Why convert MP3 to WAV?
MP3 is a lossy compressed format — some audio detail is permanently removed during encoding. WAV stores uncompressed PCM data, making it ideal for audio editing, professional production, and situations where quality loss is unacceptable.
Is this converter safe?
Yes. All conversion happens entirely in your browser using the Web Audio API. No audio data is sent to any server.

Frequently asked questions
Will converting MP3 to WAV improve audio quality?
No. Converting a lossy MP3 to WAV restores the container format but cannot recover the audio data lost during MP3 encoding. The result is a larger file with the same perceived quality.
What sample rate will the WAV file have?
The converter preserves the original sample rate and channel count from the MP3 file. Most MP3s are 44.1 kHz stereo, so the WAV output will match.
Do I need to upload my audio files?
No. Decoding and encoding happen entirely in your browser using the Web Audio API. Nothing leaves your device.
