Convert IPYNB (Jupyter Notebook) to HEIF

The IPYNB file extension stands for "Interactive Python Notebook" and is used exclusively with Jupyter Notebook. It is a JSON file format that contains a complete record of user sessions, including code, narrative text, equations, and visualizations. The IPYNB files facilitate reproducible research and easy sharing of data analysis workflows. Originating from the IPython project, Jupyter Notebook has expanded its capabilities to support multiple programming languages, making it a versatile tool in the data science and machine learning communities. The format's history traces back to the early 2010s when it was developed to enhance interactive computing and collaborative work.

The High Efficiency Image File Format (HEIF) is a modern image format designed for superior compression efficiency and enhanced image quality. Originating in 2015, HEIF was developed by the Moving Picture Experts Group (MPEG) and utilizes the High Efficiency Video Coding (HEVC) codec to store image data. It supports a wide range of multimedia applications, including single images, image sequences, auxiliary image items, and non-image items, making it highly versatile for professional and consumer usage in various devices and platforms. Its ability to maintain high image quality while reducing file size significantly improves storage efficiency and accelerates data transmission.
