Video Mute
Remove audio from video online free. Mute video without re-encoding using FFmpeg WASM. 100% browser-based, no upload, fast and lossless.
How does the video muter work?
Our tool removes the audio track from your video using FFmpeg WASM. In fast mode, it uses stream copy (-c:v copy -an) which simply drops the audio without re-encoding the video, resulting in zero quality loss and near-instant processing. For format conversion, it re-encodes the video with the chosen codec.
Is my video uploaded to a server?
No. All video processing happens locally in your browser using FFmpeg WASM technology. Your videos never leave your device, ensuring complete privacy and security.
What video formats are supported?
You can upload MP4, WebM, MOV, AVI, MKV and other common video formats. The muted video can be exported in the original format (fast, lossless) or converted to MP4 or WebM.
What is the difference between fast mode and re-encode mode?
Fast mode (Original format) copies the video stream directly and only removes the audio track, so there is no quality loss and processing is extremely fast. Re-encode mode (MP4/WebM) re-encodes the video, which allows format conversion but takes longer and may slightly reduce quality depending on the CRF setting.
Is this tool completely free?
Yes, this video muter is 100% free to use with no limitations. There are no watermarks added, no time limits, and no registration required.
What is FFmpeg WASM?
FFmpeg WASM is a WebAssembly port of FFmpeg, the popular multimedia framework. It runs directly in your browser, enabling powerful video processing without server uploads.
How long does it take to mute a video?
In fast mode (same format), muting is nearly instantaneous since the video is not re-encoded — only the audio track is removed. In re-encode mode, processing time depends on video size, resolution, and your device performance.
Will muting reduce the video quality?
No. In fast mode, the video stream is copied bit-for-bit without any re-encoding, so there is absolutely zero quality loss. The output video looks identical to the original, just without sound.
Does the tool work on mobile devices?
Yes, the tool works on modern mobile browsers that support WebAssembly. Fast mode is especially suitable for mobile devices since it requires minimal processing power.
Can I mute a video that already has no audio?
Yes, the tool will still process the video without issues. If the video already has no audio track, the output will be identical to the input.
What does the CRF quality setting do?
CRF (Constant Rate Factor) controls the video quality when re-encoding. Lower values mean higher quality (range 0-51, default 28). This setting only applies when converting to MP4 or WebM format, not in fast copy mode.
Is there a file size limit?
While there is no hard limit, very large files (over 1GB) may cause browser memory issues. We recommend processing videos under 500MB for optimal performance. Fast mode handles larger files better than re-encode mode.
How to Use Video Mute
Remove the audio track from any video right in your browser. Processing runs locally with FFmpeg WASM, so your file is never uploaded.
- Open a video by dropping the file onto the page or via the file picker.
- Keep the default "Original (Fast, Lossless)" option to strip audio without re-encoding the video stream.
- Choose MP4 or WebM in the format options if you also need to change the container.
- Start the muting and wait a few seconds — lossless mode usually finishes faster than playback.
- Save the muted video to your device.
If the picture must stay bit-identical, never switch away from "Original (Fast, Lossless)"; re-encoding only degrades quality.
