Step 1: Open
a Microsoft PowerPoint and add
a blank slide as shown
below.
Step 2: Draw or write whatever you want for your logo using
different shapes and word
art. As I draw below.
Step 3: Select all > Right Click > Group> Group. As shown below
Step 4: Now Right-click on that image and select Save As Picture
Save the picture in any folder and you can use that logo anywhere you want. The most important thing is the background of that image is transparent so that it can fit on any background.
