video audio extractor는 무엇에 적합합니까?
Audio extraction saves the soundtrack from courses, meetings, or media clips as a separate file. The tool runs ffmpeg.wasm locally in the browser, and videos are not uploaded.
M4A is smaller and easier to share; WAV is better for later editing but much larger.
지원되는 형식: MP4, MOV, WebM, AVI; 단일 파일 제한: 500MB.
