Blur Image Tool

Apply a Gaussian blur to any image with a configurable radius, and download the result as a PNG. Blur is useful for creating background images, obscuring sensitive content, generating placeholder visuals, and adding depth-of-field effects to flat compositions.

Frequently Asked Questions

What is blur radius and what values should I use?
Blur radius controls the spread of the blur effect in pixels. Small values (1–5px) create a subtle soft focus. Medium values (10–20px) produce a noticeable blur suitable for background effects. Large values (30–40px) create heavy blur useful for obscuring content or creating stylized effects.
Can I use this to hide faces or sensitive information?
The tool blurs the entire image, not specific regions. For full privacy protection of faces or text in an image, a region-specific blur tool would be more appropriate. For light obscuring, the blur tool works, but determined viewers may still be able to make out content under moderate blur.
Is my image uploaded to a server?
No. Processing happens entirely in your browser using the Canvas API. Your image never leaves your device.
