Cross-Platform tips

📐

A multi-size .ico is one file that contains all the sizes you need. The OS or browser picks the closest size to what it needs.

💡

Including all six standard sizes adds only a few KB compared to a single size — there's essentially no cost to including everything.

🌐

Browsers use 16×16 for tabs, 32×32 for high-DPI displays. macOS Safari sometimes uses 48×48. Including all three covers every browser.

📱

For mobile bookmarks, both iOS and Android prefer separate touch icon files (180×180 PNG for iOS, manifest icons for Android), not .ico.
