Fix Word for Mac Cannot Open or Convert PDF to DOCX
Question details
The user needs to resolve an issue where Word for Mac fails to open and convert previously compatible PDF files to editable DOCX formats.
- Product
- Microsoft Word for Mac
- Device & OS
- macOS
- Scenario
- Attempting to open a standard PDF file in Word for Mac to automatically convert it into an editable Word document.
- Observed behavior
- Word displays an error stating 'the PDF document could not be opened', completely failing to convert or load the document.
Ensure your Mac is running the latest version of macOS and back up any original PDF documents before attempting format conversions or software reinstallations.
Re-save the Document as a Tagged PDF
Exporting the original file as a tagged PDF often resolves underlying structural and format compatibility glitches that block Word for Mac from parsing the file.
A tagged PDF contains structural metadata that defines the document's layout and reading order. This extra data helps Microsoft Word's conversion engine accurately interpret complex elements.
Open the original source document (e.g., Pages, another Word doc, or the original PDF viewer) on your Mac.
Navigate to 'File' in the top menu bar and select 'Save As' or 'Export'.
Choose 'PDF' in the File Format dropdown box.
Ensure you give the file a completely different name from the original document, then click 'Export' or 'Save'.
Launch Word for Mac and attempt to open this newly created tagged PDF.
Completely Uninstall and Reinstall Microsoft 365
If saving as a tagged PDF does not work, the Microsoft 365 installation on your Mac may be corrupted and requires a clean reinstall.

Frequently Asked Questions
Why does Word for Mac say 'the PDF document could not be opened'?
This error generally occurs due to missing or corrupted structural data in the PDF file, corrupted Microsoft Office preferences, or complex graphical elements that Word's conversion engine cannot parse.
What is a tagged PDF and how does it help conversion?
A tagged PDF includes hidden structural metadata that defines the exact reading order and document elements (such as paragraphs, headings, and tables). This structure gives Word for Mac the necessary blueprint to accurately translate the file into an editable DOCX.
Will I lose formatting when converting a PDF to a Word document?
While standard text and basic layouts usually convert seamlessly, complex designs with multiple overlapping images, columns, or unique embedded fonts may shift. Using a specialized PDF to DOCX converter minimizes these formatting discrepancies.
Are there alternative ways to convert a PDF to DOCX without MS Word?
Yes, you can use comprehensive office suites like WPS Office which feature robust, built-in PDF to Word conversion tools that operate independently of Microsoft Word's engine.
