Turn an image — or just a letter or emoji — into a full set of favicon PNGs (16, 32, 48, 180, 192 & 512 px) plus ready-to-paste HTML. Everything runs entirely in your browser; nothing is ever uploaded.
Square images work best. Non-square images are centred and fit inside the icon.
Tip: emoji are drawn on the chosen background. For a transparent emoji icon, pick a background then set shape — or use image mode with a transparent PNG.
This is your source icon at 128 px. Below it is downscaled to each favicon size using high-quality canvas smoothing.
Standard names: favicon-16x16.png, favicon-32x32.png, favicon-48x48.png, apple-touch-icon.png (180), icon-192.png, icon-512.png.
Put the PNG files in your site root (or adjust the paths). The 192 & 512 px icons are also referenced by a web app manifest for installable PWAs.
