How to Convert XPS to JPG Using Python

Working with file conversions can sometimes feel tricky, but Python makes it easier with its powerful libraries. In this article, I’ll explain how to convert an XPS file (XML Paper Specification) to JPG images using the PyMuPDF module, also known as fitz. Don’t worry if you are a beginner; I will guide you step by step.

What is PyMuPDF?

PyMuPDF is a Python library used to work with PDF and other document formats, including XPS. It allows you to extract pages, images, and text and save pages as images. For this task, we’ll use it to read an XPS file and save its pages as JPG files.

Steps to Convert XPS to JPG

Let’s break this down into simple steps:

1. Install PyMuPDF

Before we start, you need to have PyMuPDF installed. Open your terminal or command prompt and type:

pip install pymupdf

2. Open the XPS File

First, we need to load the XPS file into our Python program. PyMuPDF makes this easy with its fitz.open() function.

3. Loop Through Pages

XPS files are divided into pages. You need to go through each page, one by one, and convert it to an image.

4. Save Pages as JPG

Finally, you can save each page as a JPG file. PyMuPDF provides a method called get_pixmap() that renders a page as an image. You can then save it as a JPG file using the save() method.

Full Python Code

import fitz # PyMuPDF library

# Step 1: Specify the path to your XPS file
xps_file = "example.xps" # Replace with your XPS file name

# Step 2: Open the XPS file
doc = fitz.open(xps_file)

# Step 3: Loop through each page in the file
for page_num in range(len(doc)):
 # Get the page
 page = doc.load_page(page_num)
 
 # Render the page as an image (pixmap)
 pix = page.get_pixmap()
 
 # Define the output file name for the image
 output_file = f"page_{page_num + 1}.jpg"
 
 # Step 4: Save the image as a JPG file
 pix.save(output_file)
 print(f"Saved {output_file}")

# Close the document
doc.close()

print("All pages have been converted to JPG!")
 

Explanation of the Code

Here’s what each part of the code does:

• Importing PyMuPDF: This imports the library so we can use its functions.
• Opening the XPS File: Load the XPS file into a doc object.
• Looping Through Pages: Use a loop to go through all the pages in the file.
• Rendering the Page as an Image: Convert each page to an image using get_pixmap().
• Saving the Image: Save each image as a JPG file with a unique name.
• Closing the Document: Always close the document after finishing to free up resources.

Output

After running this code, you will see a series of JPG files in your working directory, with names like page_1.jpg, page_2.jpg, etc. Each file corresponds to a page from the original XPS document.

Tips and Customizations

• Change Resolution: Control image quality by adjusting DPI using the matrix parameter.
• Handle Errors: Add error handling for missing files or unsupported formats.
• Save in Other Formats: Save the output in other formats like PNG by changing the file extension.

Conclusion

That’s it! Converting an XPS file to JPG images is straightforward with PyMuPDF. By following the steps above, you can process any XPS document and save its pages as high-quality JPG files. This can be useful for creating previews, sharing individual pages, or working with XPS content in other tools.
