Remove audio from a video or adjust its volume, processed entirely in your browser, files never uploaded.
Your video is processed locally with FFmpeg running in your browser. Nothing is uploaded; the file never leaves your device. First use downloads the ~31 MB engine once. Files up to 200 MB.
50% = half volume, 200% = double volume. Large boosts may cause clipping.

There are two common reasons to touch a video's audio track: a background noise or music track you need gone before adding your own narration, and a clip that is simply too quiet or too loud. This tool handles both (remove the audio track entirely, or scale it up and down by exact percentages) without re-encoding the video itself, so picture quality stays identical and processing is fast.
Muting uses stream copy: the video track is transferred bit-for-bit and the audio track is dropped, which takes seconds even for long files. Volume adjustment re-encodes only the audio. Everything runs in your browser via a WebAssembly build of FFmpeg; the file never touches a server, which matters for private or unpublished footage.
Related jobs: extracting the audio as an MP3 file instead of deleting it (Audio Extractor), trimming the muted clip (Video Trimmer), or converting it to another format (Video Converter).
No. Removing the audio track uses stream copy: the video track is transferred bit-for-bit, so quality is identical to the original and processing takes seconds. Volume adjustment re-encodes only the audio track.
No, once the audio track is removed and you download the muted file, the audio in that copy is gone. Keep your original file, or use the Audio Extractor first to save the sound as MP3 before muting.
Digital audio clips when amplified beyond its maximum level. Boosting quiet recordings past roughly 200% often causes crackling. For heavily quiet sources, consider normalizing in a dedicated audio editor.
Files up to 200 MB are supported. Because muting copies rather than re-encodes the video, even long files near the cap finish quickly; memory is the only practical limit.
Anything FFmpeg reads: MP4, WebM, MOV, MKV, AVI, M4V, and more. The output keeps the source container and codecs, so the muted file plays wherever the original did.
