Converting pdf to png with python (without pdf2image)

I want to convert a pdf (one page) into a png file. I installed pdf2image and get this error: popler is not installed in windows.

According to this question: Poppler in path for pdf2image, poppler should be installed and PATH modified.

I cannot do any of those (I don't have the necessary permissions in the system I am working with).

I had a look at opencv and PIL and none seems to offer the possibility to make this transformation: PIL (see here https://pillow.readthedocs.io/en/stable/handbook/image-file-formats.html?highlight=pdf#pdf) does not offer the possibility to read pdfs, only to save images as pdfs. The same goes for openCV.

Any suggestion how to make the pdf to png transformation ? I can install any python library but I can not touch the windows installation.

thanks

import fitz

input_pdf = r"Samples\104295.pdf"

output_jpg = r"Output\104295.jpg"

#The code splits the first page of pdf and converts to jpeg
def split_and_convert(pdf_path, output_path):
    doc = fitz.open(pdf_path)
    page = doc.load_page(0)
    pix = page.get_pixmap()
    pix.save(output_path, "jpeg")
    doc.close()

split_and_convert(input_pdf, output_jpg)

PyMuPDF supports pdf to image rasterization without requiring any external dependencies.

Sample code to do a basic pdf to png transformation:

import fitz  # PyMuPDF, imported as fitz for backward compatibility reasons
file_path = "my_file.pdf"
doc = fitz.open(file_path)  # open document
for i, page in enumerate(doc):
    pix = page.get_pixmap()  # render page to an image
    pix.save(f"page_{i}.png")

Here is a snippet that generates PNG images of arbitrary resolution (dpi):

import fitz
file_path = "my_file.pdf"
dpi = 300  # choose desired dpi here
zoom = dpi / 72  # zoom factor, standard: 72 dpi
magnify = fitz.Matrix(zoom, zoom)  # magnifies in x, resp. y direction
doc = fitz.open(fname)  # open document
for page in doc:
    pix = page.get_pixmap(matrix=magnify)  # render page to an image
    pix.save(f"page-{page.number}.png")

Generates PNG files name page-0.png, page-1.png, ... By choosing dpi < 72 thumbnail page images would be created.
