Changing An Image's File Type Using Ifranview

Guide Overview

The purpose of this guide is to teach you how to change the file type (.jpg, .bmp, .gif, etc.) of an image file.
An images file type, tells you the type of compression used to make the image.
The compression type, determines the size of the image file. A .tif file uses very little compression, resulting in a large file size. On the other hand, a .jpg file uses heavy compression, which reduces file size.

A couple of reasons you might want to change an images file type:

• To reduce the file size for sending in an E-mail
  (see above)
  
• To make it compatable with a program you're using
  (say you have a .tga file, but the program you're using requires a .bmp file)

Well, enough with the boring lecture, let's convert a file.
