Is the blur reversible?

Blur is not a reliable way to permanently hide sensitive details — light-to-moderate Gaussian blur can often be partially reversed with dedicated image-processing techniques, especially at lower strengths. For genuinely redacting something like a face, license plate, or sensitive text, a solid black box or heavy pixelation is a safer choice than blur.

Does it upload my image?

No, the blur is rendered locally with the Canvas filter API.

What blur strength should I use for a background effect?

A light-to-moderate blur usually works best for backgrounds, keeping enough shape and color visible to feel intentional rather than accidental — try a few strengths using the live preview to see what looks right for your design.

Will blurring reduce my image's resolution?

No — the blur effect changes how the pixels look, but the image dimensions and resolution stay exactly the same as the original.

Can I blur just part of an image, like a face, rather than the whole thing?

This tool applies blur uniformly across the entire image. For blurring a specific region only, you'd need an editor that supports selective or masked blur.
