For more details on screenshots see this article on screenshot options. Nevertheless, screenshots have their uses and can be particularly useful for illustrating aspects of what you see on screen. In addition, screenshots are limited to what you see on screen, so if you have a well-formatted document that goes beyond the limits of the screen, then you cannot capture it in an image file using screenshots. If you print the file or wish for finer detail of the text by having higher resolution, you can't do this with a direct screenshot. This cuts down on file size, but it also limits the uses of the file to being presented on screen. While screenshots are useful and convenient, they're limited primarily because the screen resolution on Macs is 72 dots per inch, which means the resulting picture will also be 72 dots per inch. You can then import the resulting image (by default it's a PNG file) into numerous applications. The first is the use of screenshots, which is an excellent way to quickly snap a sample picture of the screen, a window, or a selection of the screen. Sometimes programs may specifically support saving to a JPEG, TIFF, or other rasterized format, but since many don't you can take advantage of a couple of technologies built in to OS X that will allow you to do this. There are a couple of ways to save documents to an image format. Not only does converting a text file to an image allow for easier handling when embedding in other documents, but it also allows for easier drawing of annotations and other items on the document when discussing and presenting it.

I was recently asked how to do this by a Mac user, who was looking for a way to better manage a text document for presenting it in Web pages, but who was also interested in placing a formatted text file as an object in presentations and other Word processing documents. Sometimes when managing word processing or text documents you might want to save the file in a compressed JPEG format or other similar picture format.
