Image Blur: what it does and when to use it
The Image Blur tool offers three kinds of blur. Gaussian blur softens everything evenly, which is how you make a busy background calm behind text or blur a whole screenshot. Motion blur smears the picture in one direction to suggest speed. Radial, or zoom, blur streaks outwards from the centre, as if the camera zoomed during the exposure.
Keep the centre sharp turns any of them into a focus effect: the middle stays crisp and blur increases towards the edges. With a narrow sharp band this becomes a tilt-shift look that makes real scenes look like miniature models, especially when photographed from above.
Blur is not a safe way to hide sensitive text such as passwords, account numbers or addresses, because light blur can sometimes be read or partly reversed. Use Pixelate & Censor with a solid box, or crop the information out. To blur only the background behind a person automatically, use Portrait Blur.

How do I blur a face or a number plate in a photo?
Blur or pixelate only that area. For hiding information, the Pixelate and Censor tool is safer: strong pixelation cannot be undone, while a light blur on text can sometimes be partly read.
How do I blur the background of a photo?
For a portrait-mode look where the subject stays sharp, use Portrait Blur, which finds the subject with AI. This tool blurs the whole frame or its edges, which suits a soft, dreamy look or a background image for text.
What is motion blur used for?
It adds a sense of speed, as if the camera or subject moved during the shot. Set the angle to match the direction of movement. Related tool: Image Sharpener.
