Strip sound from any MP4 file directly in your browser. No upload, no signup, no quality loss — and you can mute multiple MP4s in bulk.
Removing audio from an MP4 video used to mean installing desktop software like Premiere Pro or VLC. Today you can do it entirely in your browser in three steps:
Most online MP4 audio removers re-encode your video, which means decoding every frame and compressing it again. The result: a noticeably softer image, color shifts, and a much larger file.
Our tool uses FFmpeg.wasm with the -c:v copy -an flag. This copies the original video stream byte-for-byte and simply omits the audio track. Your MP4 keeps its original bitrate, resolution, frame rate, and codec. It is mathematically identical to the source — just silent.
If you record screen captures, dashcam clips, drone footage, or social-media B-roll, you probably have dozens of MP4 files that all need the same treatment. Drag them all in, hit process, and download the whole batch as a ZIP. No queueing, no per-file uploads, no waiting for a server.
Because everything runs as WebAssembly inside your browser tab, your video files are never uploaded to any server. This matters for sensitive footage — internal screen recordings, client work under NDA, personal videos. The page works fully offline once it has loaded.
The same tool also handles MOV (iPhone), WebM, and MKV files. If you have a mix of formats, just drop them all in — each file is processed natively without forcing a conversion.
No. We use stream copying, which means the video data is never decoded or re-encoded. The output MP4 is bit-identical to your source video — just without the audio track.
There is no hard limit, but processing happens in your browser using available RAM. Files under 2 GB work smoothly on most modern devices. Very large files may require closing other tabs.
Yes. Drop or select as many MP4 files as you need. They are queued and processed one after another, then bundled into a single ZIP for download.
No installation, no plugins, no account. The tool runs entirely in your browser using WebAssembly.
Yes. The output is a standard MP4 container with the original H.264 (or HEVC) video stream — fully compatible with iOS, Android, Windows, macOS, and every social platform.
