- Creating an interactive PDF form where respondents need to visually indicate locations on an embedded diagram.
- Observed behavior
- The form creator needs a non-destructive way for users to make marks on a diagram without altering the original background image.
Ensure you have a PDF editing software that supports the creation and customization of interactive form fields, such as checkboxes, radio buttons, or text fields.
Overlay Interactive Form Fields on the Diagram
Place transparent or clearly defined form fields over the diagram to allow users to click and mark areas seamlessly.
The most effective way to let users mark a diagram in a fillable PDF is by using interactive form fields like checkboxes, radio buttons, or clickable text fields. By placing these fields directly over the target areas of the diagram, users can simply click to place a mark without modifying the underlying image.
Open your PDF editor and insert the required diagram or illustration into the document background.
Navigate to the Form or Prepare Form tool in your PDF editor. Select the Checkbox, Radio Button, or Text Field tool.
Click and drag to draw the form fields over the specific areas of the diagram that users might need to mark.
Right-click the newly created form field, select Properties, and adjust the appearance. You can make the background and borders transparent so the diagram underneath remains fully visible.

Frequently Asked Questions
Can users draw freely on a fillable PDF form?
Standard fillable PDF form fields do not natively support freehand drawing. However, if the PDF permissions allow it, users can utilize the 'Comment' or 'Markup' tools to draw directly on the document.
How do I make the interactive form fields invisible until clicked?
In your PDF editor's form field properties, set the background color and border color to 'Transparent'. The field will remain invisible to the user until they click it to add a mark (like a checkmark or cross).
What is the best form field type for marking locations?
Checkboxes are typically the best choice for marking locations on a diagram because they are easy to click and clearly indicate a selection. Text fields can also be used if users need to type a specific number or letter over an area.
