How to Make a Favicon (favicon.ico) From a PNG Logo
To make a favicon, drop a square PNG logo (256×256 or larger) into anyview.dev and click “ICO”. You get a favicon.ico containing 16–256 px sizes. Upload it to your site root and add <link rel="icon" href="/favicon.ico">.
Prepare the image
A square PNG of at least 256×256 works best. Simple shapes stay recognizable at 16 px, and a transparent background blends with any tab color.
Create the ICO
Upload the PNG to anyview.dev and click ICO. The favicon.ico includes 16, 32, 48, 64, 128 and 256 px. Non-square images are centered with transparent padding.
Add it to your site
Put favicon.ico at your site root and add <link rel="icon" href="/favicon.ico" sizes="any"> inside <head>.
For iPhone home screens, also add a 180×180 PNG with <link rel="apple-touch-icon" href="/apple-touch-icon.png">.
Not updating?
Browsers cache favicons aggressively. Hard-refresh (Ctrl+F5 / ⌘+Shift+R) or check in a private window.
