How it works
- Drop your video file. MP4, MOV, M4V, WEBM, MKV or AVI up to 2 GB — it is read locally, nothing is uploaded.
- Remove or replace the sound. The video stream is copied as-is and the audio track is simply left out — or swapped for your own audio file, which is the only thing encoded. No video re-encoding, so it takes seconds.
- Preview and download. Check the result right in the page, then save it — same container, same image quality.
Features
- Zero quality loss. The image is never decoded or re-encoded — the video stream is copied bit for bit, only the audio track is dropped.
- Seconds, not minutes. Because nothing is re-encoded, muting a video is a remux — even a long 4K clip is done almost instantly.
- Same container in, same container out. MP4 stays MP4, WEBM stays WEBM, MKV stays MKV — plus the faststart flag on MP4/MOV so playback starts instantly on the web.
- Everything else stays. Subtitles, chapters, timecode, rotation, HDR and color tags and camera metadata are kept — and if the video has several audio tracks, you can remove just one.
- Replace the sound with your own track. Drop a WAV, MP3, FLAC, AIFF or M4A file to put your master on a Canvas, a teaser or a clip: the image is still copied untouched, only the new audio is encoded (AAC, 256 kbit/s or the bitrate of your AAC file). Choose whether the audio is cut at the end of the image, looped to fill it, or kept at full length, and shift its start to the millisecond.
- Up to 2 GB, 100% local. Your video never leaves your computer — everything runs in your browser with ffmpeg.wasm.
FAQ
Is this video muter free?
Yes. Without an account you get 2 free uses per day across AudioKit's free tools; with a free account, 5 per day. A use is only counted when you launch the processing; loading the video and reading its info is free. AudioKit Premium removes the daily limit.
Is my video uploaded to a server?
No. The video is read and processed entirely in your browser with ffmpeg.wasm — even a 2 GB file never leaves your machine. The only network call is a tiny anonymous counter that tracks your daily free quota.
Does removing the audio lower the video quality?
No — that is the whole point of this tool. The video stream is copied bit for bit into a new file without the audio track: no re-encoding, zero generation loss, and the operation takes seconds even on large files. The output is often noticeably smaller too, since the audio track is gone.
Can I replace the sound with my own audio?
Yes. Choose “Replace the sound” and drop your audio file. The video is still copied bit for bit — only the new audio is encoded, in AAC at 256 kbit/s (or at the bitrate of your file if it is already AAC; Vorbis for WEBM, which does not accept AAC). If the lengths differ, you choose: cut the audio at the end of the image with a short fade-out, loop it to fill the image, or keep it at full length — the tool tells you beforehand exactly what will happen. An optional start offset delays the audio or skips its first seconds.
Why mute a video for Spotify Canvas?
Spotify Canvas loops are always played silent, and Canvas rejects files over 8 MB — dropping the audio track is a free size win that changes nothing visually. If you also need to cut your clip to the 3–8 second window, use our Cover video tool, which has a dedicated Canvas preset.
Which video formats are supported?
MP4, MOV, M4V, WEBM, MKV and AVI, up to 2 GB. The output keeps the same container as the input — an MP4 stays an MP4, a WEBM stays a WEBM — and MP4/MOV files get the faststart flag so they start playing instantly on the web.
