How to Add Clickable URLs to an Adobe PDF Form Field
Question details
The user wants to allow respondents to enter clickable URLs into text fields within a PDF form, while ensuring long web addresses fit properly inside the field.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Creating or editing an interactive PDF form where users need to submit clickable website links.
- Observed behavior
- Users need a way to make entered text function as a hyperlink, but face formatting limitations because auto-fitting long URLs is disabled when rich text formatting is enabled.
Ensure you have Adobe Acrobat Pro or a compatible PDF editor with form creation capabilities installed, and that your PDF is open in form editing mode.
Enable Rich Text Formatting in PDF Form Fields
By enabling rich text formatting, form respondents can manually apply a hyperlink to their entered text using the Properties bar.
Rich text formatting allows users filling out the form to highlight text and add interactive hyperlinks. However, Adobe Acrobat disables the 'Auto' font size setting for rich text fields. This means you must assign a fixed font size, so clickable links and automatic text shrinking cannot be fully enabled at the same time.
Open your PDF in Adobe Acrobat, go to the 'Tools' menu, and select 'Prepare Form' to enter editing mode.
Right-click the specific text field where you want the user to enter a URL and select 'Properties' from the context menu.
Navigate to the 'Options' tab within the Text Field Properties dialog box and check the box next to 'Allow Rich Text Formatting'.
Switch to the 'Appearance' tab. Since 'Auto' sizing is no longer supported, select a fixed font size (e.g., 10 or 12) from the Font Size dropdown.
Close the properties window and save the form. Users can now press Ctrl+E (Windows) or Cmd+E (Mac) when selecting text in that field to open the Properties bar and add a link.

Frequently Asked Questions
Why isn't my PDF form field shrinking the text to fit the URL automatically?
If you have 'Allow Rich Text Formatting' enabled to support hyperlinks, Adobe Acrobat automatically disables the 'Auto' font size feature. You must choose one or the other: either automatic fitting without clickable links, or clickable links with a fixed font size.
Can a user simply paste a URL and have it become clickable automatically?
By default, plain text fields do not auto-convert text to active hyperlinks in most PDF viewers unless the viewer software itself automatically detects URLs. To guarantee a clickable link, the field must support rich text so the user can manually hyperlink it.
How does a user add a hyperlink in a rich text PDF field?
When filling the form, the user types the URL, highlights it, and presses Ctrl+E (Windows) or Cmd+E (Mac) to open the Text Properties toolbar. From there, they can format the highlighted text and insert the web address as an active hyperlink.
Are there other ways to handle long URLs in PDF forms?
As a workaround, you can increase the physical width of the text box or set it to 'Multi-line' in the Options tab so that long URLs wrap to the next line instead of being cut off.
