Question 1

What does the blur radius control?

Accepted Answer

The blur radius determines how far the blur extends from each pixel. A radius of 1-3 creates a subtle softening effect. Higher values (10-20) produce a strong, frosted-glass-like blur.

Question 2

Can I use blur to hide sensitive information?

Accepted Answer

A high blur radius (15-20) can effectively obscure text, faces, and other details. However, for maximum security, consider using a solid-color overlay instead, as extreme image processing could theoretically recover blurred content.

Question 3

Does blurring reduce file size?

Accepted Answer

Often yes. Blurred images have less detail, which means they compress more efficiently — especially in JPEG and WebP formats. The reduction depends on the blur radius and image content.
