Convert MP3 to WAV
This tool decodes an MP3 and writes it out as an uncompressed WAV file, in your browser. The MP3 is never uploaded: it is decoded and written as 16 bit PCM at its original sample rate and channel count, on your device. If your browser cannot decode the MP3, GRID16 says so instead of producing a broken file.

Questions
- Is my file uploaded?
- No. The file stays on your device: it is read and converted in your browser.
- What are the limits?
- Up to 100 MB and 10 minutes, free of charge.
- Why is the WAV so much larger than the MP3?
- A WAV stores raw, uncompressed samples, while an MP3 compresses them. The WAV is four to eleven times the size of its source MP3, depending on the bit rate of the MP3.
- Does the WAV sound better than the MP3?
- No. The MP3 already lost detail when it was compressed, and writing it out as WAV does not bring that detail back. A WAV is only easier for other software to work with.
- What bit depth and sample rate does the WAV get?
- 16 bit PCM, at the sample rate and channel count of the source MP3. GRID16 never resamples or changes the channel count.
