🔒 Your files never leave your device

How to use it

Drop your file into the box or click to choose it.
Pick the aspect ratio, then the fill mode — "blurred background" keeps the whole video and looks pro.
Press "Start" and download the result. Done!

What size is TikTok and Reels?

9:16 vertical at 1080×1920 or 720×1280.

Crop vs blurred background?

Crop fills the screen but cuts the edges; blur keeps the whole video and fills the gap with a blurred copy.

Is it free?

Yes — completely free, no sign-up and no watermark.

Are my files uploaded to a server?
