Extract a page from a pdf as a jpeg

Question

In python code, how to efficiently save a certain page in a pdf as a jpeg file? (Use case: I've a python flask web server where pdf-s will be uploaded and jpeg-s corresponding to each page is stores.)

This solution is close, but the problem is that it does not convert the entire page to jpeg.

Answer 1

The pdf2image library can be used.

You can install it simply using,

pip install pdf2image

Once installed you can use following code to get images.

from pdf2image import convert_from_path
pages = convert_from_path('pdf_file', 500)

Saving pages in jpeg format

for page in pages:
    page.save('out.jpg', 'JPEG')

---

Edit: the Github repo pdf2image also mentions that it uses pdftoppm and that it requires other installations:

pdftoppm is the piece of software that does the actual magic. It is distributed as part of a greater package called poppler. Windows users will have to install poppler for Windows. Mac users will have to install poppler for Mac. Linux users will have pdftoppm pre-installed with the distro (Tested on Ubuntu and Archlinux) if it's not, run sudo apt install poppler-utils.

You can install the latest version under Windows using anaconda by doing:

conda install -c conda-forge poppler

note: Windows versions upto 0.67 are available at http://blog.alivate.com.au/poppler-windows/ but note that 0.68 was released in Aug 2018 so you'll not be getting the latest features or bug fixes.

Answer 2

I found this simple solution, PyMuPDF, output to png file. Note the library is imported as "fitz", a historical name for the rendering engine it uses.

import fitz

pdffile = "infile.pdf"
doc = fitz.open(pdffile)
page = doc.loadPage(0)  # number of page
pix = page.get_pixmap()
output = "outfile.png"
pix.save(output)

Answer 3

The Python library pdf2image (used in the other answer) in fact doesn't do much more than just launching pdttoppm with subprocess.Popen, so here is a short version doing it directly:

PDFTOPPMPATH = r"D:\Documents\software\____PORTABLE\poppler-0.51\bin\pdftoppm.exe"
PDFFILE = "SKM_28718052212190.pdf"

import subprocess
subprocess.Popen('"%s" -png "%s" out' % (PDFTOPPMPATH, PDFFILE))

Here is the Windows installation link for pdftoppm (contained in a package named poppler): http://blog.alivate.com.au/poppler-windows/.

Answer 4

There is no need to install Poppler on your OS. This will work:

pip install Wand

from wand.image import Image

f = "somefile.pdf"
with(Image(filename=f, resolution=120)) as source: 
    for i, image in enumerate(source.sequence):
        newfilename = f[:-4] + str(i + 1) + '.jpeg'
        Image(image).save(filename=newfilename)

Answer 5

@gaurwraith, install poppler for Windows and use pdftoppm.exe as follows:

1. Download zip file with Poppler's latest binaries/dlls from http://blog.alivate.com.au/poppler-windows/ and unzip to a new folder in your program files folder. For example: "C:\Program Files (x86)\Poppler".

2. Add "C:\Program Files (x86)\Poppler\poppler-0.68.0\bin" to your SYSTEM PATH environment variable.

3. From cmd line install pdf2image module -> "pip install pdf2image".

4. Or alternatively, directly execute pdftoppm.exe from your code using Python's subprocess module as explained by user Basj.

@vishvAs vAsuki, this code should generate the jpgs you want through the subprocess module for all pages of one or more pdfs in a given folder:

import os, subprocess

pdf_dir = r"C:\yourPDFfolder"
os.chdir(pdf_dir)

pdftoppm_path = r"C:\Program Files (x86)\Poppler\poppler-0.68.0\bin\pdftoppm.exe"

for pdf_file in os.listdir(pdf_dir):

    if pdf_file.endswith(".pdf"):

        subprocess.Popen('"%s" -jpeg %s out' % (pdftoppm_path, pdf_file))

Or using the pdf2image module:

import os
from pdf2image import convert_from_path

pdf_dir = r"C:\yourPDFfolder"
os.chdir(pdf_dir)

    for pdf_file in os.listdir(pdf_dir):

        if pdf_file.endswith(".pdf"):

            pages = convert_from_path(pdf_file, 300)
            pdf_file = pdf_file[:-4]

            for page in pages:

               page.save("%s-page%d.jpg" % (pdf_file,pages.index(page)), "JPEG")

Answer 6

Using pypdfium2:

python3 -m pip install pypdfium2

import pypdfium2 as pdfium

pdffile = 'path/to/your_doc.pdf'

# render multiple pages concurrently (in this case: all)
for image, suffix in pdfium.render_pdf_topil(pdffile):
    image.save('output_%s.jpg' % suffix)

