How to add a line stroke, or border, to an image in Paint.net:
Open your image in Paint.net.
The image needs to have a transparent background for this to work.
Duplicate the layer (Ctrl + Shift + D).
Disable the top layer and select the bottom one to work with.
Select Adjustment then Brightness / Contrast, turn brightness all the way down and contrast all the way up.
Select Adjustment then Curves to set the color of the border. You can also use the Paint Bucket tool instead.
Select Effects then Noise then Median, turn Percentile all the way up and adjust the Radius to the width of the border.
If artifacts appear at or near the border, just fill them with the Paint Bucket tool.
Enable and select the top layer and merge it down (Ctrl + M).
You can now save the image as PNG file.
