Prompt

Apply Gaussian Blur evenly across the photograph, softening edges in every direction with smooth, rounded transitions. Blend fine textures and grain into continuous color gradients, gently diffuse highlights, and reduce small details without directional streaks, doubled contours, or artificial surface texture. Preserve the original subject and composition.

Paste it into LetzAI with your own image to apply the effect ↗

Identify

Edges blur without a preferred direction.

Principle

A Gaussian convolution1 averages neighboring values with decreasing distance.

Try it out

Compare Sigma2 2 and 12.

Classification

Calculated image processing result.

Seattle - George Center for Community sign with Gaussian blur
02 Seattle - George Center for Community sign with Gaussian blurA community sign in Seattle contains a blurred central tree logo. The Gaussian convolution localized to the emblem obscures the fine details of the branches without affecting the surrounding sharp text.Joe Mabel · CC BY-SA 3.0 · Wikimedia Commons
Halftone, Gaussian Blur
03 Halftone, Gaussian BlurTwo grayscale close-ups of an eye compare a halftone pattern with a processed version. The Gaussian blur removes the high-frequency dots from the original image to create a smoother tonal transition.AnonymousUnknown author Alex:D · Public domain · Wikimedia Commons
Palatul Telefoanelor from Hotel Capitol 2002-major Gaussian blur for copyright reasons
04 Palatul Telefoanelor from Hotel Capitol 2002-major Gaussian blur for copyright reasonsA tall skyscraper in Bucharest appears with a heavy blur applied for copyright masking. The effect spreads the building's pixels evenly, making architectural features unrecognizable against the sharp cityscape.Joe Mabel · CC BY-SA 3.0 · Wikimedia Commons

05 Hotel Continental - Calea Victoriei-major Gaussian blur for copyright reasonsA wide shot of Calea Victoriei shows a white building intentionally blurred. This application demonstrates how a high-sigma Gaussian filter can isolate and obscure large-scale structures within a high-resolution urban photograph.Mihai Petre · CC BY-SA 3.0 ro · Wikimedia Commons
