MP3 → WAV
As a rough guide, files over 1GB are more likely to fail due to device memory limits.

Why convert MP3 to WAV
Some video editors, DAWs and CD-burning tools require WAV for import or export and either reject MP3 or behave unreliably with it. Converting the container to WAV first makes the file easier to work with in those tools.

How to use it
(1) The output format is already set to WAV on this page. Drag and drop your MP3 file onto the drop zone, or click it to choose one. (2) WAV is uncompressed, so there's no bitrate to set — you can optionally set a sample rate (keep as-is, 44.1kHz, or 48kHz). (3) Press 'Convert to WAV'; a download button appears once it finishes.

This won't improve the sound quality
MP3 is a lossy format, so some information is already gone by the time you have the MP3 file. Converting it to WAV doesn't bring that information back — it only repackages the audio into an uncompressed container. If you need a truly lossless file, use the original pre-compression source (WAV or FLAC) if you still have it.

FAQ
- Does converting to WAV improve quality?
- No. The MP3 has already lost information through lossy compression; converting to WAV doesn't restore it — it just changes the container format.
- Why would I need to convert MP3 to WAV at all?
- Some editing software, CD-burning tools and hardware either can't read MP3 directly or expect WAV. Converting gives you a format those tools can use.
- How much bigger does the file get?
- It grows because WAV is uncompressed — as a rough guide, a 192kbps MP3 converted to WAV ends up roughly 7–8 times larger.
- Is my file uploaded anywhere?
- No. Conversion happens entirely in your browser; files are never sent to a server.
