Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.
Some tools simply insist on WAV — hardware samplers, transcription suites, old editors. This decodes your MP3s to standard 16-bit PCM WAV entirely in the browser: drop the files, download WAVs, feed the tool that was complaining.
How it works
- Drop files anywhere on the page, click to browse, or paste with ⌘V.
- Pick a quality or preset — or set an exact target size and let the tool find it.
- Compress, compare before/after, and download — individually or as a ZIP.
A decode, not an upgrade
Treat this as unpacking: the WAV is the MP3’s content in a form every tool accepts, no better and no worse. Archiving losslessly only works from lossless sources — WAV to FLAC halves master sizes; going back the other way, WAV to MP3 makes the small share copy.
Frequently asked questions
Does WAV sound better than the MP3?
No — decoding cannot restore what MP3 encoding removed. The WAV holds exactly what the MP3 contained, just unpacked into raw samples that picky software accepts.
How much larger will it be?
Roughly 10 MB per stereo minute at 16-bit/44.1 kHz — about ten times a 192 kbps MP3. That is the price of raw samples; delete the WAV when the tool is done with it.
Why do editors want WAV at all?
Editing decodes audio anyway, and working from WAV avoids generation loss when saving: cut and mix in WAV, then export a lossy copy once at the end.
Is it private?
Yes. The audio is decoded and re-encoded entirely in your browser — recordings never leave your device, and the server does nothing but deliver this page. Voice memos, interviews, demos: none of it is uploaded anywhere. Want proof? Run one file through, switch your connection off, and run another — it still works.
