Good to know

Converting a lossy file to a lossless format does not restore information already removed by compression.
Use WAV or FLAC when sound quality matters; use MP3 or OGG when a smaller file is more important.
Your source files stay in the browser and are not uploaded to an Örbital server.

Frequently asked questions

Are my files uploaded?

No. Conversion happens locally in your browser and the source audio stays on your device.

Does converting MP3 to WAV improve quality?

No. WAV can prevent further lossy compression, but it cannot recreate audio information already removed from the MP3.

Which format should I use for music production?

WAV is the most broadly compatible uncompressed choice. FLAC is useful when you want lossless quality with a smaller file.

Which format is best for sharing?

MP3 is usually the safest choice for compatibility, while OGG can provide efficient compressed audio in supported players.
