Question details

The user needs to recover an original PDF file that was overwritten and replaced by a DOCX copy when opened and converted in Microsoft Word via OneDrive.

How to Stop Word from Replacing the Original PDF When Converting from OneDrive

Product: Microsoft Word / OneDrive
Device & OS: not provided
Scenario: Opening and converting a PDF file stored in OneDrive using Microsoft Word.
Observed behavior: Instead of creating a new converted DOCX copy, Word and OneDrive sync issues cause the original PDF file to be replaced entirely by a Word document with the exact same name.

Before you start

Before attempting to recover your file, temporarily pause your OneDrive synchronization from the system tray to prevent any further overwriting of your cloud files.

Solution 1Recommended

Restore the PDF via OneDrive Version History

Use OneDrive's built-in version control to recover the overwritten PDF, and prevent future issues by manually saving the converted file under a different name.

When OneDrive syncs an aggressively overwritten file from Word, the original format is usually preserved in the cloud's version history. Restoring this previous version is the fastest way to get your PDF back.

Access Version History

Open File Explorer, locate the overwritten Word document in your OneDrive folder, right-click it, and select 'Version history' (or do this via the OneDrive web interface).

Restore the Original File

Look through the list of previous versions for the entry matching the date and time before the conversion. Click the three dots next to that version and select 'Restore' to revert it back to a PDF.

Save Converted Files Safely

In the future, immediately press F12 (Save As) upon opening a PDF in Word. Save the new DOCX file with a different filename or in a completely separate folder before OneDrive begins syncing.

Keep Local Backups: Always keep a local copy of important PDF files on your computer's hard drive before opening them with Word's PDF conversion tool.

Frequently Asked Questions

Why does Word overwrite my PDF when opening it from OneDrive?

This happens due to a conflict between Microsoft Word's PDF Reflow feature and OneDrive's AutoSave function. Instead of saving the converted DOCX as a separate entity, AutoSave sometimes aggressively syncs the new format over the original file path.

Can I recover a PDF if it was deleted instead of overwritten?

Yes. If the PDF was deleted rather than overwritten, log into your OneDrive account online and check the Recycle Bin. Deleted files are retained there for 30 days for personal accounts before permanent deletion.

How can I safely convert PDFs in Word without risking my original file?

To be safe, always copy your original PDF to a non-synced local folder (like your desktop) before opening it in Word. Once Word converts it, use 'Save As' to create the DOCX file, then move it back to your OneDrive folder.
