How To Change A File Type In Windows 10/11

If you need to change a file to a different format, Windows has built-in tools to do the job without needing additional software. This guide will show you how to change file types by renaming their extensions.

Important Preparation

Before proceeding, make a backup copy of the file to avoid losing any important data in case something goes wrong.

What is a File Extension?

A file extension is the last few characters after the final period in a filename. These characters determine the file type and tell the operating system how to handle the file. For example, a file named examplefile.txt is recognized as a text document. Changing the extension to .jpg will make it an image file, though the content must match the new format for it to work correctly.

Example of Changing a File Extension

Sometimes, software creates backup files and alters the extension slightly, such as changing .exe to ._xe. To restore the file to its original type, you need to change the extension back.
