Remove audio from a video

A video file holds separate video and audio tracks. This tool copies the video track exactly as it is and leaves the audio track out. Nothing is decoded or recompressed, so:

• The picture quality is identical to the original.
• It finishes in seconds, even for long videos.
• The file gets a little smaller, because the audio data is gone.

MP4, MOV, M4V and MKV files are saved as MP4. WebM files with VP8, VP9 or AV1 video stay WebM, because copying those streams unchanged keeps the job lossless; if you need an MP4 that plays on iPhones and TVs, convert it with WebM to MP4 afterward. The result is named after the original with -muted added, so your source file is never overwritten. If the video has no audio track at all, the tool tells you; you can still run it to repackage the file into another format.

• Background noise: wind, traffic or chatter that ruins an otherwise good clip.
• Privacy: conversations you don't want to share along with the footage.
• Adding your own music or voice-over in an editor, starting from a clean silent track.
• Website backgrounds and autoplay: browsers generally allow autoplay only for muted videos, and a video with no audio track at all is the safest choice.
• Copyright: removing background music that would get a social post muted or blocked anyway.
• Smaller files for presentations and documentation.

If you need only part of the video, trim it and tick Remove audio in the same step. To shrink the file a lot, the video compressor also has a remove-audio option. And if you want the opposite, to keep the sound and drop the picture, use an audio extractor or video-to-MP3 converter instead.

Muting in a video player or a phone's gallery app usually only hides the sound during playback; the audio is still in the file when you send it. This tool removes it from the file itself.

After muting, the result card plays the new file right on the page, so you can confirm there's no sound before you download it. The download button shows the new file size next to the original's. If you later need the sound again, keep your original file: removing an audio track can't be undone in the muted copy.

Muting works on any length of video and on several files in a row: click Another video to start over with the next one.

Your video is never uploaded. It's read, processed and saved on your own device, which is faster than sending a large file to a server and keeps the content private. Because no encoding is needed, this tool works even in browsers without full WebCodecs support, as long as they can read the file. Very large files depend on your device's memory, and the tool warns you if a file is large.
