What is gaussian blur and how does it work?
Gaussian blur smooths an image by averaging each pixel with its neighbors using a bell-curve weighting. It creates a natural, soft look ideal for blurring backgrounds, faces, or sensitive information in screenshots.
Can I blur background online with this tool?
Yes, you can blur background online by uploading your photo and adjusting the radius slider. The gaussian blur effect isolates the subject by softening the background for a professional depth-of-field look.

Absolutely. Our blur picture browser tool processes everything locally using the Canvas API. Your images never leave your device — no upload, no server, no privacy risk.
