Cut and paste circular pieces of photographs

Hi all,

I have a picture and I used photoshop's elliptical marquee tool to create a circle. I used the circle and cut and paste so that I have a circular chunk of the photograph.

However, when I copy and paste the circular patch into MS Word or PowerPoint, I get a WHITE rectangular box surrounding the circular photograph. It's ugly. How do I get rid of the box?

I'm not an expert but i think it's white because that is the size of your canvas (not the image size which is different and you saved it in jpg format.) on photoshop select the circle.
Select > inverse and press delete.

This will get rid of the white part but unless you reduce the canvas size and make it the same as the image size there'll be a background when saved as jpg.

Go to image > image size > check the size of your image.
go to image> canvas size > enter size of your image.

Or to make your life easier... and if MS word allows you to. After removing the white background save the image as PNG. that should keep the transparency.
