How to Convert Graphs from Jupyter Notebook to a Single PDF File

If you've been working with graphs and visualizations in Jupyter Notebook, you may have encountered the need to compile those graphs into a single, easily shareable PDF file. Whether you are preparing a report, a presentation, or simply want to archive your findings, converting your visualizations to a PDF format can make your work more accessible and professional. In this guide, we will walk through the steps to achieve this task effectively!

The Challenge

Many users often wonder how to directly export their Jupyter Notebook graphs into a PDF. There isn’t a straightforward command in Jupyter that allows you to export graphs directly to a single PDF file. However, with a series of organized steps, you can accomplish this seamlessly. Let's take a look at how we can do this using Python and libraries like Matplotlib and PIL.

The Solution: Step-by-Step Guide

Step 1: Import the Required Library

To begin, you need to ensure that you import Matplotlib, which is essential for plotting your graphs. Simply add the following line at the beginning of your Jupyter Notebook:

Step 2: Save Each Graph as an Image

As you create graphs in different cells of your Jupyter Notebook, you should save each plot as a separate PNG file. You should ensure that each image has a unique name to avoid conflicts. For example:

This process should be done for each plotting block, incrementing the filename for each new graph (e.g., plt2.png, plt3.png, etc.).

Step 3: Convert All Images to a PDF

After saving your images, it’s time to compile them into a PDF. Add the following code to the last cell of your Jupyter Notebook to do this:

Explanation of the Code

Import Libraries: The code begins by importing the necessary libraries (PIL.Image, glob, and os).

Collect PNG Files: Using glob, it collects all PNG images saved in the directory.

Convert Images: A loop processes each image, converting them to RGB format, which is required for saving as PDFs.

Save as PDF: The first image is saved as 'plots.pdf', and the rest of the images are appended to this PDF file.

Clean-up: Finally, the code employs os.remove to delete the individual PNG files after they’ve been included in the PDF, keeping your workspace tidy.

Important Notes

Ensure that all image filenames are unique (e.g., plt1.png, plt2.png) to prevent overwriting.

Make sure there are no other PNG files in the same directory as they will be included in the PDF and deleted when the cleanup runs.

Conclusion

By following the steps outlined above, you can easily compile all your graphs from a Jupyter Notebook into a single, neatly organized PDF file. This method not only enhances the presentation of your work but also simplifies sharing and reviewing for others. Happy plotting!
