If you have LaTeX installed you can download as PDF directly from Jupyter notebook with File -> Download as -> PDF via LaTeX (.pdf). Otherwise follow these two steps.

1. For HTML output, you should now use Jupyter in place of IPython and select File -> Download as -> HTML (.html) or run the following command:

    jupyter nbconvert --to html notebook.ipynb  
   

   This will convert the Jupyter document file notebook.ipynb into the html output format.

   Google Colaboratory is Google's free Jupyter notebook environment that requires no setup and runs entirely in the cloud. If you are using Google Colab the commands are the same, but Google Colab only lets you download .ipynb or .py formats.

2. Convert the html file notebook.html into a pdf file called notebook.pdf. In Windows, macOS (brew install wkhtmltodf) or Linux, install wkhtmltopdf. wkhtmltopdf is a command line utility to convert html to pdf using WebKit. You can download wkhtmltopdf from the linked webpage, or in many Linux distros it can be found in their repositories.

    wkhtmltopdf notebook.html notebook.pdf   
   

Original (now almost obsolete) revision: Convert the IPython notebook file to html.

^{ipython nbconvert --to html notebook.ipynb}
