How to convert MP3 to WAV
To change MP3 to WAV, add one MP3 file, then download the WAV file. The converter decodes the MP3 and writes uncompressed PCM audio, running in your browser, so the file is not uploaded.
Why convert MP3 to WAV
Some audio editors, DAWs and older hardware expect uncompressed WAV rather than a compressed MP3. Converting first can avoid an import error or a workflow step that only accepts WAV. This free MP3 to WAV converter handles that conversion without an account.
What converting to WAV does not do
MP3 is a lossy format: detail removed when the MP3 was first encoded is not restored by converting to WAV. The WAV file is larger and uncompressed from this point forward, but it cannot recover the original, pre-MP3 audio.
Need a transcript instead of a WAV?
You can send the original MP3 to MP3 transcription without converting it here first. Transcription is separate from this free local converter: it uploads prepared audio and requires an account. Speaker labels are available when selected. Eligible personal accounts can receive 30 free minutes after card verification.

Frequently asked questions
Is this MP3 to WAV converter free?
Yes. Converting one MP3 file to WAV in your browser is free and needs no account. Transcription is a separate service with its own account and minute pricing.
How do I convert MP3 to WAV?
Add your MP3 file to the tool above, wait for the conversion to finish, and download the WAV. There is no bitrate choice: WAV is uncompressed.
Does converting MP3 to WAV upload my file?
No. The converter processes the MP3 in your browser and downloads the WAV to your device. Choosing transcription separately uploads prepared audio.
Will converting to WAV improve the sound quality?
No. MP3 is a lossy format, so detail removed during MP3 encoding is not restored by converting to WAV. WAV only stops further lossy compression from this point on.
Why convert MP3 to WAV at all?
Some audio editors, DAWs and hardware expect uncompressed WAV rather than a compressed MP3, so converting first can avoid an import or processing error.
Can I transcribe the MP3 instead?
Yes, through the separate Hushscript transcription service, which uploads prepared audio and requires an account. Speaker labels are available when selected.
