Understanding Gaussian Blur

Gaussian blur is a widely used image processing technique that smooths out pixel noise and reduces detail. It works by averaging the color values of each pixel with its neighbors, weighted by a Gaussian distribution. The result is a soft, out-of-focus effect that resembles looking through a frosted glass or an out-of-focus camera lens.

Blur Intensity Guide

  • Radius 1-3 (Light Blur): Subtle softening, reduces minor noise and sharpness. Perfect for slight background softening.
  • Radius 4-8 (Medium Blur): Noticeable blur, good for hiding details while maintaining shape recognition. Ideal for hiding faces or text.
  • Radius 9-15 (Heavy Blur): Strong blur, significantly distorts details. Great for artistic effects or complete anonymization.
  • Radius 16-20 (Maximum Blur): Extreme blur, shapes become unrecognizable. Perfect for abstract backgrounds or maximum privacy.

  • Input Formats: JPG, JPEG, PNG, WebP, BMP, GIF
  • Output Format: PNG (lossless, supports transparency)
  • Max File Size: 20MB per image

Tips for Best Blur Results

  • Use higher resolution images for better quality output
  • For hiding text or faces, use radius 10-15 for complete obscurity
  • For artistic background blur, use radius 3-8
  • PNG format preserves transparency and quality
  • For social media, a radius of 5-10 creates attractive soft backgrounds
  • Test different radius values to find the perfect blur level for your needs

Q1: Is this image blur tool really free?
A: Yes, completely free with no hidden charges, premium plans, or registration requirements. Use it unlimited times.

A: Our tool applies blur to the entire image. For selective blurring (only faces or specific areas), please use our AI Image Editor which offers selective editing features.

Q3: What's the difference between Gaussian blur and other blur types?
A: Gaussian blur is the industry standard that creates the most natural, smooth blur effect. It's commonly used in photography for depth-of-field effects.

Q4: Will the image quality be reduced after blurring?
A: The blur effect reduces detail intentionally, but we preserve the original resolution and color quality. Output is saved in high-quality PNG format.
