Format Details
BMP
BMP (Bitmap) is one of the oldest raster image formats, developed by Microsoft for the Windows operating system. It stores pixel data in an uncompressed or minimally compressed form, resulting in large file sizes but perfect lossless quality. BMP is widely supported across Windows applications and is commonly used as an intermediate format in image processing workflows.
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.
