HEIC

HEIC is a modern image format that offers superior compression techniques compared to JPEG, allowing for high-quality images at smaller file sizes. This innovative format supports features like multiple images in a single file and advanced audio-visual capabilities, making it ideal for photography and mobile applications. Utilize HEIC for efficient storage without compromising image quality.

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.
