Muting drops the audio stream entirely: smaller files, no accidental background chatter, and platforms treat it as safe-for-feed. Lowering volume keeps the stream bytes and the risk.
No — the video stream copies untouched while only the audio track is removed. A 100 MB clip returns at ~95 MB with identical frames.
This tool mutes the whole file in one pass. For partial mutes, trim the segment first, mute it, then merge the parts back together.
No — muting runs locally in your browser with FFmpeg WASM. Only the final save touches the network — downloads are unlimited.
