The original AI file is still loaded in Illustrator's workspace, so any unsaved changes would need to be saved ( Ctrl + S or Command + S on Mac) before closing the program. You can have as many artboards in a project as you like and you can stack them side by side or in a vertical. Now you should have two versions of the character's business card in their respective locations, one as AI format and one as PNG format. Its a fancy name for your workspace or page. In the PNG Options window that pops up next, change the background color to White if it is not that already. Choose a convenient location to save the image, then click Export. Leave the name how it is and choose 'PNG (*.PNG)' from the 'Save as type' drop down menu ('Format' drop down menu on Mac). These buttons are most useful when you have multiple artboards on a single file that you would like to export at the same time. Check the 'Use Artboards' box and leave 'All' checked. The Export window will pop out, which gives you the opportunity to choose the new file's name, destination, and format. For now, you will learn how to save illustrations as PNGs.
Common formats that are used on the web are JPEG or PNG, though other formats are also used. When you complete an illustration in the future, you will likely have to save the file in a format other than Adobe Illustrator (.ai) so other people can view your work without having to use the Adobe Illustrator program.
