Fix Adobe Fill & Sign iPhone App Not Opening Word Documents
Question details
The user is unable to open or select Microsoft Word (DOCX) files to fill and sign within the Adobe Fill & Sign application on an iPhone.

- Product
- Adobe Fill & Sign
- Device & OS
- iOS (iPhone)
- Scenario
- Attempting to import a Microsoft Word document into the Adobe Fill & Sign mobile app to add an electronic signature or text.
- Observed behavior
- Microsoft Word DOCX files are unavailable and appear grayed out in the file browser when trying to import them into the Adobe Fill & Sign app.
Verify that your iPhone has an application installed capable of converting Word documents to PDF, such as WPS Office or the native Apple Files app, as direct Word imports are unsupported.
Convert the Word Document to PDF Before Importing
Since Adobe Fill & Sign does not support Microsoft Word files natively, you must convert the DOCX file into a PDF format before it can be recognized and opened by the application.
The Adobe Fill & Sign app is designed exclusively for processing PDF files and images. If you previously successfully filled out a Word document in this app, it is highly likely that the file was automatically or manually converted to a PDF first.
To resolve the grayed-out file issue, use a document management app or your device's built-in file tools to export the Word document as a PDF, then import that new PDF into Adobe Fill & Sign.
Locate the DOCX file on your iPhone using the 'Files' app or a compatible document reader like WPS Office.
Use the application's export or print feature to save the document as a PDF. In the native iOS Files app, you can often do this by tapping 'Share' and selecting 'Print', then using two fingers to zoom out on the preview to save it as a PDF.
Launch the Adobe Fill & Sign app, tap the '+' icon to add a new form, and select 'File Browser'.
Navigate to the location where you saved the converted PDF and tap on it. The file will no longer be grayed out and will open successfully for signing.

Convert and Sign Word Documents in One Place with WPS Office
Instead of switching between multiple apps to convert your Word document to PDF and then sign it, you can handle the entire process seamlessly using the WPS Office mobile app.
- 1. Open the DOCX file: Launch the WPS Office app on your iPhone and open your Microsoft Word document.
- 2. Convert to PDF: Tap the 'Tools' menu at the bottom, navigate to the 'File' tab, and select 'Export to PDF'.
- 3. Access PDF Editing Tools: Once the file is converted and opened as a PDF, tap on 'Tools' again and select 'PDF Edit' or the dedicated 'Fill & Sign' option.
- 4. Sign and Save: Insert your electronic signature, fill in any necessary text, and save the finalized PDF to your device.

Frequently Asked Questions
Why are my files grayed out in Adobe Fill & Sign on iPhone?
Files appear grayed out because they are in an unsupported format, such as Microsoft Word (DOCX) or Plain Text (TXT). Adobe Fill & Sign only recognizes and allows you to select PDF files or images.
Did Adobe Fill & Sign previously support Word documents?
No, Microsoft Word files have never been supported directly in Adobe Fill & Sign. If you used a Word document in the past, it was likely converted to a PDF by another app or email client before you opened it.
Can I electronically sign a Word document on my iPhone without converting it?
Standard electronic signature workflows generally require documents to be in PDF format to preserve formatting and secure the signature. You must convert the Word document to a PDF or image format first before applying a signature in most mobile apps.
