Understanding Image Blur Effects
Blur effects have many practical applications: censoring sensitive information (faces, license plates, numbers), creating background bokeh effects, simulating motion, and focusing attention on specific areas. Gaussian blur is the most common type, which uses a mathematical function to smooth pixel values by averaging surrounding pixels.
The blur radius determines intensity: a radius of 1-3px creates a subtle softening effect for skin retouching, while 10-20px creates strong blurring suitable for censoring or dramatic effects. Larger radii produce smoother results but require more processing time.
- Use a small blur radius (2-5px) for subtle skin softening in portraits
- Censor sensitive information with 15-20px blur radius for complete privacy
- For background blur effect (bokeh simulation), blur radius 8-12px works well
- Apply blur before sharpening for the best overall result
- Gaussian blur effect
- Adjustable radius (1-20px)
- Hide sensitive information
- Create depth-of-field effects

FAQ
How can I blur a face in a photo?
Upload your photo, then use the blur slider. Start with a radius of 5-10px for face blurring. Higher values create stronger blur effects.
Is the blur effect free?
Yes, all image tools including blur are completely free with no limits.
What blur styles are available?
Gaussian blur, motion blur, radial blur, and zoom blur effects are available.
Can I blur only part of an image?
Yes, use the brush tool to selectively blur specific areas of your image.
