Free audio to WAV converter
Convert audio files directly in your browser, completely for free, with no uploads or server processing. All conversions stay on your device.
How it works
FFmpeg runs entirely in your browser to re-encode your audio files. Larger files may take longer depending on your device.
For best results, keep your browser open while the conversion is running.

Frequently asked questions
Which audio formats can I convert?
You can convert between MP3, WAV, FLAC, M4A, AAC, and OGG in any direction, and convert several files at once.
Will converting to a lossless format improve quality?
No. Converting an MP3 to WAV or FLAC keeps exactly the quality of the MP3; it only makes the file bigger. Lossless formats are useful when software needs them, or to avoid losing more quality in later edits.
Is this tool free?
Yes. It is completely free, with no account, no watermark, and no limit on how many files you process.
Are my files uploaded anywhere?
No. Your audio is processed entirely in your browser and never leaves your device.
