Fix Word ActiveX Controls Not Interactive After PDF Conversion
Question details
Users are unable to interact with ActiveX form controls, such as radio buttons and checkboxes, after converting a Microsoft Word document into a PDF file.

- Product
- Word to PDF
- Device & OS
- not provided
- Scenario
- Converting a Microsoft Word document containing interactive ActiveX form controls into a fillable PDF form.
- Observed behavior
- While standard text fields may occasionally convert properly, ActiveX radio buttons and checkboxes lose their interactivity and are flattened into static, unclickable visual elements in the final PDF.
Before proceeding, ensure you have access to a dedicated PDF editor, as standard Word-to-PDF conversion engines cannot natively translate ActiveX controls into functional PDF form fields.
Recreate Form Fields Using a Dedicated PDF Editor
Since ActiveX controls do not convert automatically, the most reliable method is to convert the document to a static PDF and manually recreate the interactive fields directly within a PDF editing tool.
Microsoft's proprietary ActiveX controls are not reliably supported by PDF conversion standards. To achieve a fully functional fillable PDF, you must use the form building tools provided by advanced PDF software.
Open your document in Microsoft Word and save it as a standard PDF file by going to File > Save As and choosing PDF.
Launch a professional PDF editor (such as Adobe Acrobat or WPS PDF) and open your newly saved static PDF.
Navigate to the 'Form' or 'Prepare Form' tab on the main toolbar to reveal the interactive field options.
Select the appropriate form tools (Check Box, Radio Button, Text Field) and click and drag to place them exactly over the static visual elements from your Word document.
Once all fields are placed and configured, save the PDF. Test the form by clicking the fields to ensure they behave correctly.

Switch to HTML Forms for Better Cross-Platform Compatibility
If your users experience issues with fillable PDFs across different devices and browsers, consider rebuilding the form as an HTML webpage.
Create Interactive PDF Forms with WPS Office
Bypass Word's ActiveX conversion limitations by using WPS PDF. Easily convert your documents and add highly functional interactive form fields like checkboxes, text boxes, and radio buttons using built-in form tools.
- 1. Export Word to PDF: Open your original document in WPS Writer and export it as a standard PDF file.
- 2. Open with WPS PDF: Launch the newly created PDF file using the built-in WPS PDF application.
- 3. Navigate to Form Tools: Click on the 'Form' tab located on the top navigation ribbon to access interactive elements.
- 4. Insert Form Controls: Select the desired form controls, such as Check Box or Radio Button, and drag them onto your document layout.
- 5. Save the Document: Save your newly created interactive PDF form to share with your users.

Frequently Asked Questions
Why do my Word ActiveX checkboxes disappear or stop working when saved as PDF?
Standard PDF conversion engines do not support the translation of Microsoft's proprietary ActiveX controls into interactive PDF form fields. Consequently, these elements are rendered as flat, unclickable images or text.
Can I convert Word legacy form fields to a fillable PDF automatically?
While some premium PDF creators can detect and convert basic legacy text fields into PDF fields automatically, complex elements like checkboxes, radio buttons, and dropdowns typically require manual recreation using a dedicated PDF editor.
Are fillable PDF forms compatible with mobile devices?
PDF form compatibility varies widely on mobile devices. Built-in system viewers on iOS and Android often struggle with interactive fields and scripts. For the most reliable experience, users should open the form using a dedicated PDF application like WPS Office.
