Convert an MP3 to an uncompressed WAV file for editing software or hardware that needs it. In your browser, nothing uploaded.
Drop an audio file
or drop it here, or paste. Up to 500 MB per file.
Runs in your browser. Your files are not uploaded.
Formats: the format list shows only what this browser can encode. MP3 and FLAC use an encoder that downloads the first time you choose them. M4A (AAC) is not available in every Firefox version.
Memory: audio is decoded in full, about 23 MB per minute of 48 kHz stereo, so long recordings can be slow on phones. Files that would need more than about 1 GB once decoded (about 45 minutes of 48 kHz stereo, or 90 of mono) are refused before decoding.

Questions

No. WAV keeps exactly what the MP3 contained; it cannot bring back detail the MP3 removed.
WAV is not compressed, so it is often ten times the size of the MP3.
Some editors, samplers and devices work with WAV only, and it adds no further loss when edited.
