What is Image Blur?
Image blur is a photo editing technique that softens or obscures parts of an image by averaging pixel colors over a radius. It's widely used in portrait photography for depth-of-field effects, in social media to protect privacy, and in creative photography for artistic expression.
Types of Blur Effects Explained
Gaussian Blur is the most popular blur type, producing a smooth, natural-looking softness. Box Blur is computationally simpler and creates a uniform softening. Motion Blur simulates camera movement, adding a sense of speed and direction. Pixelate/Mosaic blur creates a retro pixel art look and is the standard technique for censoring content.
Blur Background Online for Professional-Looking Photos
A blurred background helps your subject stand out by creating a shallow depth-of-field effect similar to a wide-aperture lens on a DSLR camera. With our background blur mode, you can achieve this professional bokeh look with any photo, directly in your browser.
Protect Privacy with Selective Image Blur
Need to blur a face, license plate, or phone number before sharing a photo? Use our selective blur mode to draw precisely over any area. Choose rectangle or ellipse selection shapes for flexible censoring of personal or confidential information.
