How to Blur Images Online — Gaussian Blur and More

Why Blur an Image?

  • Protect privacy — blur faces, license plates, addresses
  • Create a depth-of-field effect (bokeh)
  • Blur a background to focus attention on the foreground
  • Censor sensitive information before sharing
  • Create a dreamy or artistic effect

Types of Blur

  • Gaussian blur: Soft, natural-looking blur. Most common type.
  • Motion blur: Simulates movement. Streak in one direction.
  • Radial blur: Circular blur from a center point. Speed/spin effect.
  • Box blur: Simple averaging blur. Blockier than Gaussian.

How to Blur an Image Online

  1. Open Image Blur tool.
  2. Upload your image.
  3. Choose blur type and radius (higher radius = stronger blur).
  4. For selective blur, draw a selection around the area to blur.
  5. Apply and download.

Blur Radius Guide

  • 1-3px — subtle softening
  • 5-10px — visible but artistic blur
  • 15-30px — strong blur, hides details
  • 50px+ — complete obscuring, unreadable faces/text
