Mute Video
Remove audio tracks from any video file without re-encoding. Maintain pristine video quality with instant in-browser stream copy and zero server uploads.
MP4, WebM, MOV, MKV, AVI, FLV, 3GP · up to 1 GB
Tips
- The browser downloads a 30 MB WebAssembly media engine on your first visit, which caches locally to work offline later.
- The video stream is copied directly without re-encoding, preserving full image resolution and finishing in seconds.
- If you need to keep the audio as an independent soundtrack, extract it with a separate audio extraction tool first.
How to use it
- 1 Select or drop your video file into the work area.
- 2 Start the process to strip the audio tracks using stream copy.
- 3 Save the muted video file directly to your device.
What you should know
Muting a video is essential when preparing background loop videos for web banners, eliminating ambient background noise, or removing copyrighted background music before publishing. Video containers such as MP4, WebM, and MKV multiplex separate video and audio streams together. Web browsers often block autoplaying media unless the audio stream is silenced or removed entirely. Stripping audio reduces overall file size by the bitrate of the soundtrack—typically 128 kbps to 320 kbps for standard AAC or Opus tracks—while ensuring compatibility across desktop and mobile playback environments without playback conflicts.
This tool performs a direct stream demuxing process that drops all audio tracks while copying the video stream bit-for-bit. Because the underlying video codec data—whether H.264, HEVC, VP9, or AV1—is preserved without transcoding, the operation introduces zero generational compression loss and completes almost instantaneously. The tool strips all embedded audio channels, including multi-track commentary or surround sound, leaving only the visual stream inside the output container. Once the audio track is deleted, it cannot be reconstructed from the muted file, so keep your source video if you need the audio later.
Frequently asked questions
Does removing the audio decrease the video quality?
No. The video stream is copied directly without re-encoding, so resolution, bitrate, color data, and frame rate remain 100% identical to the source.
Will muting a video reduce its file size?
Yes, the output file will be smaller by the exact size of the removed audio stream, which usually ranges from 1 MB to 3 MB per minute of video.
Are multiple audio tracks or alternate languages also removed?
Yes, the tool strips all audio streams multiplexed inside the container, producing a completely silent video track.
