How it works
One flow. A silent MP4 in moments.
1. Add your video
Drop an MP4, MOV, WebM, MKV, or other file your browser can open—AVI and more may work if the codec is supported. Everything stays on your device; nothing is uploaded for processing.
2. Click Remove audio
We remove every audio track. When the file can be remuxed to MP4, the video is copied without re-encoding for the same look and a quick result. If the format or codec does not allow that, the tool may re-encode the video to H.264 in MP4 so you still get a file you can play—keep the tab open for large or long videos.
3. Download your silent video
You get an MP4 with no audio. When stream copy works, the picture matches the source, and the file is often smaller without the audio data.
Key features
Stream copy when possible
Same idea as desktop tools: copy the video bitstream, drop the audio. When remuxing works, you skip a full re-encode and get a faster result.
No quality loss (with stream copy)
If the output can be remuxed from your source, the video is not re-encoded, so the picture matches the input. A transcode to MP4 is only used when remuxing is not possible.
Wide format support (input)
Use MP4, MOV, WebM, MKV, and many other common containers—if the browser and decoder support your codec, you can process it. Output is MP4 for maximum compatibility.
No upload
Demux, any needed transcode, and mux all run in your browser. You do not upload your file to strip the soundtrack here.
No watermarks on export
The file you download is yours—no branding, logos, or forced overlays from this page.
All audio tracks removed
This tool always removes every audio track in the file. To keep one language track and remove another, use desktop software with per-stream control.
Popular use cases
🎵
Replace background music
Remove the original audio, then add your own music, voice-over, or SFX in an editor. Starting from a silent clip makes the sound layer easier to handle.
©️
Remove copyrighted audio
Strip music or other audio that could hit Content ID or platform copyright checks; then add royalty-free or licensed sound before you upload to YouTube, Instagram, or TikTok.
🌐
Silent autoplay and hero videos
Autoplay rules favor muted video. A file with no audio is a clean choice for page backgrounds, hero loops, and kiosks—not only the muted attribute.
🌍
Prepare for dubbing
Remove the original dialogue so you can add a full dub in another language—typical in localization, e-learning, and marketing video workflows.
🔐
Remove sensitive audio
Screen recordings, calls, and meetings can include private speech. Remove the track before you share the picture more widely.
📦
Smaller file size
Audio is often 5–15% of a file. Removing it saves space when every megabyte counts.
🔁
Looping background videos
Silent loops work well for site backgrounds. No audio means no surprise sound when a loop autoplays.
What is a video audio remover?
A video audio remover drops the audio stream (or all of them) from a video file, giving you a silent video with the same picture when stream copy is used. It is a simple job and often a fast one, because the video can often be copied as-is.
Most videos are container files (MP4, MKV, etc.) with a video track and an audio track. The process copies the video to a new file and leaves the audio out. On a desktop, tools like FFmpeg use something like -c copy for video and -an for no audio; this page does the same job in the browser with modern media APIs—there is no FFmpeg server farm behind this tool.
That is not the same as heavy compression, where every frame is decoded and re-encoded. The goal here is to drop audio, not to change the picture—unless a remux to MP4 forces a one-time transcode on your device.
Why remove audio from a video?
Here is where creators and teams do it most often:
Copyright and platform policy
Content ID, audio matching, and takedown rules are strict. Many teams strip the audio, then add cleared music or a voice-over before posting.
Autoplay and web design
Muted or silent video fits autoplay and loop designs without extra scripting.
Localization and dubbing
The original dialogue goes away so new language tracks or narration can be mixed cleanly.
Privacy and compliance
Share the screen or slides without the conversation that was in the room.
Editor workflow
Import a silent master and add sound in the NLE for full control of levels, timing, and effects.
Technical details: how it works
Removing all audio from a file follows the same idea as this classic command-line pattern on your own machine (not on our servers here): copy the video stream, disable audio, write a new container.
Reference (FFmpeg on desktop—educational only)
ffmpeg -i input.mp4 -c:v copy -an output.mp4
- • -i: input file
- • -an: no audio in the output (all audio streams dropped)
- • -c:v copy: copy the video bitstream when the container and codec allow
In the browser, this page follows the same idea: remux when it can, and transcode the video only if a valid MP4 needs it. Time depends on your device, codec, and file size—not the same for every clip.
If your source has several language or commentary tracks, -an and this tool remove all of them. There is no per-track picker on this page.
We output MP4 for compatibility. If you have odd legacy containers, convert or remux somewhere else first, or test with a short clip.
How fast is “remove audio”?
Stream copy is much faster than a full re-encode, but a browser on a typical PC is not the same as FFmpeg on a workstation. Most everyday files finish quickly; very large or 4K files can still take longer or need more memory.
| Rough file size | Remove audio (this page, local) | Re-encode to compress (rough range) | Full re-encode or convert (rough range) |
|---|---|---|---|
| ~100 MB | Often seconds to a minute or two | Minutes | Minutes |
| ~500 MB | Varies; often a few minutes | 5–15+ min | 5–15+ min |
| ~1 GB | Varies; can be several minutes | 10–30+ min | 10–30+ min |
| ~4 GB | Varies; can run a long time | 40–120+ min | 40–120+ min |
Removing audio is still usually far faster than two-pass video compression, because it can skip touching every pixel when remuxing works.
Frequently asked questions
How long does removing audio take?▾
It depends on file size, resolution, and whether the tool can remux (stream copy) or has to re-encode. Many clips finish in seconds to a few minutes. Huge files can take longer—keep the tab open and avoid other heavy work on the same machine.
Will removing audio hurt video quality?▾
When the video is copied into the new MP4 without re-encoding, the picture is effectively unchanged. If a transcode to H.264 is required for compatibility, you may see small differences—start from a high-quality source.
What input and output formats are supported?▾
Input: common containers such as MP4, MOV, WebM, MKV, and more, when your browser can decode the codecs (AVI and others are best-effort). Output: MP4 (H.264) for the widest playback support.
Can I remove audio from only part of a video?▾
This page processes the whole file. For a range, use our Video Trimmer to export the part you need, then remove audio, or do it in an editor. You can merge pieces again with the Video Merger if that fits your workflow.
Can I save the audio to a separate file?▾
This tool only outputs a silent video. For a separate audio file, use other software or a converter that can export audio.
Does removing audio make the file smaller?▾
Usually. Audio is often 5–15% of the total; the exact amount depends on bitrate and length.
Is my video private?▾
Yes. Processing runs locally in the browser. We do not receive your file to remove the track for you.
Do I need an account?▾
No. You can use the tool without signing up.
What if there are several audio tracks (languages)?▾
All of them are removed. This page has no per-track picker. For that, use a desktop editor or a specialized tool with stream or track selection.
Why does the tool fail in some browsers?▾
Encoding and muxing depend on WebCodecs and related APIs, which are not fully available in every browser—especially some Firefox versions. Use a recent Chrome, Edge, or Safari for the most reliable results.

Why FreeVideoGenerator.io?
Removing audio should be private, free, and simple—not a reason to upload a whole project to a random cloud. This page runs in your browser, uses stream copy when it can, and does not add watermarks.
Add your file, run remove audio, download MP4. No paywall, no sign-up wall.
Practical limits
Very long videos, 4K, or rare codecs can be slow, fail, or need a re-encode. Phones have less memory. Use a current Chrome, Edge, or Safari for the best experience; WebCodecs support in Firefox is still more limited in many cases.
