How to Blur an Image Online
Our Image Blur tool applies a professional Gaussian blur effect to your images. Blurring is useful for creating background effects, protecting private information, focusing attention on specific areas, creating dreamy or soft photo effects, and preparing images for social media graphics where a blurred background enhances the design.
- Upload the image you want to blur.
- Adjust the blur intensity slider — higher sigma values produce stronger blur.
- Click "Blur Image" and download the result.
Common Uses for Image Blurring
Image blurring is widely used in photography for creating bokeh-style backgrounds, in privacy protection for blurring faces or license plates, in graphic design for creating depth of field effects, and in web design for creating soft, semi-transparent overlays. The Gaussian blur algorithm we use produces smooth, natural-looking results that simulate real camera optical blur.
Frequently Asked Questions
How much blur can I apply?
You can control the blur intensity from a subtle 1 to a heavy 50 using the sigma slider.
What is the blur sigma value?
Sigma controls the radius of the Gaussian blur. Higher values produce more blur.
Can I blur just part of the image?
Currently, the tool applies blur to the entire image. For selective blurring, use our other editing tools.
