What is Gaussian Blur?

Gaussian blur is a type of image filter that reduces detail and noise by averaging out pixels around each point. It is based on a mathematical function called the Gaussian function, which creates a natural, smooth transition between sharp and blurred areas. Unlike simple blur filters, Gaussian blur produces a more realistic and visually pleasing result, often used in photography, design, and editing.

This effect is commonly applied to:

• Smooth out rough edges in images
• Create depth by blurring backgrounds
• Hide sensitive information
• Add artistic effects to photos

Gaussian blur is more than just an effect - it's a powerful tool for both professionals and casual users:

• Photographers use it to simulate depth of field.
• Designers apply it for smooth transitions in graphics.
• Social media users blur backgrounds to highlight subjects.
• Everyday users rely on it to hide private details before sharing pictures online.
