MP3 (.mp3) · Max 20 MB
MP3 already discarded some audio data during its initial compression. Converting to WAV wraps the remaining audio in a lossless container. No additional quality is lost.
This is useful when your editing tools require WAV input. You get compatibility without a second round of lossy compression.
For the best results, always start from the highest quality source you have. If you have the original uncompressed recording, convert that instead.
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.
