Frequently Asked Questions

What blur effects are available?

Three effects: Gaussian blur for smooth, natural blurring. Pixelate for a blocky, low-resolution look. Mosaic for a tiled pattern effect. Each has an adjustable intensity slider.

Can I blur only part of an image?

Yes. Switch to Region mode and draw rectangles on the areas you want to blur. This is perfect for hiding faces, license plates, sensitive text, or other private information.

Is the blur reversible?

Once downloaded, the blur is permanent. However, while editing you can use Edit Again to return to the editor and adjust the blur settings before downloading.
