Foreword:

When printing some PDF files, we may encounter encryption that cannot be printed, and you need to provide a password to print. If you browse PDF files directly in the browser, it cannot invoke the print function. But we can change a way of thinking to decrypt the file, you can print normally, the direction is as follows:

I'm going to print this today:

You actually need a password. Rubbish.

Then use Python to answer this password!

Get started.

1. convert individual PDF files import pikepdfwith pikepdf.open ("original print encrypted file.pdf") as pdf: num_pages = len(pdf.pages) del pdf.pages[-1] pdf.save ("New Unencrypted File.pdf")2. multifile conversion

We can put all the PDF files that need to be converted in one folder, put the results in another folder, and then run the following snippet code directly.

import pikepdfimport osinFile = input("Please input PDF data folder: ")outFile = input("Please input new PDF output folder: ")filelist = os.listdir(inFile)for file in filelist: if file.endswith(".pdf")and ("~$" not in file): filePath = inFile + "\\"+file print ("converting: ",filePath) with pikepdf.open(filePath) as pdf: num_pages = len(pdf.pages) del pdf.pages[-1] pdf.save(outFile + "\\"+ file)
