Mobile processing guidance
On mobile, start with a short MP4/WebM under 50MB before trying larger clips.
Max 200MB in this browser version.
FFmpeg uses this tab's CPU and memory after you start processing.
If processing stalls, stop and retry with a shorter clip, lower resolution, or higher CRF.
File limit
Use files under 200MB. Smaller clips are more reliable on mobile.
Processing time
FFmpeg loads after you click the action button, then uses local CPU and memory.
Common failures
Unsupported codecs, low memory, very large files, or long clips can fail.
H.264 video with AAC audio for broad compatibility.
Keep the source dimensions.
This tool exports a silent video by default.

FFmpeg is designed to run in the browser only after you start processing, and the large WebAssembly engine is served from this site.
A video mute tool removes the audio track from a video and exports a silent copy.
This browser-side version is best for short clips under 200MB.
Short local videos
Smaller clips finish faster and use less memory on mobile devices.
Clear destination format
Choose MP4 for broad compatibility or WebM for browser-native publishing.
Example
Upload a short MP4 product clip, keep MP4 output, remove audio, and download a silent preview for a landing page.
Assumption
The source video is under 200MB and the browser has enough memory to process it.
Limitation
This tool does not edit captions, subtitles, or multiple audio-track choices. It creates a silent video output.
Expecting lossless stream copy
This tool re-encodes the silent output. Use quality and resolution settings intentionally.
Forgetting captions
Removing audio does not create captions or subtitles. Add captions separately if the content needs context.
Handling source files on shared devices
Avoid using sensitive videos on shared computers, and clean up downloaded outputs when the task is finished.
Silent autoplay
Prepare silent clips for web pages or social previews.
Privacy cleanup
Remove background audio before sharing a screen recording.
Product demos
Create quiet looping videos for documentation or landing pages.
Smaller exports
Remove audio when sound is not needed.
