    image_path = Path(image_dir)

    extensions = ('.jpg', '.jpeg', '.png', '.webp')
    images = [f for f in image_path.iterdir() 
              if f.suffix.lower() in extensions]

    if order == 'name':
        images.sort()

    print(f"Combining {len(images)} images...")

    pdf_images = []
    for img_file in images:
        img = Image.open(img_file)

        if img.mode != 'RGB':
            img = img.convert('RGB')

        pdf_images.append(img)

    if pdf_images:
        pdf_images[0].save(
            output_pdf,
            save_all=True,
            append_images=pdf_images[1:]
        )

        print(f"✓ PDF created: {output_pdf}")

With Custom Page Size

from PIL import Image
from pathlib import Path

def images_to_pdf_a4(image_dir, output_pdf, page_size=(210, 297)):
    page_width, page_height = page_size
    dpi = 72
    px_width = int(page_width / 25.4 * dpi)
    px_height = int(page_height / 25.4 * dpi)

    image_path = Path(image_dir)
    images = [f for f in image_path.iterdir() if f.suffix.lower() in ('.jpg', '.png')]

    pdf_images = []
    for img_file in images:
        img = Image.open(img_file)

        img.thumbnail((px_width, px_height), Image.Resampling.LANCZOS)

        background = Image.new('RGB', (px_width, px_height), 'white')
        x = (px_width - img.width) // 2
        y = (px_height - img.height) // 2
        background.paste(img, (x, y))

        pdf_images.append(background)

    if pdf_images:
        pdf_images[0].save(output_pdf, save_all=True, append_images=pdf_images[1:])
