Can I blur part of an image?

ImgBolt applies a uniform Gaussian blur across the entire image. For selective blurring, use a photo editor like Photoshop or GIMP.

Is the blur reversible?

No. Blurring permanently removes detail. Always keep your original file before applying blur.

What is gaussian blur?

Gaussian blur is a smoothing filter that reduces image detail and noise by averaging pixel values using a bell-shaped (Gaussian) distribution. It creates a natural, smooth blur effect.

How do I control the blur intensity?

Use the blur radius slider to control intensity. A higher value creates a stronger blur effect. Values between 1-5 create subtle softening, while 10+ creates a strong blur.

Can I blur just part of an image?

This tool applies blur to the entire image. For selective blur, you can crop the area you want blurred, apply the blur, and composite it back in an image editor.
