使用Python压缩PDF

import os
import PyPDF2
import pdfminer.layout
import pdfminer.pdfdocument
import zipfile

# 指定要压缩的PDF文件列表
pdf_files = ['file1.pdf', 'file2.pdf', 'file3.pdf']

# 将PDF文件压缩为一个ZIP文件
output_file = 'compressed_pdf.zip'

with zipfile.ZipFile(output_file, 'w', zipfile.ZIP_DEFLATED) as zf:
    for pdf_file in pdf_files:
        zf.write(pdf_file, os.path.basename(pdf_file))

with open(output_file, 'rb') as f:
    compressed_pdf = f.read()

# 使用PyPDF2库将压缩后的PDF文件还原为原始PDF文件
pdf_reader = PyPDF2.PdfFileReader(compressed_pdf)
pdf_writer = PyPDF2.PdfFileWriter()
for page_num in range(pdf_reader.numPages):
    page = pdf_reader.getPage(page_num)
    pdf_writer.addPage(page)

# 将还原后的PDF文件保存为一个新的PDF文件
with open('compressed_pdf_restored.pdf', 'wb') as f:
    pdf_writer.write(f)
