Mute video
Take the sound out of a video, for example before posting it or when the background noise is not wanted. The picture is kept exactly as it was. Everything happens on your own device, using the video engine built into your browser, so your video is never uploaded.
How to use it
- Choose your videos, or drag them onto the box.
- The sound is removed on your device; the picture is not changed.
- Download each video, or all of them together as a ZIP file.
No loss of picture quality
Only the sound is taken out. The video itself is moved across unchanged, so it keeps its full quality and the job takes seconds. To keep the sound separately, use MP4 to MP3.
Limits
Videos are converted in the browser's memory, so very large files are refused before anything starts; the page shows the largest size tested on your kind of device. Long videos take a while, and the page must stay open and on screen while it works, particularly on a phone.
The page reads what is inside each file before it starts. Dolby Digital (AC-3) sound, which many camcorders use, is read by FilePresto's own converter, on your device. A few formats cannot be converted yet: WMV videos, and Dolby Digital Plus (E-AC-3) and DTS sound. If a file has sound that cannot be read, the page stops and says so, rather than making a silent video; you can then choose to convert the video without its sound.
Questions
Are my files uploaded?
No. The work happens inside your web browser, on your own device. Before your file is opened, this page locks itself: from then on your browser refuses to let it fetch, upload or send anything at all. You can check: once the page has loaded, switch off your internet connection and it will still work. How the lock works.
