How to use this page
- Choose an image.
- Set a radius: low for a light soften, higher for a wash of colour.
- Blur, inspect at full size, and download. Keep the sharp master.
Worked example: a soft hero behind white type
Resize to the hero width, blur until the subject no longer competes with the heading, then export. If you need a blocky look instead, use the pixelate tool.
What this job is for
The same radius looks weaker on a large photo than on a small one. Judge the preview, not the number alone. Resize to the final canvas first when the blur is for a specific slot.
Useful limits
Low blur can leave faces and text readable. Hidden pixels are not a privacy control.
The live tool behind this page is Blur Image. It is the same local engine as the rest of Image Cosmos.
