If the file needed to remain at its original size, I could try compressing it instead File compression refers to the way in which data is stored or packed Just as different people can stuff more or less clothing into a single suitcase, different compression types can pack more or less data into a file Specific compression methods GIFs, JPEGs, and PNGs work best for web graphics The next few sections of this chapter discuss these file formats, and their compression methods, in further detail

Terminology
Before you dive into the actual file types, you need to learn a few terms that relate to web file formats
Compression Methods
Web graphic file formats take your original image and compress it, to make it smaller for web and e-mail delivery Two types of compression methods are used for web graphics:
Lossy Lossless
Lossy compression requires data to be removed permanently from the image to compress the file and make it smaller Typically, areas with small details are lost as the level of lossy compression is increased Lossless compression is the opposite of lossy, in that no data is lost when the file is compressed In these cases, the actual data looks the same whether it s compressed or uncompressed

Resolution
In a previous chapter, you learned about monitor resolution, but in this case I m referring specifically to file resolution Whenever you create or edit a file in a graphics editor, you need to specify a file resolution (see Figure 14-4) The standard file resolution for web graphics is 72 pixels per inch (ppi)
NOTE
Don t be confused if you see dpi (dots per inch) used interchangeably with ppi Technically speaking, dpi is more often linked to a printer s dots per inch, while monitors are considered to have pixels per inch
Transparency
When you view an image and are able to see through parts of it, that image is said to have transparency Some graphics editors show this transparency by displaying a gray and white checkerboard behind the image Figure 14-5 shows an example of this in Paint Shop Pro When a web graphic contains transparency, the page s background color or background tile shows through in the transparent areas File types that support transparency fall into two categories: binary and variable Binary transparency means any given pixel is either transparent or opaque Variable transparency, also known as alpha channel, allows pixels to be partially transparent or partially opaque; therefore, it is capable of creating subtle gradations Certain file types don t support transparency If the image shown in Figure 14-5 were to be saved in a file format not supporting transparency, the areas shown in a checkerboard would be filled in with a solid color
