Older ICO files used (uncompressed or RLE), making file sizes large. Modern .ico supports embedded PNG compression (since Vista). Example:

To keep file sizes in check, Microsoft has also implemented advanced compression algorithms, such as the LZ77 compression algorithm used in Windows 10. This algorithm can compress icon files by up to 50%, making it possible to store high-quality icons without excessive file sizes. windows icon file size

Here are the standard dimensions found inside a modern Windows icon file: Older ICO files used (uncompressed or RLE), making

At first glance, a Windows icon seems trivial — a small graphic, barely a few kilobytes. But the .ico file format hides a surprisingly sophisticated system for managing , both in dimensions and file footprint. This algorithm can compress icon files by up
