What it does
Turn a square logo into a favicon.ico with every size browsers need, or a complete favicon pack for your site.
A favicon is the little icon in browser tabs, bookmarks and search results. cextool turns your logo into a favicon.ico that holds 16, 32, 48, 64, 128 and 256 px versions, so it looks sharp on every screen and in every browser.
Tick Favicon pack to get a ZIP with favicon.ico, an apple-touch-icon for iPhone home screens, 192 and 512 px icons for Android, a web manifest, and the HTML lines to paste into your site. Non-square logos are centred on a transparent square, so nothing gets stretched. Browsers pick the size they need from the ICO: 16 and 32 px for tabs, 48 px for Windows shortcuts and larger sizes for high-resolution screens and bookmarks. Each size is downscaled in steps with high-quality smoothing, so thin lines stay clean instead of turning to mush.
