Python에서 PNG를 PDF 파일로 변환하는 방법

1.0 Introduction

IronPDF for Python library is a tool that you can use to streamline your experience when working with PDF files and converting image files into PDF files. It excels at extracting various types of data—such as images, radio buttons, and list box widgets—and transforming them into structured data that is simpler for programmers to understand.

2.0 IronPDF for Python

Programmers using Python can now easily handle the PDF format with the help of the IronPDF for Python library, which offers a comprehensive set of PDF functions. There are also more options for developing graphical user interfaces (GUI) thanks to its ability to integrate with other frameworks.

Due to Python's versatility and ease of use in creating graphical user interfaces, it is a programming language that many developers prefer. Because of its dynamic nature, it is distinct from other programming languages.

3.0 Convert PNG to PDF file

This section uses IronPDF for Python to convert an image to a PDF after installing IronPDF and creating the new PyCharm project folder. You can see how to convert one image to a PDF file extension in the following code example.

from ironpdf import ImageToPdfConverter

# Create a PDF from an image file named "Test.png"
pdf_converter = ImageToPdfConverter.ImageToPdf("Test.png")

# Save the converted PDF with the file name "Demo.pdf"
pdf_converter.SaveAs("Demo.pdf")

from ironpdf import ImageToPdfConverter

# Create a PDF from an image file named "Test.png"
pdf_converter = ImageToPdfConverter.ImageToPdf("Test.png")

# Save the converted PDF with the file name "Demo.pdf"
pdf_converter.SaveAs("Demo.pdf")

This bit of code creates a PDF from an image file called "Test.png" by using the IronPDF library to create an image-to-PDF converter. By using the path to the PNG image file as input, it first constructs an ImageToPdfConverter object. The object uses the ImageToPdf function and the original image file path to complete the conversion of the image to PDF.

Next, it uses the SaveAs function to save the converted PDF with the PDF file name "Demo.pdf". This will produce an output PDF with the same path as the Python script. In essence, it converts a PNG file to a PDF file, which is helpful for sharing and managing documents in many ways.

This also works with other file formats/file types, such as JPEG images. All you would need to do is change the code to include the suffix '.jpeg' or '.jpg' in the file path for the image, as shown in the code below.

from ironpdf import ImageToPdfConverter

# Create a PDF from an image file named "Test.jpeg"
pdf_converter = ImageToPdfConverter.ImageToPdf("Test.jpeg")

# Save the converted PDF with the file name "Demo.pdf"
pdf_converter.SaveAs("Demo.pdf")

from ironpdf import ImageToPdfConverter

# Create a PDF from an image file named "Test.jpeg"
pdf_converter = ImageToPdfConverter.ImageToPdf("Test.jpeg")

# Save the converted PDF with the file name "Demo.pdf"
pdf_converter.SaveAs("Demo.pdf")

The output PDF file

import os
from System.Collections.Generic import List
from ironpdf import ImageToPdfConverter

# Create a list of image file paths from the "assets" directory with ".png" extensions
image_files = [os.path.join("assets", f) for f in os.listdir("assets") if f.lower().endswith(".png")]

# Create a directory list to hold the image file paths
directory_list = List[str]()
for image_file in image_files:
    directory_list.Add(image_file)

# Convert the list of image files into a single PDF and save it as "Demo.pdf"
ImageToPdfConverter.ImageToPdf(directory_list).SaveAs("Demo.pdf")

import os
from System.Collections.Generic import List
from ironpdf import ImageToPdfConverter

# Create a list of image file paths from the "assets" directory with ".png" extensions
image_files = [os.path.join("assets", f) for f in os.listdir("assets") if f.lower().endswith(".png")]

# Create a directory list to hold the image file paths
directory_list = List[str]()
for image_file in image_files:
    directory_list.Add(image_file)

# Convert the list of image files into a single PDF and save it as "Demo.pdf"
ImageToPdfConverter.ImageToPdf(directory_list).SaveAs("Demo.pdf")
