Frequently asked questions

Which sizes should an ICO file contain?

For a website favicon, 16, 32 and 48 px are enough. For Windows app and desktop icons add 256 px (and 24, 64 or 128 for crisp list and tile views). Every size you tick is stored in the same .ico file.

Is transparency kept?

Yes. Each size is stored as a PNG inside the ICO, so transparent backgrounds and soft edges are kept. All current browsers and Windows Vista or later read this kind of ICO.

Is my image uploaded?

No. The icon is made in your browser, so your image never leaves your device.

Are my files uploaded anywhere?

No. Image to ICO Converter runs entirely in your browser. Your files are processed on your device and are never sent to a server.

Is there a file size limit?

No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.

Is Image to ICO Converter really free?

Yes. There's no account and no watermark. A short optional ad, or a 20-second wait, unlocks each download. That's how we keep it free.
