Every favicon size, one upload
Modern sites need favicons in several sizes: 16 and 32px for browser tabs, 180px for Apple touch icons, and 192/512px for Android and PWA home screens. Upload one square image (512×512 works best) and download each size individually, with the HTML snippet ready to paste.
Tip: start from a simple, high-contrast square image — fine details vanish at 16×16. Processing is fully local.
