How to Change File Extension(s) on Windows 10/11?
File extensions are the last characters appended to file names that serve to identify the type of file and specify which applications are able to access and work with it. For example,
.txt
files are typically opened by text editors, while
.jpg
files are opened by image viewers. There are various reasons why you might need to change file extensions:
- Compatibility : Some programs require specific file extensions to recognize and open files correctly.
- Organization : Changing extensions can help categorize and organize files more effectively.
- Conversion : Although not a true conversion, changing an extension might allow a file to be recognized by a different application that supports the format.
This article will cover different methods to change file extensions on Windows 10 and 11.

Example: Change a .png file to .jpg format(Be cautious when changing file extensions, as incorrect extensions can render files unreadable by their associated applications).
Method 2: Open File and Save As
Another straightforward method to change a file extension is by opening the file in an application and saving it as a different type.
- Open the file in the application that supports the current file type.
- Click on File in the menu bar.
- Select Save As or Export .
- In the dialog box, choose the desired file format from the drop-down menu.
