Image Blur Tool — Add Blur Effect Free — No Software Required

Add Gaussian blur to any image for privacy protection, background softening, or creative photo effects. Blurring sensitive information like faces, license plates, addresses, and personal details before sharing images is a common privacy practice. Background blur creates a depth-of-field effect that draws attention to the main subject. The blur radius control lets you choose from a subtle soft focus to heavy motion blur. Real-world uses include privacy protection in screenshots, social media images, and documents, as well as artistic photo editing.

Frequently Asked Questions

Gaussian blur is the most natural-looking blur algorithm. Each pixel becomes an average of its neighbors, weighted by a bell-curve distribution. The result looks like an out-of-focus photograph rather than a mechanical smear.

Radius 2-3 gives a subtle soft focus. Radius 5-10 creates visible blurring. Radius 15+ produces heavy blur good for hiding sensitive information.
