J2K

JPEG 2000 (J2K) is an advanced image file format that offers superior compression techniques and high-quality visuals, making it ideal for digital imaging applications. Emphasizing lossless and lossy compression, J2K is widely used in professional photography, medical imaging, and digital cinema. Its efficient data management enables faster processing and storage, ensuring optimal performance for high-resolution images.

JSON

JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. Widely used in web applications for data exchange, JSON supports a text format that is completely language-independent, making it a preferred choice for APIs and configuration files.
