How to Change File Type on Windows 11

Once the file extension is visible for all the files, we can now proceed with changing the file type. As mentioned above, there are three major ways you can convert file types in Windows 11. Let’s have a detailed look at them all.

Method 1: Rename the File

When changing the file type using the rename option, all you need to do is select the file and change the name of its extension. Follow the below steps to do it. Ensure the before and after file extensions are similar to each other or your file might get corrupted. Here’s how to do it.

Step 1: Open the relevant folder and click on the file. Click the Rename icon.

Step 2: Rename the extension.

Step 3: Then, click on Yes. This will change the file type.

Once done, try opening the file again to check. This should especially be done when converting video files as they might change their file extension name while still retaining their original extension characteristics.

Method 2: Using the Save as Option to Convert File Extension

With the save as option, you can simply open the file extension in the relevant software. Then, using the Settings menu, save the file again, but this time in a different format. For demonstration purposes, we will be using a .pdf file with Adobe Acrobat PDF Reader. Here’s how to do it.

Step 1: Open the relevant file in Adobe Acrobat PDF Reader and click on File.

Step 2: Here, click on Save As.

Step 3: Select the format you want to save the file as.

Step 4: Select the folder you want to save the file to and click on Save. This will convert and save the file.

Method 3: Using Command Prompt

The third and last way to change the file type on Windows 11 is by using the Command Prompt. Here, you can either change the file extension for individual files one by one or change multiple file extensions at once. Here’s how to do it.

I. Change File Type for an Individual File

Step 1: Go to the relevant file and right-click on it. Click on Copy as path.

Step 2: Now, open Command Prompt, type the following command, and press enter.

cd /d "name of the folder path copied eariler"

Step 3: Here, type the following command and press enter. This will change the file format for the individual file.

rename "file-with-extension-1" "file-with-extension-2"

Note: Replace file-with-extension-1 with the file name and its original extension followed by the file name and the extension you want to convert it in.

II. Change Multiple File Extensions at Once

Step 1: Go to the relevant file and right-click on it. Click on Copy as path.

Step 2: Open Command Prompt, type the following command, and press enter. This will open a new line with the file name.

cd /d "name of the folder path copied eariler"

Step 3: According to your requirement, type any of the below-mentioned commands and press enter.

• For converting multiple files within that same folder:

rename *.fileextension1 *.fileextension2

• For converting multiple files while saving a copy of the original:

xcopy *.fileextension1 *.fileextension2

• For converting multiple files regardless of what their original extension is:

ren *.* *.newfileextension

• For converting multiple files for all the sub-folders in that folder:

for /R %x in (*.extension1) do ren "%x" *.extension2

Once you press enter, the command will be executed accordingly. Now, go to the relevant folder and check if the changes have been made.
