Free favicon checker

There isn’t one size. Browser tabs draw it at 16 or 32 pixels, Google recommends a square icon bigger than 48 × 48, an iPhone wants 180 × 180 and Android wants 192 and 512. The simple set is an SVG, a 32px favicon.ico, a 96px PNG, a 180px apple-touch-icon and a web manifest with the two Android sizes.

Google only shows a favicon it can crawl. The icon has to be square, at least 8 × 8 pixels (bigger than 48 × 48 is recommended), linked from your home page, and not blocked for Googlebot-Image in robots.txt. The checker tests the shape, the size and robots.txt. After a fix it’s a wait: Google picks the icon up when it next crawls your home page, which takes a few days to a few weeks.

Paste your link in the box at the top of this page. You’ll see the icon in a light and a dark browser tab, a Google result and on two phone home screens, plus a checklist of the files and sizes you’re missing. To test a site before it’s live, put it on a public preview address first. We can’t reach localhost.

Yes, it’s worth keeping. Every modern browser reads a PNG or SVG link, but feed readers, some crawlers and old browsers only ever ask for /favicon.ico. Without it they get a 404 on every visit. One 32px file at the root of your site covers them.

180 × 180 pixels, as a PNG with no transparency. iOS rounds the corners itself, so keep the image square and fill it to the edges. A see-through one gets a black background on the home screen. Name it apple-touch-icon.png and put it at the root, and an iPhone finds it even without a link tag.

Yes. Chrome, Edge and Firefox all read an SVG favicon, and it stays sharp at every size. Keep a PNG or .ico beside it though. Google’s list of favicon formats doesn’t include SVG, and older browsers and feed readers skip it.

Yes, two ways. An SVG favicon can carry a prefers-color-scheme rule inside the file and swap its own colours. Or you add a second icon link with media="(prefers-color-scheme: dark)". Without either, a dark see-through icon can vanish on a dark tab.

Because it’s cached. Browsers keep favicons longer than anything else on a page, and a hard refresh often isn’t enough. Rename the file, or add ?v=2 to its link. A new address gets past every cache at once. Google is slower still and updates on its own schedule.

An Android icon made to be cropped. Each phone maker cuts home-screen icons to its own shape, so a maskable icon keeps the logo inside the middle 80% and fills the rest with background. Without one, Android shrinks your icon onto a white circle. Add it to the web manifest as its own 512px file with "purpose": "maskable".

Yes, it’s free. No account, no ads, and we don’t keep the links you check. The only limit is 10 checks a minute. There are more free tools for fonts, colours and link previews too.
