To Reproduce

PyMuPDF 1.23.25: Python bindings for the MuPDF 1.23.10 library (rebased implementation).

import fitz
class ModifyPDF:
    def __init__(self, input_path, outputFilePath):
        self.pdfFilePath = input_path
        self.outputFilePath = outputFilePath

    def remove_input_fields(self):
        docs = fitz.open(self.pdfFilePath)
        for page in docs:
            w = page.first_widget
            while w:
                w = page.delete_widget(w)

        docs.save(self.outputFilePath, garbage=3, deflate=True, pretty=True)
        docs.close()


if __name__ == "__main__":
    filePath = "example_form.pdf"
    outputPath = "output.pdf"
    PdfFunction = ModifyPDF(filePath, outputPath)
    PdfFunction.remove_input_fields()
