Which favicon sizes do you need?
What 16/32/48 ICO, 180 Apple Touch, and 192/512 PWA icons are for — and how to link them in HTML.
A classic favicon.ico often embeds 16, 32, and 48 px for tabs and bookmarks.
iOS home screens prefer a 180×180 apple-touch-icon.png.
PWA / Android usually want 192 and 512 PNGs listed in site.webmanifest.
This tool builds those files locally and gives you a copy-paste <link> snippet.
