Favicon Generator
Generate a complete favicon set from a single image: the ICO, the PNG sizes browsers and phones ask for, a web app manifest, and the HTML to paste in. Saves the usual half hour of looking up which sizes still matter.

How it works
- 01Drop in a square image — 512×512 or larger gives the cleanest results.
- 02Generate, and every size downloads along with a favicon.ico.
- 03Copy the HTML snippet into your page's head.
Questions
- Are my files uploaded anywhere?
- No. The file is read from your disk by the browser and processed in this tab using JavaScript and WebAssembly. Nothing is transmitted, which you can verify by opening your browser's network panel or by disconnecting from the internet — the tool keeps working.
- Which sizes do I actually need?
- In practice: favicon.ico at 32px for legacy requests, a 180px PNG for iOS home screens, and 192px and 512px for Android and web app manifests. The rest are generated because some contexts still ask for them and they cost nothing to include.
- Can I use an SVG instead?
- Modern browsers support SVG favicons and they scale perfectly, but iOS ignores them and some crawlers still request favicon.ico. Shipping both is the pragmatic answer.
- Is there a catch — a limit, a watermark, a sign-up?
- None. Because the work happens on your machine rather than a server, there is no per-file cost to recover and therefore nothing to meter. No account, no queue, no watermark.
