    The icon gets sizes from 16 to 256 pixels (no larger than the original); a non-square image is fitted into a square with transparent margins. ICO keeps no metadata.

    Usage statistics

    We count page views and operations. A random cookie identifies a browser profile; after sign-in its activity is linked to your account. Your last IP and its observation date are visible only to the site owner and kept for up to 90 days. Daily counts are kept for 90 days, and inactive profiles are removed after 90 days. Formats, outcomes, error codes, and size and time ranges are counted separately. File names, contents and metadata stay on your device. Turning this off deletes the current browser profile.

    How to convert PNG to ICO

    1. Click the box above or drag your PNG onto it — ideally a square image of 256 × 256 pixels or more.
    2. Wait a moment while your browser builds the icon. Nothing gets uploaded.
    3. Download each ICO separately or grab them all in one ZIP file.

    Why use this converter

    • Your files stay with you

      The icon is built on your device. Images are never uploaded to a server, so nobody else ever sees them.

    • Every size in one file

      The ICO holds 16, 32, 48, 64, 128 and 256 pixel versions — the system and the browser pick the one they need.

    • Transparency is kept

      A transparent PNG background stays transparent in the icon, and a non-square image is neatly fitted into a square.

    • Crisp small sizes

      Each size is downscaled separately with the Lanczos filter, so even the 16 × 16 icon doesn't turn into a blurry mess.

    Frequently asked questions

    How do I make a favicon for my website?

    Convert your logo to ICO, name the file favicon.ico and put it in the root of your site. Browsers find it on their own; to be safe, add <link rel="icon" href="/favicon.ico"> to your pages.

    Which sizes are in the icon?

    16, 32, 48, 64, 128 and 256 pixels — but none larger than the original image, so a small picture isn't blown up. An image under 16 pixels becomes a single 16 × 16 icon.

    What happens to a non-square image?

    Icons are square, so the whole image is fitted into a square with transparent margins around it. Nothing is cropped.

    Is transparency preserved?

    Yes. Each size is stored inside the ICO as a PNG with transparency — the way Windows and all modern browsers store icons.

    Will the icon work on Windows?

    Yes. An ICO with sizes up to 256 × 256 works for shortcuts, folders and apps on Windows 7, 10 and 11.

    Is it safe to convert my images here?

    Yes. The site only downloads the converter itself; your images are processed in your browser and are never sent to a server.
