Uses for a blurred image
Blurred photos make great backgrounds for slides, website headers and social posts because text stays readable on top of them. Blurring is also a quick way to hide sensitive details like faces, number plates or screen contents.
Is blurring safe for hiding information?
A strong blur hides most details, but for passwords, ID numbers or other sensitive text, the Pixelate tool with large blocks is the safer choice, because light blurs can sometimes be partially reversed.
Frequently asked questions
Can I blur only part of an image?
This tool blurs the whole image. To hide a specific area, pixelate or crop the image instead.
Does blurring reduce file size?
Often, yes. Blurred images contain less fine detail, so JPG and WebP files usually become smaller.
Which formats are supported?
JPG, PNG, WebP, GIF and BMP. JPG, PNG and WebP keep their format; others are saved as PNG.
