ICO is the container Windows and websites use for icons — favicons, desktop shortcuts, application icons. It is a wrapper more than an image: most tools that edit images will not open it, and most that need an image (documents, design tools, web pages) want a PNG. This converter unpacks the icon into exactly that.
The conversion happens in your browser with the transparency preserved — icon backgrounds stay transparent in the PNG, ready for editing or reuse. Multi-size ICO files decode at the size your browser selects, typically the largest icon in the file. Nothing uploads, and the result downloads instantly.

Frequently asked questions
Will the icon's transparent background be kept?
Yes — PNG carries the alpha channel across intact, so the icon stays transparent instead of gaining a white box. That is exactly why PNG is the right target for icons.
My ICO contains several sizes — which one becomes the PNG?
An ICO can pack multiple resolutions of the same icon. The browser decodes one of them — typically the largest available — and that is what the PNG contains.
Can I convert a PNG back into an ICO here?
Not yet — this page unpacks ICO into PNG. The reverse direction (building a favicon from an image) is a different tool and is on our roadmap.
Is my file uploaded to a server?
No. ConvertUno runs entirely in your browser on your own device. Your file never leaves your computer or phone — there is no upload at all.
Is it really free, with no watermark?
Yes. Processing happens on your device, so serving you costs us almost nothing — no watermark, no account, no file-size limit, no daily quota.
