“Python Saving Multiple Figures Into One Pdf File” ~ bbaz
Introduction
Are you tired of having to save each individual Python figure one by one? Say no more. With just a few lines of code, you can easily save multiple Python figures as one PDF file. In this blog article, we will compare different methods and libraries to achieve this without any hassle.
Using PdfPages from Matplotlib Library
One way to save multiple Python figures as one PDF file is by using PdfPages from the Matplotlib library. The PdfPages class allows you to add multiple pages to a single PDF file. Below is an example code:
# import required librariesimport matplotlib.pyplot as pltfrom matplotlib.backends.backend_pdf import PdfPages# create a new PDF filewith PdfPages(my_figures.pdf) as pdf: # plot first figure fig1 = plt.figure() plt.plot([0, 1, 2], [1, 3, 2]) # add the first figure to PDF file pdf.savefig(fig1) # plot second figure fig2 = plt.figure() plt.plot([0, 1, 2], [2, 2, 2]) # add the second figure to PDF file pdf.savefig(fig2)Pros
- Easy to use with existing Matplotlib plots
- No external libraries needed
Cons
- Only works with Matplotlib plots
- May require extra steps to format multiple plots correctly
Using FPDF Library
Another way to save multiple Python figures as one PDF file is by using the FPDF library. This library allows you to create a PDF file from scratch and add custom elements, including images and graphs. Below is an example code:
# import required librariesfrom fpdf import FPDFimport matplotlib.pyplot as plt# create PDF objectpdf = FPDF()# add a new page to the PDF filepdf.add_page()# plot first figurefig1 = plt.figure()plt.plot([0, 1, 2], [1, 3, 2])# save the first figure to a PNG imagefig1.savefig(figure1.png)# add the PNG image to PDF filepdf.image(figure1.png, x=10, y=50, w=100)# plot second figurefig2 = plt.figure()plt.plot([0, 1, 2], [2, 2, 2])# save the second figure to a PNG imagefig2.savefig(figure2.png)# add the PNG image to PDF filepdf.image(figure2.png, x=10, y=100, w=100)Pros
- Allows customization of PDF file
- Can be used with other libraries and tools to create complex PDF files
Cons
- Requires the installation of an external library
- May require extra steps to format multiple plots correctly
Using PyPDF Library
The PyPDF library is another way to merge multiple PDF files into one file. This method involves saving each individual plot to a separate PDF file and then merging them together. Below is an example code:
# import required librariesimport matplotlib.pyplot as pltfrom PyPDF2 import PdfFileMerger# create a PDF file for each plotfig1 = plt.figure()plt.plot([0, 1, 2], [1, 3, 2])fig1.savefig(figure1.pdf)fig2 = plt.figure()plt.plot([0, 1, 2], [2, 2, 2])fig2.savefig(figure2.pdf)# merge the PDF files into one filepdf_merger = PdfFileMerger()pdf_merger.append(open(figure1.pdf, rb))pdf_merger.append(open(figure2.pdf, rb))with open(my_figures.pdf, wb) as pdf_output: pdf_merger.write(pdf_output)Pros
- Can be used with any method of saving plots to PDF files
- No external libraries needed for creating plots
Cons
- Requires the installation of an external library
- May require extra steps to format multiple plots correctly
Comparison Table
Below is a comparison table between the three methods discussed above:
| Method | Pros | Cons |
|---|---|---|
| Matplotlib’s PdfPages | Easy to use with Matplotlib plots, no external libraries needed | Only works with Matplotlib plots, may require extra steps to format multiple plots correctly |
| FPDF Library | Allows customization of PDF file, can be used with other libraries/tools to create complex PDF files | Requires the installation of an external library, may require extra steps to format multiple plots correctly |
| PyPDF Library | No external libraries needed for creating plots, can be used with any method of saving plots to PDF files | Requires the installation of an external library, may require extra steps to format multiple plots correctly |
Conclusion
Choosing the best method for saving multiple Python figures as one PDF file depends on your specific needs. If you already have Matplotlib plots and want an easy solution, PdfPages may be the best option. If you need to customize the PDF file or create more complex files, FPDF may be the way to go. If you don’t mind installing an external library and want a more versatile solution, PyPDF may be the choice for you.
Whatever your choice might be, hopefully this article has given you a good overview of the different methods available to achieve your goal.

Here are the most commonly asked questions about saving multiple Python figures as one PDF file easily:
- Why would I want to save multiple Python figures as one PDF file?
- You may want to save different plots or charts you have generated in one document for easier sharing or presentation purposes.
- You can use the pdfpages library in Python to combine multiple PDF files into one. First, save each figure as a separate PDF file, then use pdfpages to merge them into one file.
- Yes, you can use the pdfpages library to specify the layout of the figures in the merged PDF file. For example, you can arrange them in a grid or in columns and rows.
- All you need is Python and the pdfpages library. Make sure you have the latest version of both installed.
- The number of figures you can save in one PDF file depends on the size of each figure and the memory capacity of your computer. However, it is generally recommended to keep the number of figures between 5 and 10 per page for better readability.
