Image Blur
Apply an adjustable Gaussian blur effect to your images with custom radius settings and preserved dimensions.
Run tool
Smooth image details, soften visual elements, or soften backgrounds by applying a Gaussian blur filter to your graphics. This tool processes uploaded image files and applies an adjustable blur intensity across the entire canvas. You can upload standard image formats and specify a custom blur radius value to control the strength of the smoothing effect.
The default blur radius is set to 5.0, offering a balanced smoothing effect for common design tasks. Setting a smaller radius value creates a subtle softening, while larger numbers produce a heavily blurred, abstract appearance. If you enter a radius value below 0.1, the tool automatically adjusts it to the minimum threshold of 0.1 before processing.
When image processing completes, the tool returns the blurred graphic file while retaining your source format whenever possible, falling back to PNG if the source format is not detected. The result also displays the original pixel dimensions of your image for quick verification.
Instructions
- Upload an image file from your device using the file selector.
- Enter a blur radius number or keep the default value of 5.0.
- Click the run button to apply the Gaussian blur filter.
- Review the blurred image output and verified pixel dimensions in the result area.
Examples
- Upload a 1920x1080 JPEG photo, set the blur radius to 12.5, and run the tool to obtain a softened background image matching the original dimensions.
- Upload an avatar graphic and apply a light blur radius of 2.0 to soften sharp edges while keeping the original dimensions.
FAQ
What happens if I enter a blur radius below 0.1?
Any radius value below 0.1 is automatically raised to 0.1 before the Gaussian blur is calculated.
Which image format will the output use?
The tool preserves the detected image format of your uploaded file. If the format cannot be identified, the blurred file is output as a PNG.
Why did the blur operation fail to produce an image?
Processing cannot proceed if no image file is provided or if the uploaded file is corrupted and cannot be decoded as a valid image.
