Convert MD GFM to HEIF

Markdown (MD) is a lightweight markup language with a file extension MD, commonly used for formatting readme files, documentation, and comments in GitHub repositories. GitHub-Flavored Markdown (GFM) extends the original Markdown's capabilities, adding features like tables, task lists, and auto-linking URLs. Markdown's simplicity and effectiveness in creating formatted text using a plain text editor made it widely adopted in the developer community. GFM, in particular, is optimized for use on GitHub, enhancing collaboration and code documentation.

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.
