FAQ

Will converting MP3 to WAV improve the sound quality?

Converting MP3 to WAV expands compressed audio into uncompressed PCM format. While it cannot recreate audio details lost during original MP3 compression, it generates a clean WAV file ideal for editing in DAWs and DJ software.

Can I add album cover art and custom metadata?

Yes! You can upload an image, crop it using our built-in crop tool, and edit ID3 metadata including Artist, Title, Year, Label, BPM, Musical Key, Remixer, and Lyrics.

Are my audio files uploaded to a server?

No. All conversion and metadata processing happen entirely inside your web browser via local CPU WebAssembly technology.
