How It Works

Upload an Image

Drop in the image you want to blur.

Set the Blur Strength

Drag the slider until text is unreadable or the background is soft enough.

Download

Download the blurred image as a PNG.

Share Safely

Names, emails, and account numbers end up in screenshots constantly. A strong blur makes them unreadable before the image leaves your machine.

FAQ

Is Zight's image blur tool free?

Yes, completely free. No account or credit card is required.

Are my files uploaded anywhere?

No. This tool runs entirely in your browser — your files are processed on your own device and never uploaded to a server.

Can I blur just one part of the image?

This tool blurs the whole image. For region-by-region blurring and redaction, Zight's desktop app has a full annotation toolkit.

Is blurred text recoverable?

At high blur strengths, no — but for truly sensitive data, cropping or covering it with a solid box is the safest option.
