Frequently asked questions
What is Gaussian blur?
A common image blur that averages neighboring pixels using a bell curve (Gaussian function). Produces smooth, natural-looking softening — the same blur Photoshop uses.
What blur radius should I use?
1-5px for subtle softness. 8-15px for backgrounds and blur-behind effects. 20-40px for heavy privacy blur (like hiding faces or license plates).
Can this be reversed?
No. Blur is destructive — the original detail is lost. Keep an original copy if you might need it later.
Is my image uploaded?
No. All blurring runs in your browser using canvas filters. Your image never leaves your device.
