PNG to ICO: questions
What sizes does a favicon.ico need?
16 and 32 px cover browser tabs; 48 px is used by Windows; the larger sizes serve high-DPI screens. This tool includes them all.
Can I use SVG or JPG as the source?
Yes, any supported input works; SVG gives the crispest small sizes.
How do I add it to my site?
Upload favicon.ico to your site’s root folder, or add <link rel="icon" href="/favicon.ico"> in the page head.
