.

Around seven times bigger than a typical 192 kbps MP3. Stereo WAV at 44.1 kHz takes about 10.6 MB per minute whatever the MP3 bitrate was, so a four-minute song grows from under 6 MB to about 42 MB.

The WAV is 16-bit, at the same sample rate as the MP3, which is usually 44.1 kHz. Neither setting can be changed here. If a phone system or another device needs something specific, such as 8 kHz mono, resample the file in another program.

WAV stores audio uncompressed, sample by sample. MP3 compresses it by discarding sounds the ear is least likely to notice, so a 128 kbps MP3 is about a tenth of the size of the WAV. MP3 is fine for listening. WAV is the safer format for editing.

Yes, if the MP3 is 44.1 kHz stereo, as almost every music MP3 is. The WAV is then 16-bit, 44.1 kHz stereo, which is exactly the audio CD format, so burning software writes it without converting it again.

No. The conversion runs on our server, and all you need is a browser on Windows, Mac, Linux, Android or iPhone. There is no installer, no account and no watermark added to the audio.

Yes, 1 GB for the MP3 you upload. That is enough for any song, podcast episode or long DJ mix. The WAV you download will be several times larger than the upload.

Uploads travel over HTTPS. The source file and the finished WAV are both deleted from our servers within minutes of the conversion, and neither is shared with anyone.
