Favicons: what they are and which sizes to ship
What is a favicon?
A favicon is the tiny icon browsers show in tabs, bookmarks, history, and shortcuts. Despite its size, it's one of the most-seen pieces of your brand — it appears every time someone has your site open.
The classic format is favicon.ico, a single file that can hold multiple sizes so the browser picks the best one for each context.
Which sizes do you need?
| Size | Used by |
|---|---|
| 16×16 | Browser tabs, bookmarks, history |
| 32×32 | Modern browser tabs, taskbar shortcuts |
| 48×48 | Windows site shortcuts |
| 64×64 | High-DPI displays |
| 128×128 | Some app manifests |
| 256×256 | Pinned tiles, app icons |
For most sites, 16 + 32 + 48 covers everything. Add 128/256 if you also want a home-screen or tile icon.
How to use the result
Put favicon.ico at the root of your site, and/or link specific sizes in your HTML head:
<link rel="icon" href="/favicon.ico"> — the browser picks the best size from the .ico automatically. For PNG favicons, add a <link rel="icon" type="image/png" sizes="32x32" href="/favicon-32.png"> per size.
Frequently asked questions
Is this favicon generator really free?
Yes — free with no account, no watermark, and no limits.
What's inside the favicon.ico?
A standard ICO container with your image rendered at each selected size, stored as PNG data (the modern ICO format every browser supports).
Should I use a transparent PNG as input?
Yes — favicons usually sit on a browser tab, so transparency lets your icon shape show cleanly instead of a solid background box.
Are my files uploaded to a server?
No. All processing happens locally in your browser. Your files never leave your computer — close the tab and nothing remains.
