Flatten interactive AcroForm fields into page content in a new PDF copy. Other annotations are not flattened.
Free to use. No account required.
This tool targets interactive PDF form fields only. It does not flatten comments, highlights, stamps, or other annotations.
Choose one PDF file to begin. The original will not be changed.
Flatten PDF converts supported interactive AcroForm fields, such as text inputs and checkboxes, into page content in a separate copy. The field values remain visible, but the fields are no longer editable as form controls.
Flattening does not remove or flatten every annotation type. It is not a security redaction method: hidden or covered information may remain in the file. Check the output with the viewer and workflow you intend to use.
Open the document in a PDF reader and try a field that is meant to accept an answer. A box printed on a scanned or static form is page artwork, not an interactive form control. This tool needs interactive AcroForm fields; if none are found, it stops without creating a download. Keep an editable original if you may need to revise the answers later.
Flattening is useful after you finish an interactive form when the next person needs to read the entered values without using those fields as controls. Keep the original if answers may need changes later, because the flattened values no longer behave as form fields. This operation does not password-protect the PDF or make the rest of its page content read-only. It is not a way to remove confidential information.
PDFs without interactive form fields are not processed. Encrypted, malformed, or unsupported documents may fail. Editing may invalidate a digital signature.
No. This tool flattens AcroForm fields only; other annotation types are outside its scope.
No. It is not a redaction or sanitization method.
