Convert to ICO
JPG, PNG or WebP. Nothing is uploaded - this runs in your browser.
PNG with transparency gives the cleanest result. Processed in your browser.
16, 32, 48 and 256 pixels are selected by default.
Drop it at your site root as favicon.ico.
16 and 32 pixels cover browser tabs and bookmarks, 48 is used by some Windows contexts, and 256 is used when the icon is shown large. A single .ico can hold all of them, and this tool writes all four by default.
For favicon.ico at your site root, yes - browsers and crawlers still request it, and it is the reliable fallback. Modern browsers will prefer a PNG or SVG you declare in a link tag.
Yes. A non-square image gets padded or cropped to fit a square icon. Start from a square PNG with transparency for the cleanest result.
Detailed logos turn to mush at 16 pixels. Use a simplified mark - a single letter or shape - for anything that will be seen that small.
Build a proper multi-resolution .ico favicon from a PNG or JPG without uploading anything. A real .ico is a container: this tool writes 16, 32, 48 and 256 pixel versions into one file so the browser can pick the right one for a tab, a bookmark or a large tile, instead of scaling a single bitmap badly. Start from a square source, ideally a PNG with transparency, and simplify the artwork - a detailed logo becomes unreadable mush at sixteen pixels across.
