How to convert MP3 to WAV

- Download. Each file appears in the list when it is ready. Download them one by one, or all together with Download all.
Why convert MP3 to WAV?
Audio editors, DJ software, video editors and some hardware players work best with WAV. Converting MP3 to WAV gives you an uncompressed file that any program can open and edit without decoding.
When to keep the MP3
Keep the MP3 for listening and storing: it is about ten times smaller than the WAV and sounds exactly the same.
Tips for the best result
- The WAV is 16-bit PCM, the standard CD-quality format.
- Expect around 10MB per minute of stereo audio.
- Converting does not improve sound quality; it only removes the compression step for editing.
Common problems and fixes
- The WAV is huge.
- WAV is uncompressed. That is normal.
- The sound is not better than the MP3.
- Detail removed when the MP3 was made cannot be restored.

Frequently asked questions
Does MP3 to WAV improve quality?
No. The sound stays exactly as good as the MP3, stored in a bigger, uncompressed file.
Why do editors prefer WAV?
WAV needs no decoding and has no encoder delay, so cuts and loops are sample-accurate.
How do I convert MP3 to WAV?
Click Select File or drop your MP3 file onto the upload box. The converted WAV appears in the list below with a download button. You can add many files at once and download them together as a ZIP.
Is it really free?
Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Are my files stored?
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
Will quality drop?
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
How this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
