Is my video uploaded to a server?

No. The conversion runs entirely in your browser, so your video never leaves your device.

What's the difference between blurred background and center crop?

Blurred background keeps the whole original video visible and fills the empty space above and below with a blurred copy. Center crop zooms in and trims the sides so the video fills the whole vertical frame.

Why is conversion slow on long videos?

Processing happens on your own device, so speed depends on your computer. Shorter clips finish much faster, and a 150MB file size limit keeps things manageable.

Conversion runs entirely in your browser, so your video is never uploaded. The first run downloads the video engine (about 30MB), and longer videos take more time on slower devices.
