Frequently Asked Questions

What is gaussian blur?
Apply smooth Gaussian blur — soften backgrounds and reduce noise. Adjust the radius slider to control the intensity of the blur effect.
Can I blur just part of the image?
This tool applies blur to the entire image. For selective blur (background, face, etc.), use our specialized blur tools like Blur Background or Blur Face.
What blur radius should I use?
Start with 10px. Lower values (1-5) create subtle softness. Higher values (20-50) create strong blur. The right setting depends on your image and purpose.
