About the formats
ICO (Windows Icon, 1985) is the icon format used by Windows and by website favicons. One ICO file can hold several sizes (16×16 up to 256×256), so the right one is shown in tabs, desktops and taskbars.
PDF (Portable Document Format, 1993) is the universal document format. A PDF looks the same on every device and printer, which makes it the safest way to send images as documents, forms or scans.
