Favicon generator
Generate every icon a site needs from a single image: a multi-resolution favicon.ico, PNGs from 16 to 512 px, an Apple Touch icon and a PWA manifest, with the HTML to paste into your page. Browsers and phones each want a different size, and a generator produces the whole set at once. The set is built on your device, free and without an account.

This tool runs entirely in your browser — nothing is sent to a server.
The favicon is that small icon identifying your site in the browser tab, the bookmarks and mobile home screens. A serious site has one — and today several versions are needed: the historical favicon.ico, PNGs of different sizes, a 180-pixel Apple Touch icon for iOS and 192- and 512-pixel icons for the web application manifest.
Drop an image and this tool generates all those variants at once, with a preview of each size. It produces a true multi-resolution favicon.ico and provides the HTML block to paste into your page as well as a manifest example. Everything is generated locally.

Frequently asked questions
What image should I provide to start?
A square image of at least 512 pixels per side, with a simple drawing readable at very small size. A detailed logo becomes unreadable at 16 pixels: prefer a single shape or a letter, with strong contrast.
Is the favicon.ico still necessary?
It remains useful: some browsers and many aggregators still look for it at the site root, even without an HTML declaration. The file generated here contains the 16, 32 and 48 pixel resolutions in a single .ico.
Where do I place the generated files?
At the root of your site for the favicon.ico, and wherever you like for the PNGs provided you adapt the paths in the HTML block provided. Then paste that block into the <head> of your pages.
