What this tool preserves

Supports AcroForms, not XFA. Does not flatten all annotations or prevent editing.

Privacy and practical limits

Files stay on your device. Each input must be under 150 MB. Processing speed and memory use depend on your device. Keep original documents; PDF transformations do not preserve digital-signature validity.

Does flattening make a PDF impossible to edit?

No. It converts fillable form fields into page content. A PDF editor can still modify that content. This is not password protection.

Does this flatten all annotations?

No. It flattens standard AcroForm fields, using their saved appearances. Other annotations and XFA forms are outside this tool’s scope.

Will filled-in values remain visible?

Saved field appearances are placed on the page. Open the result to check them. If the form has missing appearances, save it in a PDF form editor before flattening.
