Frequently Asked Questions
Everything you need to know about using our Video Compressor tool effectively
Is this video compressor free to use?
Yes, our video compressor is completely free. You can compress as many videos as you need without any cost or watermarks.
Will I lose video quality after compression?

Are my videos safe? Do you store them on your server?
Your privacy is our priority. All video processing happens directly in your browser using WebAssembly. Your videos are never uploaded to our servers and never leave your device.
What video formats are supported?
We support most popular video formats including MP4, WebM, MOV, and AVI. The compressed output is usually in MP4 format for maximum compatibility.
Why is the compression taking a long time?
Video compression is a processor-intensive task. The time it takes depends on your computer's CPU speed and the size/length of the original video. Large 4K videos will take longer than shorter 1080p clips.
