Frequently asked

Which sizes do I actually need?

For most sites: favicon.ico (32×32), apple-touch-icon.png (180×180), and a web app manifest with 192×192 and 512×512 for PWAs. The 16×16 is auto-derived by browsers from favicon.ico.

Can I upload an existing image?

Not yet — the current version generates from text/emoji only. Image upload with automatic crop and resize is planned.

Where do I put the downloaded files?

The root of your site (e.g. `/favicon.ico`, `/apple-touch-icon.png`), and reference them in your HTML `<head>`. Modern frameworks like Next.js can auto-link them if you drop the files in the right folder.
