Frequently Asked Questions
What is Gaussian blur?
Gaussian blur uses a weighted average of nearby pixels to create a smooth, natural-looking blur effect.
What is blur radius?
Radius determines how many surrounding pixels affect each pixel. Higher values create stronger blur.
When should I blur images?
Blur works well for backgrounds, soft-focus effects, and reducing noise. Do not rely on it to hide faces or text you want kept private: blur can be reversed. To redact something, cover it with a solid fill instead.
