Blur an Image Online
A smooth, even blur for backgrounds, placeholders, spoilers and privacy — without the dark halo other tools leave around the edges.

Blur Image — how it works
Blur a whole image smoothly — clean edges, any strength.
Clean edges
Most quick blur tools blend the border of the image with transparency, leaving a dark or faded frame. Here the edge pixels are extended outward before blurring and cropped back afterwards, so the blurred image fills the frame right up to its edges.
Common uses
Soft backgrounds behind text and UI, blurred placeholders while images load, hiding spoilers or private details, and creating a frosted backdrop for slides and social posts.
Scales with your image
The blur radius is relative to image size, so a 4000-pixel photo downloads with the same look as the preview instead of looking barely blurred.
