Question details
The user needs to know how to make PDF form fields and required-field indicators visible for Windows users.

- Product
- PDF Reader
- Device & OS
- Windows / macOS
- Scenario
- Viewing an interactive PDF form created on a Mac on a Windows PC.
- Observed behavior
- Form fields and required-field indicators are highlighted and visible on Mac computers, but do not appear highlighted for users on Windows PCs.
Ensure you have a standard PDF reader installed on your Windows PC and that the PDF document contains interactive form fields rather than just flat text.
Enable Field Highlighting in Windows PDF Reader Preferences
Field highlighting is a local application setting rather than a document or OS property. You must enable it in your PDF reader's preferences on Windows.
The visibility of form fields is controlled by each individual user's PDF reader preferences, not by the operating system or the original creator's device.
Launch your PDF reader on your Windows PC. Click on the 'Edit' menu at the top of the screen and select 'Preferences'.
In the Preferences dialog box, locate and click on 'Forms' in the left-hand Categories pane.
Ensure the field highlighting option is turned on. You can also customize the highlight color for standard fields and required fields here. Click 'OK' to save your changes.

Use WPS Office to Fill and Edit PDF Forms
WPS PDF provides a seamless experience for viewing, filling, and editing interactive PDF forms. Form fields are automatically recognized and highlighted by default, ensuring you never miss a required input.
- 1. Open the PDF in WPS Office: Launch WPS Office, click on 'Open', and select your interactive PDF form.
- 2. Access Form Tools: Navigate to the 'Form' tab on the top ribbon to view all available form editing and filling options.
- 3. Highlight Fields: Click on the 'Highlight Fields' button in the toolbar to instantly make all fillable areas visible.
- 4. Fill and Save: Click into the highlighted fields to type your information, then go to 'Menu' and select 'Save' to keep your changes.

Frequently Asked Questions
Why do PDF form fields show up on Mac but not on Windows?
The visibility of form fields depends on the default settings of the PDF reader installed on the device, not the operating system itself. The reader on the Mac likely had field highlighting enabled by default, while the Windows PDF reader did not.
Can I force form fields to be highlighted for everyone who opens my PDF?
No, field highlighting is controlled by the individual user's application preferences. However, you can add visual cues like colored boxes or borders to the form fields during the creation process so they are visible regardless of the user's settings.
How do I change the highlight color of PDF form fields?
In Adobe Acrobat, go to Edit > Preferences > Forms (or Acrobat > Preferences > Forms on a Mac). Under the Highlight Color section, you can choose custom colors for standard fields and required fields.
Are interactive PDF forms compatible across different PDF readers?
Yes, standard interactive PDF forms are generally compatible across major PDF readers like WPS PDF, Adobe Acrobat, and Foxit. However, the way they are visually displayed (like highlighting) may vary depending on the software's settings.
