TIFF

TIFF (Tagged Image File Format) is a versatile graphic file format renowned for its ability to store high-quality images. Commonly used in photography, publishing, and scanning, TIFF supports multiple layers and channels, making it ideal for professional use. Its lossless compression ensures pristine image quality, providing a reliable choice for archiving, printing, and versatile editing applications.

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.
