Open the software and under the "File" menu choose "Open" to browse for the folder where the image you want to turn into a cartoon is located.
Apply the cartoon effect to your photographic image. The software will immediately render the photo as a cartoon.
Edit the cartoon by going to the "Effects" menu and adjusting the texture appearance and coloring of the cartoon until it fits your needs. You can also add text to turn the cartoon into a comic.
Select a website that features web-based tools for converting your photographs to cartoons (See Resources).
Upload the photo you want to convert to a cartoon. Apply cartoon and other drawing effects to your image using the graphic tools. You can color your images to look like comic book art or turn them into rough pencil sketches with just a few clicks. Simply follow the on-screen directions.
You can also choose a cartoon template scene from the wide variety available and upload your photo. The photographs you upload will be placed in the scene template you selected, allowing you to make cartoons featuring you and your family and friends.
