MP3 to WAV and back. The file stays on this computer.

The Chrome Web Store listing is not public yet. Mac and Windows tiles are placeholders until those stores publish the item.

Both directions
MP3 becomes uncompressed WAV (8, 16, 24, or 32-bit float). WAV becomes MP3 at 128, 192, 256, or 320 kbps. Peak normalize is optional and will not clip.
Queue and preview
Drop several files. Each row shows duration, source size, and an estimated output size. Preview uses the current settings and does not spend a conversion.
