FAQs about Converting Video to Audio

Should I convert to MP3 or FLAC?

MP3 if you are going to listen or share it; FLAC if you plan to edit it or want to archive the original quality. FLAC files are roughly two to three times the size of a high-bitrate MP3.

Can I convert a YouTube video to MP3?

Only where the platform's terms and your local law allow it. For content you own, download the file first and then convert it locally with VLC — the process is identical for any MP4.

Yes — Video Converter Ultimate has a batch queue, and free online converters cap batch jobs aggressively on their free tiers.
