Add blur effects to your images with 10 different blur types and adjustable intensity.
Size of the blur matrix. Larger values create a stronger blur effect.
Fine-tunes the Gaussian distribution. Lower values create sharper falloff.

Discover the many practical applications of blur effects
Create professional depth of field effects with Lens Blur, simulate motion with Motion Blur, or add a dreamy atmosphere with Gaussian Blur.
Blur sensitive information, faces, or personal details in images before sharing them online to protect privacy.
Create abstract art, dreamy landscapes, or stylized portraits using various blur techniques to evoke emotion and atmosphere.
Blur backgrounds to make foreground subjects stand out, create professional-looking product photos, or improve text readability on image overlays.
Use Median Blur or Bilateral Filter to reduce noise in photos taken in low light conditions while preserving important details and edges.
Create a tilt-shift miniature effect that makes real-world scenes look like tiny models or dioramas using the Tilt-Shift blur.
Learn about different blur types and when to use them
The most common and versatile blur type. It creates a smooth, natural-looking blur by applying a weighted average with pixels closer to the center having more influence. Gaussian blur is perfect for general softening, creating dreamy effects, or reducing noise.
Also known as Average blur, Box blur averages all pixels within a defined square area equally. Simpler and faster than Gaussian but can create more visible edges. Adjust the blur amount to control the effect strength.
Simulates movement by blurring in a specific direction. Used to add a sense of speed or movement to static images. Adjust the angle and length to control the direction and intensity.
Mimics the out-of-focus areas produced by camera lenses. Creates pleasing, circular highlights and simulates depth of field effects. Adjust aperture shape, size, and brightness threshold.
Creates blur that radiates from a central point, either as a zoom effect or rotational blur. Good for implying movement or drawing attention. Choose between zoom or spin effects.
Preserves edges while blurring surfaces, useful for skin smoothing in portraits while maintaining detail in features. Adjust blur radius and threshold to control the effect.
Replaces each pixel with the median value of neighboring pixels. Excellent for removing noise while preserving edges. Adjust the blur amount to control the filter radius.
Edge-preserving blur that considers both spatial proximity and color similarity. Excellent for noise reduction and skin smoothing while preserving important details and textures. Adjust blur radius and edge threshold.
Simulates the selective focus effect of tilt-shift photography, keeping a strip of the image sharp while blurring the rest. Perfect for creating miniature effects with cityscapes or landscapes. Choose horizontal or vertical orientation.
Everything you need to know about our blur image tool
Image blurring is a digital image processing technique that reduces detail and noise in an image by averaging pixel values. Different blur algorithms produce different visual effects, from simple softening to complex depth-of-field simulations.
People blur images for various reasons: to create artistic effects, reduce noise, hide sensitive information, create a depth-of-field effect, soften imperfections in portraits, or create a background that doesn't distract from the main subject.
Gaussian blur applies a weighted average with pixels closer to the center having more influence, creating a smooth, natural-looking blur. Box blur (or Average blur) treats all pixels in the defined area equally, which is faster but can create more visible edges and a less natural appearance.
Motion blur is ideal when you want to convey a sense of movement or speed in a static image. It's commonly used for sports photography, vehicle images, or any subject that you want to appear in motion. You can adjust both the angle and intensity of the motion effect.
Lens Blur simulates the out-of-focus areas produced by camera lenses, creating pleasing, circular highlights known as 'bokeh'. It's perfect for creating professional-looking depth of field effects where the subject is sharp and the background is blurred. You can adjust the aperture shape, bokeh size, and highlight threshold to customize the effect.
No. This tool processes your image entirely within your browser. Your image is never uploaded to our servers, ensuring complete privacy and faster processing. This also means you can use the tool offline once the page has loaded.
Our tool supports all common image formats including PNG, JPEG, WebP, GIF, and BMP. You can also download your blurred image in PNG, JPEG, or WebP formats, regardless of the original format.
After applying a blur effect, you can press and hold your mouse button on the preview image to temporarily see the original image. This makes it easy to compare the before and after versions without switching between different tabs or windows.
