Convert audio to WAV

With Convert audio to WAV, podcasters, musicians and audio editors can prepare a track during an edit. Turn MP3, M4A, OGG or FLAC into WAV without uploading the file.

Turn MP3, M4A, OGG or FLAC into WAV without uploading the file. The tool is free in your browser and shows the result without asking you to create an account.

How to use

Select an audio file from your device; the interface lists MP3, M4A, OGG, FLAC and WAV as examples.
Pick a sample rate: keep the file setting, 48,000 Hz, 44,100 Hz or 22,050 Hz.
Choose the channel option: keep, mono or stereo, depending on how you will use the track.
Start the conversion, then listen to the WAV and download it when it is ready.

Example

For instance, convert an interview recorded in M4A when your editing software prefers WAV. Keep the original sample rate and channel layout to avoid an unnecessary change, then check that the duration and the voices sound the same as before.

Limits and formats

This converter handles one file at a time and does not trim, join or clean up the audio.
The interface states a total duration limit of 15 minutes, so longer recordings need to be shortened first.
A WAV file is much larger than a compressed MP3 or M4A, so make sure you have enough free space.
Converting cannot restore quality that was already lost in the original compressed file.

Where processing happens

The conversion happens entirely in your browser. Your audio file is decoded on your device and the WAV is created locally. Nothing is uploaded, and no account is needed.

Frequently asked questions

Why convert to WAV instead of keeping the original MP3?

WAV is uncompressed, which many editors and CD tools handle directly. It does not bring back details lost in the MP3, but it avoids another layer of compression while you edit or export the track.

Which sample rate should I pick for a podcast or music file?

Keeping the file setting is usually the safest choice. For common delivery, 44,100 Hz or 48,000 Hz are familiar options. A lower rate creates a smaller file but may soften high frequencies.

Can I convert a whole folder of songs at once?

No, this tool is designed for a single audio file per run. If you have several tracks, convert them one by one and then import the WAV files into your editor or player.
