Convert HEIF to MONO

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.

The MONO file extension stands for "Monochrome Bitmap" and is used for storing raw bi-level bitmap images, which are essentially black-and-white images without any color or grayscale. This format is primarily utilized in applications requiring simple, high-contrast images, such as fax transmissions and certain types of document scanning. The MONO format, characterized by its least-significant-byte first order, has been supported by various image processing tools. Its history traces back to early bitmap graphics needs, emphasizing simplicity and efficiency in image storage and processing.
