Quick Answer
Flattening bakes filled form fields into the page as permanent, printed-looking content. Run it after filling a form so nobody can edit the answers, so every viewer shows exactly what you see, and so scanners and copy machines do not resurrect empty boxes.

Frequently Asked Questions
What does flattening a PDF do?
Interactive PDFs store form answers as field objects layered on top of the page. Flattening replaces those layers with the rendered answer text directly on the page, then removes the fields. Visually nothing changes — but the values can no longer be edited, and viewers that ignore form fields finally show the answers.
When should I flatten a PDF?
After filling any form you plan to print, email, or archive: it locks the answers in, prevents accidental edits, and fixes viewers that show empty boxes. Also flatten before redacting or watermarking so those operations apply to the real, final content.
Will flattening keep my typed answers?
Yes — values are rendered into the page exactly as they appear. Checkbox ticks, radio choices, and dropdown selections are drawn as their appearance streams, so what you see is literally what gets baked in.
Is flattened text still searchable?
Flattened form values become page content, so yes — they respond to search and copy like normal PDF text. What disappears is editability: the values are no longer fields any tool can change.
