Drop an image, get 16, 32, 48, 180, 192, and 512 px PNGs, plus a multi-resolution .ico for legacy browsers, plus the HTML snippet that goes in your head. Works entirely in your browser — your logo never leaves your device.
<head>
Different platforms pull different sizes. Browser tabs use 16 or 32. Bookmarks use 48. iOS home-screen uses 180. Android uses 192. PWAs use 512. Each one has its moment.
Yes, if you care about older browsers (IE < 11) or some RSS readers. Modern browsers prefer PNG favicons, but .ico is still the most universal fallback. We include one with 16, 32, and 48 embedded.
Square, high-contrast, simple. Remember it'll often render at 16×16 — that's the size of a capital letter. If your logo doesn't work at that size, simplify it before using here.
If your icon is vector-based, absolutely yes. Pass an SVG in and we'll include favicon.svg in the bundle. Browsers that support it get crisp rendering at any size; older browsers fall back to the PNG or ICO versions.
Usually at the root of your site (/favicon.ico, /favicon-32.png, etc.). Copy the HTML snippet into your <head>. That's it. No build step, no plugin.
No. All resizing and encoding happens in your browser using the Canvas API. Your logo stays on your device. You can verify by blocking our site from making network requests — the tool still works.
