These sections explain the job in plain language and set expectations for what the tool should do well.
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.
Short answers for the questions people usually have before trying a utility like this.
