The second approach I tried is marking the widget read-only pdf_document = fitz.open("pdf", pdf_stream) READONLY_FLAG = 1 << 0 processed_fields = set() for index, page in enumerate(pdf_document): for field in page.widgets(): flag_image = False if not flag_image: if field.field_name not in processed_fields: print(f"non repeated name {field.field_name}, page {index}") processed_fields.add(field.field_name) field.field_flags |= READONLY_FLAG field.update() This works fine for most of the fields Except for fields that are repeated on multiple pages or on the same page.
