Bulk Audio Remover Online — Free Browser-Based Tool

What this tool does

Bulk Audio Remover strips the audio track from your video files using a WebAssembly build of FFmpeg that runs entirely inside your browser tab. Because the processing happens locally, your video files never leave your device — there is no server upload and no remote storage. The output video keeps the exact same resolution, frame rate, codec and bitrate as your source, because the video stream is copied byte-for-byte and only the audio stream is dropped.

How to use it

1. Open the homepage and drag one or more video files into the drop zone (or click to pick from your device).
2. Click Process All. Each file is muted in a few seconds.
3. Download individual silent files, or grab the whole batch as a single ZIP.

• No quality loss — stream-copy muting preserves the original video data exactly.

Frequently asked questions

How does the bulk audio remover work?

The tool uses FFmpeg.wasm, a WebAssembly version of the industry-standard FFmpeg, to process videos directly in your browser. Drag and drop your video files and the audio track is stripped without re-encoding the video, preserving 100% of the original quality.

Is this online audio remover really free?

Yes, completely free. No hidden charges, no watermarks, no file size limits, no account required.

Are my videos uploaded to a server?

No. All processing happens locally in your browser. Your video files never leave your device.

What video formats are supported?

MP4, MOV, WebM, and MKV. Output is saved as MP4 or WebM.

Can I remove audio from multiple videos at once?

Yes — drag and drop multiple files and process them all in bulk. You can download every processed file as a single ZIP archive.

Why is processing slow for very large files?

Processing runs on your device's CPU and RAM. Files over ~1 GB take longer; closing other tabs helps.
