Convert XPM to JXL

The XPM (X PixMap) file extension is a format used for storing pixmap images, primarily in the X Window System for Unix-based systems. Developed in the late 1980s, it allows for the storage of images in plain text, making it human-readable and editable. XPM files are mainly utilized for defining icons and graphical elements in software applications. They support transparency and can be easily integrated into programming languages such as C, enhancing the customization and visual appeal of user interfaces. The format's simplicity and flexibility have cemented its role in software development and graphical design.

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.
