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.

Why change the file extension?

One typical example of changing your file extension is that sometimes your computer does not support the format of your existing file, so you need to change the file extension. You may also need to change the file extension when the file format you are uploading may show an error. For all these purposes, different file extensions are required.

How to see the existing file extension?

For Windows 7 or Windows Vista: Open the file you wish to change its extension in File Explorer (for this, just type “folder option’ after opening the Windows logo button). Go to the organize option and tap the folder and search option. Now tap on the View tab and uncheck Hide extensions for known file types. 

In Windows 8, to change how File Explorer displays files, choose the View menu. You may inspect file extensions by checking the box next to the option.

For Windows 10: Open the desired file in File Explorer (just type ‘file explorer’ after opening the Windows logo button). Now tap on the view tab and check or enable File name extensions.
