Favicon generator
Turn an image into a complete favicon set — the .ico, the PNG icons modern browsers and phones use, and the HTML to paste in. It's all made in your browser; your image is never uploaded.
Paste this into your page's <head>
Then upload the files from the zip to your site's root folder (next to your main page).
What makes a good favicon
A favicon is the tiny icon in a browser tab, a bookmark, or a phone home screen. Because it can appear as small as 16 pixels across, detail is the enemy. A full logo with words turns to mush at that size. A single bold shape, a monogram, or a simplified mark reads clearly. Start from a square image so nothing gets cropped or stretched.
Why so many files
Different places want different formats. Browsers still request a favicon.ico that bundles several small sizes; modern browsers prefer a PNG; iPhones use a 180-pixel "apple touch icon" for the home screen; and Android's install feature reads 192 and 512-pixel PNGs from a manifest. This tool produces all of them from your one image, so every device gets a crisp icon, and gives you the HTML link tags that point to them.
How it works, and where your image goes
Your image is drawn onto canvases at each required size and encoded right here in the page — the .ico is assembled byte by byte in your browser. Nothing is sent anywhere. When you're done, download the zip, drop the files into your website's root folder, and paste the provided tags into the <head> of your pages.
