Flatten PDF Form
View key capabilities & tips
Flatten interactive form fields, annotations, and comments into the permanent visual content layer of a PDF. Lock form data to prevent accidental editing or tampering.
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.
