Format Details
JPEG
JPEG (Joint Photographic Experts Group) is the most widely used lossy image compression format in the world, designed for compressing natural photographic images. It achieves high compression ratios by discarding visual detail that the human eye is less sensitive to, typically reducing file sizes by 10× or more. JPEG is universally supported across every device and application, and remains the standard format for digital photography and web images.
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.
