Blurring an image has many uses — hiding sensitive information, creating professional background blur effects, or simply softening an image for artistic reasons. ImageZen4u applies a Gaussian blur entirely in your browser.
Common reasons to blur an image
- Hiding faces, names, or licence plates before sharing
- Creating a depth-of-field effect (sharp subject, blurred background)
- Making a background image less distracting for overlaid text
- Creating a frosted glass effect in UI design
