Convert EPSI to JXL

EPSI, standing for Encapsulated PostScript Interchange, is a file extension used primarily in the printing and graphic design industries. It stores PostScript data along with a low-resolution preview in bitmap format, facilitating the visualization of graphic content in layout applications without needing to interpret the complex PostScript code. Introduced in the 1980s by Adobe Systems, EPSI files serve as a bridge between different software applications, ensuring consistent and high-quality output in various publishing workflows. Their efficiency and adaptability have made them a standard for exchange of graphic data in professional environments.

The JPEG XL (JXL) file extension, is a next-generation image format developed by the Joint Photographic Experts Group, combining Google's PIK and Cloudinary's FUIF formats. It supports both lossy and lossless compression, offering up to 60% better compression efficiency compared to traditional JPEG, while maintaining high image quality. Standardized in 2021, JPEG XL is designed for web delivery, professional photography, and digital printing, supporting ultra-high-resolution images, wide color gamuts, and advanced features like progressive decoding and multiple layers.
