How to Convert a Doc File to a Docx File

Using Word

Open your Doc file in Microsoft Word. Find and double-click your document to open it in Word.

Click the File tab on the top-left. This will open your file options on a drop-down menu. On Windows, this button is next to Home in the upper-left corner of Word. On Mac, it's on your menu bar in the upper-left corner of your screen.

Click Save As on the File menu. This option will open a new dialogue box. You can save your document in a different, compatible file format here. If this doesn't automatically open a new dialogue box, click Browse on the Save As page.

Click the format drop-down at the bottom of the Save As window. This will open a list of all the available file formats you can use. On Windows, this menu is labeled as Save as type below the File name field. On Mac, it's labeled as File Format at the bottom.

Select Word Document (*.docx) as your file type. This will allow you to save a separate copy of the same document in Docx format.

Select a saving location for your document. Find the folder where you want to save your Docx document, and click on the folder name to select it.

Click Save on the bottom-right. This will save a copy of your document to the selected location. Your new document will be saved in Docx format.

Click the Upload tab in the "Open a file" window. You can find it at the top of the pop-up window.

Click the blue Select a file from your computer button. This will allow you to select and upload the file you want to convert.
