Image Blur Tool

Summary

The Image Blur Tool lets you apply a smooth Gaussian blur to any photo directly in your browser — no account, no upload, no waiting. Simply choose an image, set the blur strength with the slider, and preview the result in real time. When you are happy with the effect, download the finished PNG in one click.

How it works

1. The image is drawn onto an invisible HTML5 Canvas element.
2. The CSS filter: blur() property is applied to the canvas context with your chosen radius.
3. The filtered canvas is composited and exported as a PNG data URL.
4. The download link is generated client-side, so nothing touches a server.

Use cases

• Create blurred backgrounds for UI mockups and graphics.
• Create depth-of-field background effects for presentations.
• Soften an image for use as a website hero background.
• Generate soft backdrop wallpapers for video or slide presentations.
• Generate blurred thumbnails or placeholder images.
• Reduce visual noise in busy photos for overlay text.
