Understanding Compression
Video compression isn't magic; it's math. Raw video contains huge amounts of redundant color data.

- 2Inter-frame PredictionInstead of saving every pixel, we only save what changes between frames.

Common Questions
Will I lose quality?
Barely noticeable. We use advanced optimization that discards redundant data your eye struggles to see locally.
Why is it so fast?
Because we don't upload your file! Cloud converters take 5 mins to upload, 2 mins to convert, 5 mins to download. We just convert.
Can I compress 4K videos?
Yes, but it requires a powerful device (laptop/PC recommended). Phones might struggle with large 4K files.
Is it really free?
Yes. Unlimited use. We are supported by the ads on this page.
