Image Blur Tool
Blurring softens detail. Designers use it for backgrounds behind text, and it can hide small text in a screenshot. This tool applies a smooth blur to the whole image using a radius you choose.

Frequently Asked Questions
Can I blur only part of an image?
This tool blurs the entire picture. To hide one region, crop it out or use an editor with a selection tool.
Is blur a safe way to hide sensitive text?
Light blur can sometimes be reversed or read. For anything sensitive, cover the area with a solid block instead.
