--- title: "MP3 to WAV Converter — For Editors & DAWs | Compress Pro" description: "Convert MP3 to WAV in your browser — uncompressed PCM that samplers, DAWs and legacy tools accept without complaint. Free, private, no uploads ever." canonical: https://compress-pro.com/mp3-to-wav --- # Convert MP3 to WAV. > Decode MP3s into clean WAV PCM for editors and samplers. 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. **No uploads · No ads · Free & open source.** ## How it works 1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V. 2. Pick a quality or preset — or set an exact target size and let the tool find it. 3. 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](https://compress-pro.com/wav-to-flac) halves master sizes; going back the other way, [WAV to MP3](https://compress-pro.com/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. ## Related tools - [Convert WAV to MP3](https://compress-pro.com/wav-to-mp3) - [Convert MP4 to WAV](https://compress-pro.com/mp4-to-wav) - [Compress & Convert audio](https://compress-pro.com/compress-audio) --- Part of [Compress Pro](https://compress-pro.com/) — every tool page has a markdown twin at `.md`.
