動画から音声を削除 — 無料オンラインミュート を選ぶ理由

  • Clean silent output

    The audio track is completely removed, not just muted. File size drops accordingly.

  • Files stay local

    FFmpeg.wasm runs in your browser. Your video is never uploaded to a server.

    We stream-copy the video track (no re-encoding) — the output is bit-identical minus the audio.

よくある質問

Does removing audio reduce video quality?
No. We stream-copy the video track without re-encoding, so the output is bit-identical to the source minus the audio track. Lossless.
Is this the same as muting the audio?
No — the audio is fully removed (the file no longer contains an audio track). File size shrinks slightly and players will not try to play silence.
What formats are supported?
Input: MP4, MOV, AVI, MKV, WebM, FLV, WMV. Output: MP4 (the universal web-friendly default).
Are my files uploaded?
No. Processing runs locally in your browser via FFmpeg.wasm.
Can I remove just a portion of audio?
Not with this tool — it removes the entire audio track. For partial muting, use a dedicated video editor after removing-then-re-adding the trimmed audio.
Does it work for very large files?
Files up to 2 GB are reliable in modern browsers. Larger files may exceed browser memory — split first if needed.
