Soften Images with Adjustable Blur Radius

Apply blur effect to an image with adjustable strength. Control how blurry the result is—from subtle smoothing to heavy blur. Perfect for creating glow effects, smoothing details, artistic effects, privacy protection (blur faces), simulating depth of field, or creating soft backgrounds. Great for any workflow that needs a softer, less sharp image.

What it does

Image Blur applies a blur filter to an image, softening details based on blur strength/radius. Higher blur = softer, more blurred result. Lower blur = subtle smoothing. The entire image blurs uniformly. Use it for many purposes: create glow overlays, smooth skin tones, blur faces for privacy, simulate depth of field, create soft backgrounds, or add artistic blur effects.

Problem it solves

• Create blur effects – Apply softening/blur to entire image
• Glow layer creation – Blur images to create glow overlays for Image Add
• Privacy protection – Blur faces or sensitive content
• Depth of field simulation – Create shallow depth of field look
• Smooth details – Reduce noise, smooth skin, soften textures
• Artistic effects – Create soft, dreamy, blurred aesthetic
• Background softening – Blur background to soften appearance
• Effect preparation – Create blurred version for compositing with Image Add/Multiply

Input/Output

• Input: Single image (any size)
• Output: Blurred image

Configuration Options

• Kernel Size (Blur Radius): The size/radius of the Gaussian blur window.
  • Range: Typically 3 ~ 21 (3×3 to 21×21)
  • Effect: Larger kernel = softer, more blurred result
  • Performance: Larger kernels slower to process
  • Examples: 3 (3×3, subtle), 7 (7x7, medium), 13 (13×13, heavy)
• Color Multiplier (Brightness Adjustment): Multiplies the color brightness of the blur.
  • Range: Typically 1.0 to 2.0 (or higher)
  • Effect: Controls glow vs shadow intensity
  • Examples: 1.0 (normal), 1.3 (bright glow)
  • Use cases: >1.0 for glow effects
• Iteration (Blur Passes): How many times the blur is applied.
  • Range: Typically 1 to 5+ passes
  • Effect: More iterations = stronger, deeper blur
  • Performance: More iterations = slower processing
  • Examples: 1 (light), 2 (medium), 3+ (heavy)
