FAQ
Specific answers for this tool, not generic converter copy.
Does this MP3 to WAV converter upload my file?
No. The selected MP3 is processed in your browser tab and is not sent to a conversion server.
Why is the WAV file larger than my MP3?
WAV is usually uncompressed PCM audio, so the result is often much larger than a compressed MP3 file.
Can I use this on a phone?
Small files can work on modern mobile browsers, but desktop browsers are more reliable for long recordings.
