First you'll need to choose a photo of yourself that you would like to mak into a cartoon avatar. This photo should clearly show all of your facial features. Don't choose a photo that is dark, washed out with a flash, grainy, or blurry.
Convert your photo to digital format. If your photo is already saved as a photo file on your computer (usually a .jpeg) you are ready to move on to the next step. If your photo is in a different format, or if you only have a printed version, you'll need to scan it onto your computer using a scanner, or take a new photo using a digital camera or a built-in camera on your computer.
Select a website that will change your photo into a cartoon. All you wil need to do is submit your photo to the website by uploading it. Many of these websites have been created and some of them charge a fee, but most will provide the service for free. Take the time to explore each of these websites and have. You will find a wide variety of different styles and quality. You don't have to commit to using any certain website so feel free to see what they offer. You can also make yourself into a cartoon at more than one site, so have fun and see what you can come up with. You will soon have the coolest avatar out there.
