Quick reference
- ● Lower radius = subtle softening effect.
- ● Higher radius = stronger, more abstract blur.
- ● Preview updates as you drag the slider.
- ● Everything runs locally — your image never leaves your device.
Why it matters
Blur is essential for privacy (hiding faces or text), depth-of-field effects, and creating abstract backgrounds. A subtle blur can also reduce noise in low-quality photos and make overlaid text more readable.
Frequently asked questions
How does image blur work?
Blur works by averaging the color values of neighboring pixels. A larger radius means each pixel is averaged with more neighbors, producing a softer, more diffused result. Gaussian blur uses a bell-curve weight distribution for smooth, natural-looking blur.
Can I blur just part of an image?
This tool applies blur to the entire image. To blur only a portion, you would need to use a photo editor with selection or mask features. You can crop a specific area first using our crop tool, then blur it.
What blur radius should I use?
For subtle softening, use 1-3px. For background blur or privacy masking, use 8-15px. For a fully abstract effect, use 15-20px. The best radius depends on your image resolution and desired effect.
