Question details
The user wants to customize the text that appears when hovering over an image hyperlink in a PDF document without modifying the underlying destination URL.
- Product
- PDF Editor
- Device & OS
- not provided
- Scenario
- Adding custom hover text to image hyperlinks in a PDF document to improve clarity or context without breaking the original URL destination.
- Observed behavior
- Standard PDF hyperlinks typically display the destination URL or do not allow for a separate, custom hover text distinct from the URL itself.
Ensure you are using a PDF editing application capable of creating and modifying interactive form fields, specifically button fields, as standard link insertion tools do not usually support custom tooltips.
Use a Button Field to Set Custom Tooltips
Replace standard hyperlinks with an invisible button field. This allows you to set a custom tooltip for the hover text while independently configuring the click action to open your desired URL.
Standard PDF links are limited in their tooltip customization. By overlaying an interactive button field on top of your image, you can completely control the hover behavior and the resulting action when clicked.
Open your PDF editor, navigate to the Form or Interactive elements tab, and select the 'Button' tool. Draw a rectangle over the target image.
Right-click the newly created button field and select 'Properties'. Under the General tab, find the 'Tooltip' field and enter the exact hover text you want users to see.
Switch to the Actions tab in the button properties. Set the 'Select Trigger' to 'Mouse Up' and the 'Select Action' to 'Open a web link'. Click 'Add' and input your destination URL.
Navigate to the Appearance tab. Set both the border color and fill color to transparent or 'No Color' so the underlying image remains fully visible when viewing the document.
Edit PDF Links and Tooltips with WPS Office
WPS PDF provides robust form editing tools, allowing you to easily insert buttons over images, customize hover text (tooltips), and set URL actions without hassle.
- 1. Open the PDF in WPS: Launch WPS Office and open your PDF document using the built-in WPS PDF tool.
- 2. Access the Form Tools: Navigate to the 'Form' tab on the top ribbon and select 'Push Button' to draw a button overlay exactly over your image.
- 3. Customize the Tooltip: Double-click the button to open the Properties dialog. In the 'General' tab, type your desired custom hover text into the 'Tooltip' text box.
- 4. Set the Link Action: Switch to the 'Actions' tab, choose 'Open a web link' from the action dropdown menu, and input your target URL.
- 5. Adjust Appearance and Save: In the 'Appearance' tab, set the border and background colors to transparent so the image underneath shows clearly, then save your PDF document.
Frequently Asked Questions
Why does a standard PDF link show the URL instead of custom text?
Standard hyperlink objects in PDFs typically default to displaying the destination URL as the hover text. Modifying this requires replacing the basic link with an interactive form element, like a button, that inherently supports custom tooltips.
Will the invisible button print out over the image on the PDF?
No, if you set the button's appearance to have no border and no fill color, it remains invisible both on-screen and when printed. You can also explicitly set the button property under the General tab to 'Visible but doesn't print'.
Does custom hover text work on mobile PDF readers?
Hover functionality (tooltips) generally relies on a mouse cursor. Mobile devices use touch screens, so tooltips might not display when tapping or pressing an image on a smartphone or tablet, although the link will still work.
