Tool usage guide
The Image Box Blur tool provides a fast, efficient way to soften images by applying a uniform averaging filter. By calculating the mean color value within a defined kernel size, this utility effectively reduces digital noise and creates smooth, artistic blur effects for your photos and graphics.
Background
A creator needs to share a screenshot that contains a visible email address.
Problem
The sensitive text needs to be obscured quickly without using complex editing software.
How to use
Upload the screenshot, select a 15x15 box size, and apply the blur to the specific area.
kernelSize: 15, iterations: 2Outcome
The sensitive information is effectively unreadable while maintaining the overall context of the screenshot.
Background
A designer has a sharp, busy background image that distracts from the foreground text.
Problem
The background needs to be softened to improve readability of the overlaying text.
How to use
Upload the background image, select a 9x9 box size, and choose the 'Normal' output mode.
kernelSize: 9, iterations: 1, outputMode: normalA box blur is a spatial filter that replaces each pixel with the average value of its neighboring pixels within a square box.
A larger kernel size covers more pixels for each calculation, resulting in a stronger, more noticeable blur effect.
Yes, you can use the 'Iterations' setting to apply the blur effect repeatedly, which creates a progressively smoother result.
The tool supports common image formats including JPEG, PNG, WebP, GIF, BMP, and TIFF.
Output modes like 'Enhanced' or 'Vintage' apply color and contrast adjustments to the blurred image to achieve specific aesthetic looks.
Outcome
The background is uniformly softened, creating a professional depth-of-field effect that highlights the foreground content.
