Frequently Asked Questions — Image Blur Tool
What is Gaussian blur?
Gaussian blur applies a weighted average to each pixel based on surrounding pixels, creating a smooth natural-looking blur.
Can I blur only part of an image?
Yes. Selective blur mode lets you draw a rectangle over the area to blur. Useful for obscuring faces or sensitive text.
Does blur reduce file size?
Blurred areas compress more efficiently, so a heavily blurred image will typically be smaller when saved as JPG.
