Drop in a logo and get favicon.ico plus the PNG sizes browsers, iOS and Android each want, with the markup to paste into your head. Built in this tab, so an unreleased logo stays unreleased.
Square works best, at least 512 pixels. PNG with transparency is ideal.
Keep it transparent, or put it on white or black if your mark needs a solid backing.
Download each file into your site root, then paste the three lines of HTML into your head.
Guides exist that list twenty favicon files and a web manifest. Almost none of it is necessary now. A .ico containing 16, 32 and 48 pixel versions, a 180 pixel apple-touch-icon, and 192 and 512 pixel PNGs cover every browser and both mobile platforms.
The .ico still matters, because browsers look for /favicon.ico whether you asked them to or not, and a missing one means a 404 in your logs on every first visit. The file produced here holds PNG data inside the .ico container, which every current browser and modern Windows accept.
Detail is what fails at small sizes. A logo with a wordmark becomes an unreadable smudge at 16 pixels, so use the mark on its own. Test at actual size rather than zoomed in, because a favicon is only ever seen tiny.
Nothing here is uploaded. That matters more than it sounds for this particular tool, since the logo you are converting is frequently for a product that has not launched yet.
No. The work happens inside this tab, on your own machine. Open your browser's network tab while you use the tool, there is no request carrying your file.
None set by us. Very large files are limited only by your device's memory, and we warn you before that becomes a problem.
No, and there is no daily limit either. There is nothing to sign up for.
Yes. Browsers request /favicon.ico regardless of what your HTML says, so having one avoids a 404 on every first visit.
Square and at least 512 pixels. Larger is fine, it gets scaled down.
In the root of your site, next to index.html, unless you change the paths in the HTML snippet.
