Review Document Saving and Export Workflows

Check the specific application or workflow you are using to ensure it is not defaulting to PDF format.

Microsoft Word does not automatically convert documents to PDF natively. This behavior usually occurs due to a specific workflow, such as an email client automatically converting attachments, or a third-party software initiating an export process.

1
Check Save As format

When saving a document, go to 'File' > 'Save As' and ensure the 'Save as type' dropdown is explicitly set to 'Word Document (*.docx)' and not PDF.

2
Review automated scripts or tools

If you are using a third-party document management system or macros, review their settings to ensure automatic PDF export is disabled.

3
Check sharing preferences

When emailing a file from directly within Word, confirm you are selecting 'Send as Attachment' (which sends the .docx file) rather than 'Send as PDF'.

Note on Subscriptions: If you have an 'Export PDF' subscription from Adobe, remember that this tool is designed to convert PDFs into Word or Excel files, not the other way around. It will not cause Word files to automatically become PDFs.
WPS Office Document Control

Take Full Control of Your File Formats with WPS Office

  2. 2. Save in its native format: Click 'Menu' and select 'Save' to keep your document securely in the .docx format.
  3. 3. Convert to PDF manually: When you are completely ready to create a PDF version, navigate to the 'Tools' tab and explicitly click 'Export to PDF'.

Frequently Asked Questions

Will an 'Export PDF' subscription automatically convert my Word files to PDF?

No. An 'Export PDF' subscription is typically utilized to convert existing PDF files into editable formats like Word or Excel. It does not run in the background to automatically convert your Word files into PDFs.

Why do Word documents I download from my email automatically open as PDFs?

This usually happens due to browser settings or active browser extensions that convert or preview documents as PDFs. Disabling document-viewer extensions in your browser settings will typically resolve this.

How can I tell if my Word file was actually converted or just opened in a PDF viewer?

Check the file extension at the end of the file name. If it ends in .docx, the file is still a Word document but your computer is mistakenly using a PDF program to open it. You can fix this by changing your default 'Open with' file associations.
