Favicon Generator

How Favicon Generator works

Design a simple favicon from a letter or emoji, then download a multi-size .ico plus PNG versions. Everything happens inside this page: the tool reads your input, runs the calculation or conversion locally, and hands the result back to you. Nothing is transmitted, because there is no backend to transmit it to.

That design choice is deliberate. Most free tool sites upload your files to a server, process them there, and quietly keep a copy. Toolcin cannot do that — the site is a set of static files. If your connection dropped the moment the page finished loading, every tool would still work.

What actually gets written

The icon is drawn on a 512-pixel canvas, then exported as a multi-size .ico plus PNG versions. One file containing several sizes is what browsers prefer — they pick the size that fits the tab, the bookmark bar or the home screen instead of rescaling a single large image.

The .ico container is built in the page; nothing is converted on a server, so the logo you type never leaves your machine.

Letter, colours and shape

Up to three characters fit in the letter field. One character reads best at 16 pixels — the size a browser tab actually uses — because anything longer turns into a smudge at that scale.

Shape matters more than it looks: a rounded square reads as an app icon, a circle reads as a profile badge, and a plain square is the safest when the icon sits on an unknown background. Pick colours with strong contrast against each other; a subtle palette is invisible at 16 px.

Installing it

Drop the files in your site root and reference them with a link tag: an .ico at /favicon.ico is picked up even without a tag, which is why it is worth using that filename. Add an SVG favicon as well if you have one — modern browsers prefer it and it stays sharp at any size.

Browsers cache favicons aggressively. After replacing one, a hard reload or a new private window is usually needed before the change appears.

Good to know

• Works offline once loaded, including on flights and in locked-down networks.
• No file size limit beyond your device's own memory.
• Free to use, with no account and no usage counter.
• Results are produced locally, so they are not logged or shared with anyone.
