AVIF

The AVIF image format is an advanced image codec derived from AV1, offering superior compression and visual quality compared to traditional formats like JPEG and PNG. Ideal for web use, AVIF supports transparency and HDR, making it perfect for both graphics and photography. With a smaller file size and high fidelity, AVIF enhances load times without sacrificing image clarity, optimizing websites for performance and user experience.

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.
