Your image is ready to post. If you want to control the "blur" intensity, drag your selection a little further or closer in the initial resize.

Remember that Paint 3D does not blur an image directly; it lets us pixelate the image and reduce its quality. When you bring back the selection to its original size, it will look blurred. If you want more control over how you blur your images, we recommend using free photo editing software.
