Format Details
JXL
JPEG XL (JXL) is a next-generation image codec designed as a long-term replacement for JPEG, PNG, and GIF. It offers significantly better compression than JPEG (often 60% smaller at equivalent quality), supports lossless compression, animation, and HDR color. A unique feature of JPEG XL is its ability to losslessly re-encode existing JPEG files, saving storage space without any quality degradation.
ICO
ICO is the Windows icon file format used to display icons for applications, files, folders, and shortcuts in the operating system. It can contain multiple image sizes and color depths within a single file, ensuring icons look sharp at different display scales and DPI settings. ICO files are also used as website favicons — the small icon displayed in browser tabs, bookmarks, and address bars.
