在 Python 中调整 pdf 页面的大小

pip install PyPDF2

import PyPDF2

def resize_pdf(input_path, output_path, width, height):
    with open(input_path, 'rb') as file:
        pdf = PyPDF2.PdfFileReader(file)
        writer = PyPDF2.PdfFileWriter()

        for page_num in range(pdf.getNumPages()):
            page = pdf.getPage(page_num)
            page.mediaBox.upperRight = (width, height)
            writer.addPage(page)

        with open(output_path, 'wb') as output_file:
            writer.write(output_file)

# 调整PDF页面大小为A4纸张大小
resize_pdf('input.pdf', 'output.pdf', 595, 842)