# render a single page (in this case: the first one)
with pdfium.PdfContext(pdffile) as pdf:
    image = pdfium.render_page_topil(pdf, 0)
    image.save('output.jpg')

Advantages:

• PDFium is liberal-licensed (BSD 3-Clause or Apache 2.0, at your choice)
• It is fast, outperforming Poppler. In terms of speed, pypdfium2 can almost reach PyMuPDF
• Returns PIL.Image.Image, bytes, or a ctypes array, depending on your needs
• Is capable of processing encrypted (password-protected) PDFs
• No runtime dependencies except PIL, which is optional
• Supports Python >= 3.5
• Setup infrastructure complies with PEP 517/518, while legacy setup still works as well

Wheels are currently available for

• Windows amd64, win32, arm64
• macOS x86_64, arm64
• Linux (glibc) x86_64, i686, aarch64, armv7l
• Linux (musl) x86_64, i686

There is a script to build from source, too.

Answer 7

GhostScript performs much faster than Poppler for a Linux based system.

Following is the code for pdf to image conversion.

def get_image_page(pdf_file, out_file, page_num):
    page = str(page_num + 1)
    command = ["gs", "-q", "-dNOPAUSE", "-dBATCH", "-sDEVICE=png16m", "-r" + str(RESOLUTION), "-dPDFFitPage",
               "-sOutputFile=" + out_file, "-dFirstPage=" + page, "-dLastPage=" + page,
               pdf_file]
    f_null = open(os.devnull, 'w')
    subprocess.call(command, stdout=f_null, stderr=subprocess.STDOUT)

GhostScript can be installed on macOS using brew install ghostscript

Installation information for other platforms can be found here. If it is not already installed on your system.

Answer 8

Their is a utility called pdftojpg which can be used to convert the pdf to img

You can found the code here https://github.com/pankajr141/pdf2jpg

from pdf2jpg import pdf2jpg
inputpath = r"D:\inputdir\pdf1.pdf"
outputpath = r"D:\outputdir"
# To convert single page
result = pdf2jpg.convert_pdf2jpg(inputpath, outputpath, pages="1")
print(result)

# To convert multiple pages
result = pdf2jpg.convert_pdf2jpg(inputpath, outputpath, pages="1,0,3")
print(result)

# to convert all pages
result = pdf2jpg.convert_pdf2jpg(inputpath, outputpath, pages="ALL")
print(result)

Answer 9

One problem,everyone will face that is to Install Poppler.My way is a tricky way,but will work efficiently.1st download Poppler here.Then Extract it add In the code section just add poppler_path=r'C:\Program Files\poppler-0.68.0\bin'(for eg.) like below

from pdf2image import convert_from_path
images = convert_from_path("mypdf.pdf", 500,poppler_path=r'C:\Program Files\poppler-0.68.0\bin')
for i, image in enumerate(images):
    fname = 'image'+str(i)+'.png'
    image.save(fname, "PNG")

Answer 10

Here is a function that does the conversion of a PDF file with one or multiple pages to a single merged JPEG image.

import os
import tempfile
from pdf2image import convert_from_path
from PIL import Image

def convert_pdf_to_image(file_path, output_path):
    # save temp image files in temp dir, delete them after we are finished
    with tempfile.TemporaryDirectory() as temp_dir:
        # convert pdf to multiple image
        images = convert_from_path(file_path, output_folder=temp_dir)
        # save images to temporary directory
        temp_images = []
        for i in range(len(images)):
            image_path = f'{temp_dir}/{i}.jpg'
            images[i].save(image_path, 'JPEG')
            temp_images.append(image_path)
        # read images into pillow.Image
        imgs = list(map(Image.open, temp_images))
    # find minimum width of images
    min_img_width = min(i.width for i in imgs)
    # find total height of all images
    total_height = 0
    for i, img in enumerate(imgs):
        total_height += imgs[i].height
    # create new image object with width and total height
    merged_image = Image.new(imgs[0].mode, (min_img_width, total_height))
    # paste images together one by one
    y = 0
    for img in imgs:
        merged_image.paste(img, (0, y))
        y += img.height
    # save merged image
    merged_image.save(output_path)
    return output_path

Example usage: -

convert_pdf_to_image("path_to_Pdf/1.pdf", "output_path/output.jpeg")

Answer 11

I wrote this script to easily convert a folder directory that contains PDFs (single page) to PNGs really nicely.

import os
from pathlib import PurePath
import glob
# from PIL import Image
from pdf2image import convert_from_path
import pdb

# In[file list]

wd = os.getcwd()

# filter images
fileListpdf = glob.glob(f'{wd}//*.pdf')

# In[Convert pdf to images]

for i in fileListpdf:
    
    images = convert_from_path(i, dpi=300)
    
    path_split = PurePath(i).parts
    fileName, ext = os.path.splitext(path_split[-1])
    
    images[0].save(f'{fileName}.png', 'PNG')

Hopefully, this helps if you need to convert PDFs to PNGs!

