Image Blur Tool

Summary

Upload an image, drag the blur slider to set the radius, then download the blurred result instantly — no uploads to any server.

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

• Blur sensitive text or faces in screenshots before sharing.
• Create depth-of-field background effects for presentations.
• Soften an image for use as a website hero background.
• Anonymize personal information visible in photos.
• Generate blurred thumbnails or placeholder images.
• Reduce visual noise in busy photos for overlay text.
