FAQAudio conversion questions
Does this audio converter upload my MP3 or WAV files?
No. The page decodes and converts supported audio files in the browser, so normal conversion work stays on your device.
Can I convert MP3 to WAV?
Yes. Add an MP3 file and keep the output mode on Auto or choose WAV to create a 16-bit PCM WAV file.
Can I convert WAV to MP3?
Yes. Add a WAV file, choose Auto or MP3 output, then pick the MP3 bitrate before converting.
Will metadata and album art be preserved?
No. Browser-side conversion focuses on the audio stream, so tags, embedded artwork, cue markers, and other metadata may not be copied.