Answer 12

I use a (maybe) much simpler option of pdf2image:

cd $dir
for f in *.pdf
do
  if [ -f "${f}" ]; then
    n=$(echo "$f" | cut -f1 -d'.')
    pdftoppm -scale-to 1440 -png $f $conv/$n
    rm $f
    mv  $conv/*.png $dir
  fi
done

This is a small part of a bash script in a loop for the use of a narrow casting device. Checks every 5 seconds on added pdf files (all) and processes them. This is for a demo device, at the end converting will be done at a remote server. Converting to .PNG now, but .JPG is possible too.

This converting, together with transitions on A4 format, displaying a video, two smooth scrolling texts and a logo (with transition in three versions) sets the Pi3 to allmost 4x 100% cpu-load ;-)

Answer 13

from pdf2image import convert_from_path
import glob

pdf_dir = glob.glob(r'G:\personal\pdf\*')  #your pdf folder path
img_dir = "G:\\personal\\img\\"           #your dest img path

for pdf_ in pdf_dir:
    pages = convert_from_path(pdf_, 500)
    for page in pages:
        page.save(img_dir+pdf_.split("\\")[-1][:-3]+"jpg", 'JPEG')

Answer 14

Here is a solution which requires no additional libraries and is very fast. This was found from: https://nedbatchelder.com/blog/200712/extracting_jpgs_from_pdfs.html# I have added the code in a function to make it more convenient.

def convert(filepath):
    with open(filepath, "rb") as file:
        pdf = file.read()

    startmark = b"\xff\xd8"
    startfix = 0
    endmark = b"\xff\xd9"
    endfix = 2
    i = 0

    njpg = 0
    while True:
        istream = pdf.find(b"stream", i)
        if istream < 0:
            break
        istart = pdf.find(startmark, istream, istream + 20)
        if istart < 0:
            i = istream + 20
            continue
        iend = pdf.find(b"endstream", istart)
        if iend < 0:
            raise Exception("Didn't find end of stream!")
        iend = pdf.find(endmark, iend - 20)
        if iend < 0:
            raise Exception("Didn't find end of JPG!")

        istart += startfix
        iend += endfix
        jpg = pdf[istart:iend]
        newfile = "{}jpg".format(filepath[:-3])
        with open(newfile, "wb") as jpgfile:
            jpgfile.write(jpg)

        njpg += 1
        i = iend

        return newfile

Call convert with the pdf path as the argument and the function will create a .jpg file in the same directory

Answer 15

For a pdf file with multiple pages, the following is the best & simplest (I used pdf2image-1.14.0):

from pdf2image import convert_from_path
from pdf2image.exceptions import (
     PDFInfoNotInstalledError,
     PDFPageCountError,
     PDFSyntaxError
     )
        
images = convert_from_path(r"path/to/input/pdf/file", output_folder=r"path/to/output/folder", fmt="jpg",) #dpi=200, grayscale=True, size=(300,400), first_page=0, last_page=3)
        
images.clear()

Note:

1. "images" is a list of PIL images.
2. The saved images in the output folder will have system generated names; one can later change them, if required.

Answer 16

This easy script can convert a folder directory that contains PDFs (single/multiple pages) to jpeg.

from PIL import Image

    try:
        shutil.move(doc_path + '/' + file, download_processed + '/' + file)
        pass
    except Exception as e:
        print(e.errno)
        raise
    else:
        pass
    finally:
        pass
    pass

    files = [f for f in listdir(doc_path) if isfile(join(doc_path, f))]

    pdf_files = [f for f in listdir(doc_path) if isfile(join(doc_path, f)) and f.lower().endswith('.pdf')]

    # check OS type
    if os.name == 'nt':
        # if is windows or a graphical OS, change this poppler path with your own path
        poppler_path = r"C:\poppler-0.68.0\bin"
    else:
        poppler_path = root_dir + r"\usr\bin"

    for file in pdf_files:

        pages = convert_from_path(doc_path + '/' + file, 500, poppler_path=poppler_path)

        # Counter to store images of each page of PDF to image
        image_counter = 1

        filename, file_extension = os.path.splitext(file)

        # Iterate through all the pages stored above
        for page in pages:
            # Declaring filename for each page of PDF as JPG
            # PDF page n -> page_n.jpg
            filename = filename + '_' + str(image_counter) + ".jpg"

            # Save the image of the page in system
            page.save(results_folder + '/' + filename, 'JPEG')

            # Increment the counter to update filename
            image_counter += 1
