Remove Audio from Video

Remove audio from a video without re-encoding it

This tool lets you remove audio from video files in seconds. Drop in an MP4, MOV, WebM or MKV and download a silent copy — or, for a file with several audio tracks, tick the ones you want to keep and leave out the rest, such as a second language or a director’s commentary.

Because only the sound is removed, the picture is never decoded or compressed again. The video stream is copied packet by packet into a new file — a remux — so the result looks exactly like the original, keeps its resolution and frame rate, and is ready almost instantly, even for long recordings. Everything happens in your browser; the file is not uploaded.

How to remove audio from a video

1. Drop a video on the upload area or click it to choose one. The file’s format, length and audio tracks are listed.
2. Under Tracks to keep, the video is ticked and every audio track is unticked. To keep some audio, tick those tracks or use Keep all audio.
3. Choose the Output format. The original container is selected by default; only formats that can hold your tracks without re-encoding are offered.
4. Press Remove audio (or Save selected tracks). The new file downloads automatically and appears in the result player.

Remove Audio from Video features

Why remove the sound from a video?

• Background noise or private conversations recorded by a phone or dashcam that you don’t want to share.
• Copyrighted music that would get a clip muted or blocked on social media — remove it, then add your own track with Add Audio to Video.
• Silent loops for website backgrounds, presentations and digital signage, where browsers only autoplay muted video anyway.
• Stock footage and B-roll that will be edited under a voice-over.
• Multi-language files where you only need one language and want a smaller file.

What is a remux, and why does it matter?

A video file is a container holding separate streams: usually one video track and one or more audio tracks, each already compressed. Most online tools that “remove audio” decode and re-encode the entire video, which takes as long as a full conversion and loses a little quality each time. Removing a track doesn’t require that: the remaining packets can be written into a fresh container untouched.

This page does the remux with Mediabunny, an open-source media library (MPL-2.0) that runs in the browser, loaded unmodified from a CDN. Because no encoder is involved, it even works in browsers without WebCodecs video encoding. The output is usually smaller than the original by exactly the size of the removed audio — around 1 MB per minute for 128 kbps AAC.

Things to know

Subtitle, closed-caption and timecode tracks inside the file can’t be read by the browser engine, so they are left out; the page warns you when a file contains them. Save subtitles first with Extract Subtitles. The output is built in memory, so very large files (several gigabytes) need a device with plenty of RAM. If you want a smaller file overall, run the result through the Video Compressor.
