Select a picture with a clear image. If the photo is blurry or does not have a clear subject, the program will not create as distinct a cartoon effect as it would with a crisp, clear picture. Portraits generally work best, but many of the programs can also adapt other pictures such as landscapes, although the effect is not as dramatic.
Choose a program that will turn your pictures into cartoons. Websites such as BeFunky, Cartoonize.net and My Web Face all offer free programs that do not require registration. Some of these programs can be downloaded, while others can be used directly from the website.
Upload your picture to the program. In every case, these programs will have a clearly marked "Upload" or "Select Image" option that will allow you to pick the picture you want to alter. Ensure that your picture is saved to an easily accessible location so you can find it easily when using the program.
Add additional effects. Programs such as BeFunky will also allow you to add speech bubbles, stickers, and other effects to your pictures to make them look more like a cartoon or comic book.
Select the button that will alter your photo. This is also labelled clearly, but the actual name will vary from program to program. After a few seconds you will be able to see a cartoon version of the picture you just uploaded. This picture can be saved if you are using a downloaded program, or downloaded off the website if you are using one that is web-based.
