Convert ttc to otb

What is the difference between .ttc and .otb?

Description: The TrueType Font Collection (TTC) file type is a container format that can hold multiple TrueType fonts (TTF) within a single file. This format is designed to optimize storage and sharing of font families or closely related fonts by combining them into a single file, reducing the overall file size compared to storing each TrueType font individually. TTC files are supported by various operating systems and software applications for desktop publishing and graphic design, allowing users to efficiently manage and use multiple fonts.; The OTB (Nokia Over The Air Bitmap Image) file format is a type of image file developed for use on Nokia mobile devices. These files are specifically optimized for efficient transmission and display on Nokia phones, particularly older models. The OTB format is designed to be compact to facilitate over-the-air (OTA) transmission, which was an essential feature in the era of limited bandwidth and data transfer capabilities. The format supports monochrome graphics, making it suitable for simple images like icons and logos.
