Convert any audio to WAV online

WAV is uncompressed, lossless PCM audio — exactly what you want for editing, mastering and professional work where every detail matters. This free tool converts MP3, M4A, FLAC, OGG, OPUS and more to WAV in your browser, giving you clean CD-quality audio ready for a DAW or sampler.

Lossless quality for editing

Because WAV stores raw audio with no compression, it preserves the full signal and avoids stacking lossy artefacts when you re-edit. That makes it the standard for recording, sound design and audio software, at the cost of a larger file than MP3.

Runs in your browser, files stay private

Conversion happens entirely on your device with WebAssembly — nothing is uploaded. No sign-up, no watermark and no file limit, so you can prepare as many WAV files as your project needs.

Frequently asked questions

How do I convert audio to WAV?

Open the tool, drop in your MP3, M4A, FLAC, OGG or OPUS file, keep WAV as the output and click convert. The WAV is produced in your browser and downloads immediately.

Why convert to WAV?

WAV is uncompressed and lossless, so it is the best format for editing, mastering and importing into a DAW — it keeps full quality and avoids the artefacts that build up when re-encoding lossy files.

Is the audio to WAV converter free?

Yes, completely free with no sign-up, no watermark and no limit on the number or size of files you convert.

Will converting MP3 to WAV improve quality?

No — WAV cannot restore detail already lost by MP3 compression, but it stops further quality loss during editing, which is why WAV is preferred as a working format.

Are my audio files uploaded to a server?

No. All processing runs locally in your browser, so your audio never leaves your device.
