What does Remove Audio from Video do?
Tubelexity removes an entire audio stream, mutes selected time ranges or replaces the original track with local audio. Complete removal stream-copies compatible video to avoid unnecessary quality loss. Range muting and replacement re-encode only audio where possible, then produce one local MP4 or WebM download.

- Replacement audio is encoded for the output container.
- Some source containers cannot be stream-copied into the selected output.
- Long WAV replacement tracks can use substantial memory.
How local processing works
Processing runs locally in your browser with FFmpeg.wasm. The media engine is downloaded on first use, but your media is not sent to Tubelexity or a processing server.
Frequently asked questions
Can I remove audio without reducing video quality?
Complete removal uses video stream copy when the selected container supports the source stream.
Can I mute only part of a video?
Yes. Add multiple ranges; overlaps are merged before export.
Can I replace the original audio?
Yes. Choose local audio, then cut, loop or pad it to the video duration.
Does Tubelexity upload my video?
No. Media processing stays in the browser.
What happens if the video already has no audio?
The tool reports that it already has no audio track and avoids a misleading removal job.
