MP3 (.mp3) · Max 20 MB
The converter defaults to the highest practical bitrate for WAV. Since WAV is lossless, every sample is preserved exactly. No encoder settings to worry about.
Garbage in, garbage out. The output quality depends on your source. A 128kbps MP3 file won't sound better in WAV. Start with the best source available.
AudioUtils processes everything locally using WebAssembly. The encoder runs at near-native speed. A 10-minute file converts in seconds with maximum quality settings.
Frequently Asked Questions
Does converting MP3 to WAV improve quality?
No. MP3 is lossy — once compressed, the discarded data can't be recovered. Converting to WAV gives you an uncompressed container, but the audio quality stays the same as the source MP3. It's useful for compatibility with audio editors that require WAV.
How long does MP3 to WAV conversion take?
Seconds. The conversion runs entirely in your browser using WebAssembly. No upload, no server processing, no waiting.
Will the WAV file be larger than the MP3?
Yes, significantly. A 5MB MP3 file typically becomes a 50MB WAV file. WAV is uncompressed, so file sizes are roughly 10x larger.
Is this converter free?
Yes. Free users get 5 conversions per day with a 20MB file size limit. Need more? Upgrade to Pro for unlimited conversions.
