Image to PDF converter in Python
About the project: This is a single-file Python script that converts one or more images into a single PDF document.
This project uses the Pillow library, which is a powerful tool for image processing in Python.
Prerequisites
Before you run the code, you'll need to install the Pillow library. You can do this easily using pip from your terminal or command prompt:
pip install Pillow
This script is simple to use. Just save it, make sure your images (JPEG, PNG, etc.) are in the same folder as the script, and run it from your terminal.
Project Level: Intermediate
You can directly copy the below snippet code with the help of green copy button, paste it and run it in any Python editor you have.
Steps: Follow these stepsStep 1: Copy below code using green 'copy' button.
Step 2: Paste the code on your chosen editor.
Step 3: Save the code with filename and .py extention.
Step 4: Run (Press F5 if using python IDLE).
