Solution 1Recommended

Use the 'Export' Feature as a Workaround

Bypass the standalone 'Document to PDF' tool by opening the file directly and using the export function.

Since the Files app control is disabled in the dedicated PDF tool, you can achieve the exact same result by opening the document first and then exporting it as a PDF from within the viewing interface.

1
Locate the Document

Open the native iOS 'Files' app and locate the Word document you want to convert.

2
Open in Microsoft Office

Tap the document to open it. If it doesn't open in Office by default, long-press the file, tap 'Share', and select the Office app.

3
Export to PDF

Once the document is open in the Office app, tap the three-dot menu (More options) in the top right corner, select 'Export', and then choose 'PDF'.

Use the 'Export' Feature as a Workaround
Workaround Successful: This method effectively converts your document to PDF without relying on the bugged file-selection menu.
