The HPGL file extension, short for Hewlett-Packard Graphics Language, is a file format and printer control language developed by Hewlett-Packard in 1977 for use with their plotter printers, starting with the HP-9872. HPGL files contain commands that instruct plotters to draw images using lines rather than dots, making them essential in CAD applications and technical drawings. The language uses a series of two-letter codes followed by parameters to control the plotter's actions, such as moving the pen or drawing shapes.
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.
