Remove audio from video
Strip the soundtrack from a clip in one click — the video stream is untouched, so there's zero quality loss.

Removing audio from a video deletes the file's audio track while leaving the video stream exactly as it was. Unlike editors that re-render the whole clip, this tool copies the picture data untouched and simply writes out a new file with no sound — a container remux rather than a re-encode. That's why there's no change to resolution, bitrate, or frame rate, and why you get a genuinely silent MP4 instead of one with the volume just pulled down to zero.
For Suno creators, muting a clip is usually the first step before pairing footage with your own track. Stock B-roll, screen recordings, and even Suno's own exported preview videos ship with audio you don't want competing with your song, so stripping it out gives you a clean silent base to drop into CapCut, Premiere, or a platform's built-in editor. It's also the fastest way to delete sound from a video before uploading, so the original audio can't trigger a Content ID or copyright match.
How it works
- 1
Drop the video.
- 2
Click remove audio.
- 3
Download the silent video.
When to use it
- Muting stock B-roll in the browser before importing it into CapCut, so your Suno track becomes the only audio in a lyric video.
- Stripping the built-in preview audio from a Suno-exported MP4 so you can remux it cleanly against a lossless WAV master.
- Silencing a gameplay or screen recording for a YouTube music background, so the original app audio can't clash with your track or trigger a Content ID match.
FAQ
Why mute instead of just lowering volume?
A removed track can't leak — useful before adding new music, or when background audio can't be published (copyright, privacy).
Can I add new audio after?
Yes — pair this with the replace audio tool, or do it in one step there.
Does removing the audio reduce the file size?
A little. Dropping the audio track removes its bitrate from the file, so a clip shrinks by roughly the size of that stream — often a few megabytes for a standard AAC track. The video data stays byte-for-byte identical, so the savings come entirely from the removed sound.
Which video formats can I mute?
Common containers like MP4, MOV, WebM, and MKV all carry a separate audio track that can be dropped without touching the picture, and the tool writes the muted copy back in the same container it read. Everything runs locally in your browser, so the file is read straight from your device — nothing is uploaded.
How long does it take to strip audio from a long video?
Short clips finish in seconds. Because nothing is re-encoded, muting is far faster than a full transcode — but the tool still has to copy every packet of the video stream, so the time scales with the file's size. A long, high-bitrate clip takes proportionally longer, and very large files are also limited by how much your browser can hold in memory.
