Create Certificates using Python-PIL

  • Difficulty Level : Easy
  • Last Updated : 26 May, 2020

Prerequisites: Python: Pillow (a fork of PIL)

Well if you have ever done something like creating certificates for participants of any event, then you know how tedious process it is. Let’s automate that using Python. We will be using the Pillow module of Python. To install that simply type the following in your terminal

pip install Pillow

You also need the design of the certificate as an image format (preferably png). You can use something like Microsoft Office Publisher to create the certificates and export them as png. Keep some extra space for entering the name. Below is the template certificate we will be using.

Template Certificate:

Sample Certificate

So, our certificate template is ready. Now, we need to find a suitable font for writing the name on it. You need the path to the font file (TTF file). If you are using Windows 10, then simply search for Fonts in windows search, it will show you results of Fonts settings. Head over there and you should see something similar to the following screen.

Fonts settings

Now, choose the font you like from here and click on it. You will see a path to that font. Note down the path somewhere. You will need it in your code.

Below is the implementation.

# imports
from PIL import Image, ImageDraw, ImageFont
def coupons(names: list, certificate: str, font_path: str):
    for name in names:
        # adjust the position according to 
        # your sample
        text_y_position = 900 
        # opens the image
        img =, mode ='r')
        # gets the image width
        image_width = img.width
        # gets the image height
        image_height = img.height 
        # creates a drawing canvas overlay 
        # on top of the image
        draw = ImageDraw.Draw(img)
        # gets the font object from the 
        # font file (TTF)
        font = ImageFont.truetype(
            200 # change this according to your needs
        # fetches the text width for 
        # calculations later on
        text_width, _ = draw.textsize(name, font = font)
                # this calculation is done 
                # to centre the image
                (image_width - text_width) / 2,
            font = font        )
        # saves the image in png format"{}.png".format(name)) 
# Driver Code
if __name__ == "__main__":
    # some example of names
    NAMES = ['Frank Muller',
             'Mathew Frankfurt',
             'Cristopher Greman',
             'Natelie Wemberg',
             'John Ken']
    # path to font
    FONT = "/path / to / font / ITCEDSCR.ttf"
    # path to sample certificate
    CERTIFICATE = "path / to / Certificate.png"

Final Certificate result

Add the names to the NAMES list. Then change the font path and path to the certificate template according to your system. Then run the above code and all your certificates should be ready. This is a pretty effective solution for automating the process of creating certificates for a large number of participants. This can be very effective for event organizers.
