The Image Certificate Maker

Making certificates for a large quantity of participants can be a tedious task for an event. This tool automates the process of creating certificates in bulk, saving time and effort.

Usage

• Clone the repo, and cd into it.
• Run init.sh to initiate the environment. This installs uv, and installs pillow as the dependency, and activates the virtual environment.

chmod +x init.sh
./init.sh

• In the repo folder, add a participants.csv where the names are listed under the name column.
• Add cert.jpg or cert.png to the folder, depending on which format you want to use.
• Import the font of your liking into the folder, and specify the filename under font_path = ""
• Run the script using uv.

For JPEG, Run

uv run jpeg.py

For PNG, Run

uv run png.py

This generates a certificates folder.

NOTE: If your certificate does not have names right in the center, you might have to adjust the y offset in the script. Moreover, if the name is too long, you might have to modify font sizes as well.

Multithreading ensures that the process is faster.
