Can I blur just part of the image?

Not yet — currently full-image only. Selective blur is on the roadmap.

Are my images uploaded?

No. Filter applied locally via Canvas.

What's a good blur radius for backgrounds?

5-15 px for subtle, 20-30 px for strong. Above 30 px the image becomes mostly color.
