A practical guide

Review the flattened field appearance.

  1. Choose a PDF with supported fields and inspect the current values.
  2. Check all current values before making them page content.
  3. Create the copy and check that each value appears correctly on the page.

Try this example

Flatten a filled event form for a presentation copy. Inspect the finished pages to ensure the values remain aligned with their labels.

Before

  • Editable: A123

After

  • Page content: A123
Input and expected output for this task. Illustrative example.

Before you start: Flattening converts supported fields and current values into page content; it does not protect the PDF from editing. Other annotations remain unchanged.
