View key capabilities & tips
Key capabilities:
  • Converts interactive form elements into non-editable standard page graphics
  • Renders text field entries, checkboxes, and stamps directly into the page stream
  • Preserves visual typography, line weights, and layout clarity
  • Client-side execution keeps document data securely in browser memory
Tips:
  • Always verify all form entries are correct before flattening, as fields cannot be reopened afterward.
  • Keep a copy of the unflattened form in case you need to revise field values later.
  • Open the flattened output in a browser or PDF reader to confirm form boxes are no longer editable.
