ICO

ICO files are optimized for storing iconic images used in Windows applications, allowing for multiple resolutions and color depths. They enhance user interfaces by providing scalable and high-quality graphics for programs and shortcuts. As a versatile image format, ICO files support both static and animated icons, making them essential for software developers and designers aiming for a polished visual appearance.

FITS

FITS is a digital file format designed for the storage and transmission of scientific data, particularly in astronomy. Optimized for large datasets, it efficiently handles multi-dimensional arrays and metadata, making it indispensable for image and data analysis in telescopes and space missions. Its extensibility ensures compatibility across various platforms and software, securing its place as a vital tool in scientific research.
