Frequently asked questions
Can I download audio from a YouTube or social media link?
No. This tool accepts video files from your device, not video URLs. Only process files you own or have permission to use.
Why is no audio output available?
The video may lack an audio track, be damaged or use an unsupported codec. Output is encoded as MP3, not copied identically from the source track.
