I’m trying to make a Image converter to PDF in Python. It works well when selecting just one image, but when I select multiple ones, it gives me this error: ‘str’ obejct has no attribute ‘encoderinfo’.

Here’s my full code:

import tkinter as tk
from tkinter import filedialog
from tkinter import messagebox
from PIL import Image
import os
# function to convert images to PDF
def images_to_pdf(images, pdf_name):
    try:
        # create a new pdf file
        pdf = Image.open(images[0])
        pdf.save(pdf_name, "PDF", resolution=100.0,
                 save_all=True, append_images=images[1:])
        messagebox.showinfo("Success",
            "Images have been successfully converted to PDF.")
    except Exception as e:
        messagebox.showerror("Error",
            "Failed to convert images to PDF.nError: " + str(e))
# function to select images
def select_images():
    images = filedialog.askopenfilenames(title="Select Images",
        filetypes=(("Image files", "*.jpg;*.jpeg;*.png"),
    ("All files", "*.*")), initialdir = "C:/")
    return images
# function to select pdf name and path
def select_pdf():
    pdf = filedialog.asksaveasfilename(title="Save PDF As",
        defaultextension=".pdf", initialdir = "C:/",
    filetypes=(("PDF files", "*.pdf"),("All files", "*.*")))
    return pdf
# create GUI
root = tk.Tk()
root.title("Convert Images to PDF")
select_images_btn = tk.Button(root,
    text="Select Images", command=select_images)
select_pdf_btn = tk.Button(root, text="Select PDF",
                           command=select_pdf)
convert_btn = tk.Button(root, text="Convert",
    command=lambda: images_to_pdf(select_images(), select_pdf()))
select_images_btn.pack()
select_pdf_btn.pack()
convert_btn.pack()
root.mainloop()

How am I able to select multiples images and put it in just one whole PDF file?
