How to Convert DOC to DOCX in Word for Mac Without Losing Formatting

Product: Microsoft Word
Device & OS: Mac
Scenario: A user needs to update a legacy DOC file provided by a publisher into the DOCX format for better compatibility and feature support.
Observed behavior: The user wants to successfully change the file format while ensuring that images, section breaks, headers, footers, and complex layouts remain perfectly intact.

Before you start

Verify that the publisher-provided DOC file is not restricted or marked as read-only, and open the document to inspect its original layout before conversion.

Solution 1Recommended

Use the Save As Feature in Microsoft Word for Mac

The standard and most reliable method to upgrade a legacy document format natively within Microsoft Word for Mac.

Using the built-in 'Save As' function allows Word to translate the older binary DOC format into the newer, XML-based DOCX format. While most text and images convert perfectly, it is highly recommended to manually review the file afterward, especially if it contains legacy macros.

Open the DOC File

Launch Microsoft Word on your Mac and open the publisher-provided DOC file you wish to convert.

Access the Save As Menu

Navigate to the top menu bar, click on 'File', and select 'Save As...' from the dropdown list.

Select the DOCX Format

In the Save dialog box, click on the 'File Format' dropdown menu and choose 'Word Document (.docx)'.

Save the Document

Choose your preferred destination folder and click the 'Save' button to create a copy in the new format.

Review the Formatting

Open the newly saved DOCX file and scroll through to ensure headers, footers, section breaks, and images are accurately preserved.

Use the Save As Feature in Microsoft Word for Mac

Macro Compatibility: If your original DOC file contains legacy macros, saving it simply as a DOCX will strip the macros. To preserve macros, select 'Word Macro-Enabled Document (.docm)' instead.

Frequently Asked Questions

Why do some elements shift when converting DOC to DOCX?

Older DOC files use a binary structure, whereas DOCX is XML-based. While standard text and images convert seamlessly, highly complex publisher layouts, custom spacing, or legacy drawing shapes may require minor manual adjustments after conversion.

Can I batch convert multiple DOC files to DOCX on my Mac?

Microsoft Word for Mac does not have a built-in batch conversion button. To convert multiple files at once, you would need to use a specialized third-party conversion tool or run an AppleScript.

Does converting a DOC file to DOCX reduce its file size?

Yes, DOCX is a ZIP-based XML format that is heavily compressed. Converting older DOC files to DOCX usually results in significantly smaller file sizes.
