Create Rounded Corners With Paint.NET

So you want to do rounded corners using Paint.NET? You must learn how. I mean your web site would be so not in style without images with rounded corners! I’m going to show you the easiest method I know about. I think it’s easier than using Photoshop to do it.

Here we have a nice picture of downtown Chicago. I want to give it rounded corners.

Picture Before

First I want to add a new layer by clicking Layers > Add New Layer.

Add New Layer

Now select the Rounded Rectangle Tool. The color doesn’t really matter.

Rounded Rectangle Tool

In the upper left corner, select to Draw Filled Shape.

Draw Filled Shape

Draw the rounded rectangle over the area you would like to keep for your rounded corners image.

Make Rounded Square

Use the Magic Wand to select the area of the rounded rectangle.

Use Magic Wand

Click Edit > Invert Selection.

Invert Selection

Now the area outside of the rounded square will be selected.

Selection Inverted

Select Layers > Delete Layer to delete the layer we made our rounded square on.

Delete Layer

The area outside of the rounded square will still be selected.

Layer Deleted

Simply press Delete on your keyboard and you are left with your image, now with rounded corners.

    Just use GIMP, its a more featured free editor in my opinion and allows you to adjust exactly how rounded your corners are :)

    does anyone know how to get the corners even more round? This was very useful but the corners are still a little sharp. I’m wanting a more rounded look!

    Bob’s tip is really good too !

    To get smooth round corners and even more!
    - make a white layer with a black rounded rectangle (or circle or whatever!)
    - add your photo on a new layer, it will appear in the top layer
    - in the layer window, select this top layer and show the properties.
    - then you can select blending mode = lighten

    This results in your photo having nice rounded corners and smooth without jagged or having to manually blur it.
