What is a WAV file?

WAV – WAV audio. WAV is uncompressed audio from Microsoft and IBM: every sample is kept, so files are large (about 10 MB a minute) and editing programs love them. Converting makes a new file: the sound is decoded and written again, so converting from a lossy format never brings back what was lost.

Frequently asked questions

Is converting WAV to WMA free?

Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.

Are my WAV files uploaded anywhere?

This conversion runs on our server, because converting audio needs ffmpeg, which does not run in a browser. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion. The server has no internet access while it works on your file.

How large can the WAV file be?

Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.

Will the WMA look the same as the WAV?

It sounds very close: the sound is encoded again as WMA at a fixed quality, so a little detail is lost, and tags such as title and artist are kept where WMA has room for them.

Can I convert several WAV files at once?

Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.

How long does converting WAV to WMA take?

In our tests a one-hour WAV recording became an M4A file in about 46 seconds. A song of a few minutes takes a few seconds, and most conversions cost a single credit.
