Common Use Cases
- Extract audio from video: Drop an MP4/MOV file and select “Audio → MP3” to extract background music or voice recordings.
- Convert video formats: MOV → MP4 for broader device compatibility; MP4 → WebM for web embedding.
- Audio transcoding: WAV → MP3 shrinks lossless audio roughly 10×; M4A → MP3 improves device compatibility.
⚠️ Performance note: Large video files (over 500 MB) may process slowly. Consider compressing or splitting large files first. ffmpeg.wasm performance may be limited on mobile devices.
✅ Privacy advantage: All conversions run locally. Video files are never uploaded to any server, making this ideal for private or sensitive content.
