Quick Answer
Turning a PNG logo into a favicon - free, no software - takes one upload and one download: the generator crops/pads your logo square, renders every required size (16, 32, 48 px in favicon.ico, 180 px Apple touch, 192 and 512 px Android/PWA), and hands you the files plus the HTML tags. The part worth your attention isn't the conversion, it's the 16-pixel question: will anyone recognize your logo at the size of this letter "o"?
The 16 px reality check
A browser tab gives your brand sixteen pixels. Full wordmarks, taglines, thin-line icons and anything with more than two colors degrade into mush. What survives:
- A single bold letterform - the most common professional choice.
- A geometric symbol - circles, shields, simple monograms.
- A strong color block - sometimes the brand color itself does more work than the mark.
If your PNG is the full horizontal logo, crop to the symbol before generating. A generator can resize anything; it can't make a 400-pixel-wide wordmark legible at 16.
What "a favicon" actually includes in 2026
| File | Size | Used by |
|---|---|---|
| favicon.ico | 16 + 32 + 48 in one file | Browser tabs, bookmarks, legacy |
| apple-touch-icon.png | 180 x 180 | iOS home screen, Safari |
| icon-192 / icon-512.png | 192, 512 | Android, PWA install, splash |
| site.webmanifest | - | Tells Android/PWA where the icons are |
The Favicon Generator builds the full set from one PNG and prints the exact link tags to paste into your <head> - the whole job is under two minutes.
After uploading: why the old icon won't die
Browsers cache favicons aggressively - sometimes for weeks. After deploying, test in a private window or append ?v=2 to the icon URLs in your tags. If the new icon shows there, the job is done; your regular window will catch up.

FAQ
Can I make a favicon from a PNG for free?
Yes - a browser-based generator converts one PNG into favicon.ico, Apple touch and Android icons plus the manifest, free and without uploading the file to any server.
What if my PNG logo isn't square?
The generator pads it to square (choose transparent or a background color). But for wide wordmarks, crop to the symbol first - padding a wordmark makes it tiny inside the square.
Why does my browser still show the old favicon?
Favicon cache. Check in a private/incognito window, and add a version query (favicon.ico?v=2) to the link tags to force all browsers to refetch.
