    How to convert PNG to ICO

    1. Tick the icon sizes you want. 16, 32 and 48 pixels are ticked for you.
    2. Drag your PNG onto the box, or tap it to choose a file.
    3. Check the preview and the list of sizes under the file name.
    4. Press Download ICO to save the icon.

    What you get

    • One .ico file that holds every size you ticked, from 16 up to 256 pixels.
    • Transparent areas stay transparent.
    • Images that are not square are centered and padded with transparency, so nothing gets stretched.
    • PNG, JPG, WEBP, GIF and SVG all work as the starting image.

    How to use the ICO file as a favicon

    Name the file favicon.ico and upload it to the main folder of your website, so it opens at yoursite.com/favicon.ico. Browsers look there on their own.

    You can also point to it in the head of your pages with <link rel=”icon” href=”/favicon.ico” sizes=”any”>. On WordPress, you can set a Site Icon under Appearance, Customize, Site Identity instead.

    Which sizes should I pick?

    16 and 32 pixels are used in browser tabs and bookmarks. 48 pixels is used on the Windows desktop, and Google asks for favicons that are a multiple of 48 pixels. Add 256 pixels if the icon is for a Windows program or shortcut.

    Start from a square image of at least 256 × 256 pixels. Small details get lost at 16 pixels, so a simple shape or a single letter works best.

    Frequently asked questions

    Is this a real ICO file or a renamed PNG?

    It is a real ICO file. Each size is stored as a PNG image inside the ICO container, which Windows Vista and later and all current browsers support.

    Can I convert several images at once?

    Yes. Drop in more than one file and each one becomes its own ICO file.

    Why does my icon look blurry at 16 pixels?

    There are very few pixels to work with at that size. Use a bold, simple design and avoid thin lines and small text.
