You may need to convert a file to a different format, and this is when you’ll need to modify the file’s extension. A typical scenario is switching from test.png to test.jpg. Typically, the letters that come after the (full stop) in a file name indicate the file extension or format of the file. The “test” file shown above may be downloaded as either a.png or.jpg file.
Sometimes it becomes necessary to change the file extension to different formats such as .rtf,.txt, and much more. You can easily change the file extension in Windows 10/7/8 by following these simple steps. There are many possible ways to change, offline or online, but offline is much more straightforward.
