A practical guide

Fill the fields already in the form.

  1. Choose a PDF with supported existing fields and inspect the field list.
  2. Enter text or choose available checkbox, dropdown or radio values.
  3. Choose whether to flatten the fields, create the copy, then inspect each value.

Try this example

Enter a name in an existing contact form field and check the saved appearance. Use the original to verify spelling before sharing the filled copy.

Before

  • Reference: empty

After

Input and expected output for this task. Illustrative example.

Before you start: This fills supported existing fields; it does not create fields. XFA, signature fields and scripts are unsupported, and field appearances may change. Flatten only when a fixed visual copy is intended.
