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.

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.

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. Here’s how to do it.

Note: For demonstration purposes, we will be using a .pdf file with Adobe Acrobat PDF Reader.

Step 1: Go to the relevant folder and open the target file.

Step 2: Then, click on the File options.

Step 3: Here, click on Save As.

Step 4: Then, select the format you want to save the file as.

This will convert the file type and save it according to your preference.

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.

1. Change File Type for an Individual File

Step 1: Right-click on the Windows icon and select Terminal.

Step 2: Click on the down arrow once the Terminal opens and click on Command Prompt.

Step 3: Then, go to the folder that has the file and right-click on it.

Step 4: Here, click on ‘Copy as path’.

Step 5: Now, go to Command Prompt and type the following command:

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

Step 6: Press enter. This will open a new line with the file name.

Step 7: Here, type the following command and press enter.

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.

This will change the file format for the individual file.

2. Change Multiple File Extensions at Once

Step 1: Go to the folder that has the file and right-click on it.

Step 2: Then, click on ‘Copy as path’.

Step 3: Now, right-click on the Windows icon and select Terminal.

Step 4: Here, click on the down arrow and click on Command Prompt.

• 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.

4. Using Online Converters to Convert Your File

You can use other third-party tools like Online-Convert and Could Convert to convert the file types for your video, text, and image files respectively.
