Frequently Asked Questions
Will I lose audio quality converting MP4 to MP3?
Most MP4 files already use AAC audio compression. Converting to MP3 involves re-encoding, which can introduce minimal quality loss. At 320kbps, the difference is negligible for most listeners.
Can I extract audio from YouTube downloads?
If you have a locally saved MP4 file, yes. This tool processes files on your device — it doesn't download from URLs.
What happens to the video data?
The video track is discarded entirely. Only the audio is extracted and converted to MP3. Your file size drops dramatically.
