You can create your own customized avatar by visiting a website that hosts an avatar maker. Several popular makers are DoppelMe.com, PickAFace.net, SP-Studio.de and FaceYourManga.com. All of these makers are free and require no registration to use.
Making an avatar at each of these sites is easy. When you click on the generator, you start with a bare-bones version of your avatar. From there, you have the option to customize this avatar by adding skin tones, facial features, hair style, clothing and fashion accessories. When you're done, the avatar maker asks you to click on a button or link to generate a final .JPG, .PNG or .GIF file that you can download to your computer.
If no such button or link is available, an alternative is to take a screen shot of your finished avatar and save it to your hard drive. For PC users, press the Print Screen key on your keyboard, paste the screen shot into the paint program of your choice (such as MS Paint), crop the image down and save it as a .JPG, .PNG or .GIF file. For Mac users, press Command+Shift+4, then select your avatar by clicking and dragging your mouse to draw a box around it. This action automatically crops the image and saves it as a .PNG file.
