Common use cases
Extracting a song from a music video
Drop the MP4, extract at 320kbps for maximum fidelity. Processing is local so your download stays on your device throughout.
Saving a lecture recording as audio
Convert a 2-hour lecture MP4 to MP3 at 128kbps (voice quality) to listen while commuting. Use the trim handles to skip setup and Q&A sections.
Extracting audio from a Zoom or Teams recording
Meeting recordings save as MP4. Convert to MP3 for easier storage or transcription. Because nothing uploads, confidential recordings never pass through a third-party server.
Privacy for sensitive video
Video files can contain faces, voices, and location data. Server-based converters retain files temporarily. sound-goods never transmits your video — the browser decodes it in memory and discards the video frames locally.
