If you do not plan on saving screenshots of the games

TGA is a bitmap file format for storage of 8, 15, 16, 24 and 32-bit true-color images. It can be used for creating climate maps and for saving screenshots of the games rather than something more common. This format does not allow storing as many details as the TIFF format. And it is not as widely supported as PCX or TIFF. Besides, if you plan on sharing TGA images with someone else, you'd better convert them to bmp or jpg for portability. Since TGA format is not widespread, and Windows may not recognize TGA files without proper software, your friends and family probably won't be able to open them. With ImageConverter Plus you can convert images in TGA format into various other formats depending on your preferences.
