Drop in your PDF

Flatten
Fields and their values are drawn permanently into the page.
Download the flat PDF
Same look, no editable fields — safe to archive or send.
Flattening turns interactive form fields — text boxes, checkboxes, dropdowns — into fixed page content. The values people typed stay visible but can no longer be edited, which is exactly what you want before archiving or sending a final version.
The tool reports how many fields were flattened so you can confirm it did something. Flattening is one-way: keep the original if you might need the editable form later. Note that it flattens form fields; annotations and layered artwork are handled by the full app’s flatten options.
Questions, answered
It converts interactive form fields into static page content — visible, but no longer editable.
