How to extract images from PDF in Python?

Last Updated : 09 Sep, 2024

The task in this article is to extract images from PDFs and convert them to Image to PDF and PDF to Image in Python.

To extract the images from PDF files and save them, we use the PyMuPDF library. First, we would have to install the PyMuPDF library using Pillow.

pip install PyMuPDF Pillow

PyMuPDF is used to access PDF files. To extract images from a PDF file, we need to follow the steps mentioned below-

Import necessary libraries
Specify the path of the file from which you want to extract images and open it
Iterate through all the pages of the PDF and get all images and objects present on every page
Use getImageList() method to get all image objects as a list of tuples
To get the image in bytes and along with the additional information about the image, use extractImage()

Implementation:

Python

# STEP 1 # import libraries import fitz  # PyMuPDF import io from PIL import Image  # STEP 2 # file path you want to extract images from file = "/content/pdf_file.pdf"  # open the file pdf_file = fitz.open(file)  # STEP 3 # iterate over PDF pages for page_index in range(len(pdf_file)):      # get the page itself     page = pdf_file.load_page(page_index)  # load the page     image_list = page.get_images(full=True)  # get images on the page      # printing number of images found in this page     if image_list:         print(f"[+] Found a total of {len(image_list)} images on page {page_index}")     else:         print("[!] No images found on page", page_index)          for image_index, img in enumerate(image_list, start=1):         # get the XREF of the image         xref = img[0]          # extract the image bytes         base_image = pdf_file.extract_image(xref)         image_bytes = base_image["image"]          # get the image extension         image_ext = base_image["ext"]          # save the image         image_name = f"image{page_index+1}_{image_index}.{image_ext}"         with open(image_name, "wb") as image_file:             image_file.write(image_bytes)             print(f"[+] Image saved as {image_name}")

Output:

Image to PDF and PDF to Image Conversion:

Image to PDF Conversion

Note: The image used here can be found here.

Python

import fitz doc = fitz.open() imgdoc = fitz.open('image.jpeg')  # open image pdfbytes = imgdoc.convert_to_pdf() imgpdf = fitz.open("pdf", pdfbytes) doc.insert_pdf(imgpdf) doc.save('imagetopdf.pdf')  # save file

First, we opened a blank document. Then we opened the image.

Now the image is converted to PDF using the convert_to_pdf() method.

After conversion, the image is appended to the empty doc which we created at starting. The document is saved after it has been appended.

Output:

PDF to Image Conversion

Note: We are using the sample.pdf for PDf to image conversion; to get the pdf, use the link below.

Python

import fitz doc = fitz.open('sample.pdf') for page in doc:     pix = page.get_pixmap(matrix=fitz.Identity, dpi=None,                           colorspace=fitz.csRGB, clip=None, alpha=True, annots=True)     pix.save("samplepdfimage-%i.jpg" % page.number)  # save file
