Split every page in a pdf i a different pdf

This code will get as output as many pdf of 1 page as many pages are in the input pdf

from PyPDF2 import PdfFileWriter, PdfFileReader


# change the filetosplit.pdf name with the one you wanto to split
inputpdf = PdfFileReader("filetosplit.pdf", "rb")
print(inputpdf)
for i in range(inputpdf.numPages):
    output = PdfFileWriter()
    output.addPage(inputpdf.getPage(i))
    with open("document-page%s.pdf" % i, "wb") as outputStream:
        output.write(outputStream)

A graphic user interface

In this code we add a GUI to select the pdf we want to split

import tkinter as tk
from PyPDF2 import PdfFileWriter, PdfFileReader
import glob


def split(file):
    inputpdf = PdfFileReader(file, "rb")
    print(inputpdf)
    for i in range(inputpdf.numPages):
        output = PdfFileWriter()
        output.addPage(inputpdf.getPage(i))
        with open("document-page%s.pdf" % i, "wb") as outputStream:
            output.write(outputStream)
    lb.delete(0, tk.END)
    print(glob.glob("*.pdf"))
    for file in glob.glob("*.pdf"):
        lb.insert(tk.END, file)


root = tk.Tk()
root.geometry("400x400")
lb = tk.Listbox(root)
lb.pack()
for file in glob.glob("*.pdf"):
    lb.insert(tk.END, file)
lb.bind("<Double-Button>", lambda x: split(lb.get(lb.curselection()[0])))

root.mainloop()

Adding more features

Now you get more features. You have the chance to delete the splitted pages and to open them from the gui directly.

import tkinter as tk
import tkinter.ttk as ttk
from PyPDF2 import PdfFileWriter, PdfFileReader
import glob
import os
from tkinter import messagebox


def split(file):
    inputpdf = PdfFileReader(file, "rb")
    print(inputpdf)
    for i in range(inputpdf.numPages):
        output = PdfFileWriter()
        output.addPage(inputpdf.getPage(i))
        with open("output/document-page%s.pdf" % i, "wb") as outputStream:
            output.write(outputStream)
    lb.delete(0, tk.END)
    print(glob.glob("*.pdf"))
    refreshlist(lb2)


def refreshlist(lst):
    if lst == lb:
        folder = "input"
    elif lst == lb2:
        folder = "output"
        lst.delete(0, tk.END)
    for file in glob.glob(folder + "/*.pdf"):
        lst.insert(tk.END, file)
