Understanding Image Blurring

Obscure Sensitive Details

Soften or hide parts of a photo, such as license plates or background clutter, for privacy or focus.

Adjustable Radius

Control blur intensity from a subtle softening to a heavy, abstract wash with a single slider.

Native Gaussian Blur

Uses the browser's built-in Canvas filter API for a smooth, high-quality Gaussian blur.

Local Processing

Blurring happens entirely in your browser using the Canvas API — your image is never uploaded.

Blur Is Not Redaction

Blurring reduces visual clarity but does not securely remove information — in some cases, blurred text or faces can be partially reconstructed with enough effort. If you need to truly hide sensitive content, black out the area completely rather than relying on blur alone.

Key Takeaways

Adjustable Radius: Slide from a light softening effect to a heavy blur.
Full-Image Blur: The blur applies to the entire image uniformly.
Client-Side Only: All blurring happens locally in your browser — no data is ever sent to a server.
