Frequently Asked Questions
What is video compression?
Video compression reduces the file size of a video while trying to preserve visual quality. It works by encoding data more efficiently.
Are my videos uploaded?
No. This tool processes videos directly in your browser. Your videos are never sent to a server.
Which video formats are supported?
The tool supports common browser video formats such as MP4, WebM and AVI.
Does compression reduce video quality?
The quality slider lets you balance size and quality: higher values keep more detail, lower values shrink the file more.
Is it really free and unlimited?
Yes, the tool is completely free and you can compress as many videos as you want, with no limits.
Does it work on mobile too?
Yes, it works on any modern device, including smartphones, tablets and desktop computers.
Does the compressed video keep the original format?
Yes. A WebAssembly video engine processes the file directly in your browser, re-encoding the content while keeping the same container: an MP4 stays MP4, a WebM stays WebM, and so on. Your files never leave your device.
