There are many different graphic file formats that you can use to save images on your personal computer. These include: TIFF, JPEG, GIF, PNG, TARGA, and ICO. Each of these formats has its own pros and cons, and one is not necessarily better than the others. Instead, they each have their own situations that they are best suited for. The most used ones include JPEG, GIF, and PNG. The others are not used nearly as often.
Perhaps one of the oldest and most widely used graphic file format is GIF, or Graphic Interchange Format. GIF images use a palette of 256 colors, because of this they usually have a small size and are great for background images for websites. You can also make GIF images transparent quite easily which can make them even better suited for backgrounds. However, people who create programs using GIF images are required to pay licensing fees. It is because of this that PNG images were created.
The PNG graphic file format, or portable network graphics, was created as a patent-free answer to the GIF format. In all actuality however, it is superior to GIF in many ways. For example, a PNG file can be compressed by 5 percent to 25 percent more than a GIF image can. PNG images can be made transparent as well, and the user also has better control over how transparent the image becomes.
Finally, there is the JPEG format, which stands for Joint Photographic Experts Group. These images are created in such a way that they may be compressed to 1/10 of their original size. When JPEG is used for print design, it is recommended that you save it at 100 percent quality however, so that the end product looks as nice as possible. JPEG compression is much more noticeable once it has been printed out than it is while it is still onscreen.
