Audio Remover

Strip the audio track from any video instantly — no sign-up, no uploads, nothing to install. FFmpeg runs entirely in your browser using WebAssembly, so your video never leaves your device. Processing uses stream copy mode, meaning there is zero re-encoding and no quality loss.

How It Works

1

Choose your video

Drop any MP4, WebM, MOV, AVI, or MKV file. It loads into browser memory only — nothing is transmitted to a server.

2

Load FFmpeg once

On first use, FFmpeg WebAssembly (~25 MB) downloads to your browser cache. Every subsequent use skips this step entirely.

3

Remove the audio track

FFmpeg uses stream copy mode to strip only the audio stream. No re-encoding happens — the video quality is pixel-perfect and the process takes seconds.

4

Preview & download

Play the silent video in the built-in preview, then download your muted file. No server round-trip ever occurs.

Why remove audio in the browser?

  • Your video never leaves your device — FFmpeg WebAssembly runs in a sandboxed browser tab. No bytes are sent over the network.
  • Zero quality loss — stream copy mode copies the video track byte-for-byte. There is no transcoding, no generation loss, and no compression artefacts.
  • Instant results — because the video stream is not re-encoded, even a 500 MB file typically processes in a few seconds.
  • No size limits imposed by upload bandwidth — since nothing is uploaded, the only constraint is your device's available memory. The tool handles files up to 500 MB.
  • Works on any platform — phone, tablet, or desktop; Mac, Windows, or Linux. No app or plugin to install.
  • Completely free — no account, no watermarks, no hidden fees.

When would you need to mute a video?

  • Background music replacement — strip the original audio before adding a royalty-free track in your video editor.
  • Removing sensitive audio — eliminate confidential conversations, ambient noise, or unintended recordings before sharing a clip.
  • Social media posts — many platforms auto-play videos silently; removing audio avoids accidental sound playback.
  • Presentations and screencasts — export a silent version to add your own narration or background music in a slide deck.
  • File size reduction — the audio stream typically adds a few megabytes; removing it produces a slightly smaller file at the same video quality.

Frequently Asked Questions

Is my video uploaded to a server?

No. All processing happens locally in your browser using FFmpeg WebAssembly. Your video bytes are never transmitted to any server — everything runs on your device.

Will removing audio reduce the video quality?

No. The tool uses FFmpeg's stream copy mode (-c:v copy), which copies the video stream byte-for-byte without re-encoding. Only the audio track is stripped — the video quality is identical to the original.

Why does it need to download ~25 MB before processing?

The tool uses FFmpeg compiled to WebAssembly. This one-time ~25 MB download is cached by your browser, so every use after the first is instant without re-downloading.

What video formats are supported?

The tool supports any format FFmpeg can demux: MP4, WebM, MOV, AVI, MKV, MPEG, OGG, and more. The output keeps the same container format as the input file.

Is this tool really free?

Yes, completely free. No account required, no watermarks, and no hidden fees. The tool uses open-source FFmpeg compiled to WebAssembly.

Privacy & Security

All processing happens locally in your browser using FFmpeg WebAssembly. Your video is never uploaded to any server. The FFmpeg WASM binary (~25 MB) is fetched once from a CDN and cached in your browser for instant future use.
