What is the Sigma value?

Sigma represents the standard deviation of the Gaussian distribution. A higher value results in a more intense, widespread blur.

How does Kernel Size affect the image?

The kernel size determines the area of pixels used to calculate the blur. Larger kernels create a heavier, more noticeable blur effect.

Can I apply the blur multiple times?

Yes, you can use the 'Iterations' setting to apply the Gaussian blur effect multiple times in a single pass for a stronger result.

What file formats are supported?

The tool supports common image formats including JPEG, PNG, WebP, GIF, BMP, and TIFF.

What do the output modes do?

Output modes like 'Enhanced', 'Vintage', or 'Dramatic' apply additional color and contrast adjustments to the blurred image to achieve specific artistic looks.
