Quality note
Conversion cannot recover information already removed from a lossy source. For archival workflows, prefer a lossless target such as FLAC or uncompressed WAV when appropriate; for compact playback, MP3, AAC and Opus are common choices.
Frequently asked questions
Does video-to-audio conversion upload the video?
No. The project is positioned as a local Windows converter, so the conversion workflow does not require uploading the source media to a web service.
Can I convert an already-compressed source to lossless audio?
You can encode it to a lossless container, but that does not restore detail lost in the original lossy encoding.
