About this tool

Generate a complete, modern favicon set from a single source image. Privvert produces the classic favicon.ico (with multiple embedded sizes), modern PNGs at every size browsers ask for, and the Apple touch icon for iOS home-screen shortcuts.

You also get a site.webmanifest snippet and the exact <link> tags to paste into your <head>. Drop in a 512×512 source PNG (square, ideally with a transparent background or solid color), download the ZIP, and unpack it at your site root.

Modern browsers, iOS Safari, Android Chrome and Windows tile thumbnails each want a different icon size and format. Privvert generates the full set in one pass (16, 32, 48, 64, 128, 180, 192, 256, 512 px plus a multi-resolution favicon.ico) so you can drop a single SVG or PNG in and walk away with a complete favicon bundle ready for production.

Frequently asked questions

What HTML do I need to add?

The included README has the exact tags and the manifest reference to paste into your . Three lines is usually enough.

Why so many sizes?

Different platforms use different sizes - browser tabs (16, 32), Windows taskbar (48), Android home screen (192, 512), iOS home screen (180). Covering all of them means your icon looks crisp everywhere.

Can I use a non-square source?

You can, but the result will be cropped to a square. For best results, start with a square logo on a clean background.

What about dark mode?

Dark-mode favicons are an emerging spec (prefers-color-scheme on ). For now, pick a logo that works on both light and dark browser chrome.

Do I still need favicon.ico in 2026?

Yes - older Windows browsers and some RSS readers still request /favicon.ico by name. The ICO file Privvert generates packs 16×16, 32×32 and 48×48 into one file so it covers those legacy clients.

What about dark mode favicons?

Safari and a few other browsers respect a separate dark-mode SVG via the media query in your . Generate two versions and link both with media="(prefers-color-scheme: dark)".
