What the tool does, how to run it, and what to expect from the result.
To convert MP3 to WAV, add a single MP3 file and export it as a WAV. The conversion is a one-step flow that produces a WAV file you can download immediately.
Because everything runs in your browser, the MP3 stays on your device and there is no upload. The v1 flow is intentionally single-file, so you convert one MP3 at a time.
Some editing and import workflows still prefer WAV even when the source started as MP3, because WAV is uncompressed and widely supported by audio software. Converting first keeps that compatibility step simple.
Keep in mind that WAV output is typically much larger than the original MP3, since it is far less compressed. That trade is usually worth it when a tool or workflow specifically expects WAV input.

Converting MP3 into WAV when compatibility matters more than file size
Short answers for the questions people usually have before trying a utility like this.
Yes. Converting an MP3 to WAV is completely free, with no signup.
No. The conversion and export stay in your browser, so your file is never uploaded to a server.
Usually yes. WAV output is typically much larger than MP3 because it is far less compressed.
The v1 flow is intentionally single-file, so you convert one MP3 to WAV at a time.
Yes. Because it runs in the browser, you can convert MP3 to WAV on a phone or tablet as well as a desktop.
No, and this is the common misunderstanding. The MP3 already threw data away, and the WAV stores what is left with perfect fidelity, artefacts included. You get a much bigger file that sounds identical.
For editing. WAV is lossless, so trimming, fading and merging do not each cost another round of MP3 degradation. Work in WAV, then encode back to MP3 once at the end.
Around ten times the MP3. WAV is uncompressed, so a three-minute stereo track lands near 30 MB whatever the MP3 weighed.
Not from MP3. That gives you the size of a master with the quality of a lossy copy: the worst of both. Archive the original source, not a decoded MP3.
As a format, yes: it is lossless. But a WAV made from an MP3 is not better than the MP3, because the loss already happened.
