Why creators use it

Blurred background

Keeps your whole picture visible and fills the rest with a soft, darkened blur — the look you see on popular Shorts.

Every social size

9:16 for YouTube Shorts, Instagram Reels and TikTok, 1:1 square, 4:5 for feeds, or back to 16:9 for YouTube.

Private and fast

Runs in your browser with its built-in video engine. Your video is never uploaded.

Your video stays with you

The work is done by your browser’s own video engine on your phone or computer. Your files are never sent to a server.

Frequently asked questions

What size is a YouTube Short or Instagram Reel?

Both use a vertical 9:16 frame, such as 1080×1920. Choose 9:16 in the tool and your video is resized to fit.

Will my video be cut off?

Not with “Blurred background” or “Black bars” — the whole picture stays visible. “Crop to fill” zooms in to fill the screen, so the edges are trimmed.
