About the Blur Image Tool
This tool applies a Gaussian blur to your image — the same blur algorithm used by Photoshop, CSS filters, and most design software. A Gaussian blur works by averaging each pixel's colour with the colours of its neighbours, weighted by a bell-curve distribution. The higher the pixel radius, the stronger the blur effect.
Common uses: hiding sensitive information in screenshots (email addresses, phone numbers, faces), creating a dreamy or depth-of-field effect, softening background images for use behind text, preparing blurred thumbnails for progressive image loading, and generating placeholder images.
The tool uses your browser's Canvas API with the ctx.filter property to render the blur. Your image is never sent to any server — all processing is local.
The blur intensity slider lets you dial from subtle (radius 1–5) to heavy (radius 20+). Subtle blur softens a background or adds a slight dreamy effect. Heavy blur completely obscures recognisable content — faces, text, sensitive data. The download button exports the result as a PNG to preserve quality.
