What is gaussian blur?

Gaussian blur is a widely-used image blur effect that applies a mathematical blur algorithm. It creates a smooth, natural-looking blur by averaging pixel colors based on a gaussian distribution, producing professional results.

Does it reduce image quality?

The blur effect itself does not reduce image quality beyond the intended blur. The original resolution and file quality are maintained. Only the sharpness is reduced by the blur filter.

What image formats are supported?

You can blur PNG, JPG, JPEG, WebP, GIF, and BMP images. The blurred image will be saved in the same format as the original. Maximum file size is 20MB.
