Conversion happens on your device using your browser's own image engine. Your files are never uploaded, so there is no size limit beyond your device's memory.
Getting icons out of .ico files
ICO is a Windows container format, and most image editors either cannot open it or handle it badly. Converting to PNG gives you an ordinary image that works in any editor, design tool or web page.
Transparency is preserved, which matters for icons — they are almost always transparent around the edges, and losing that would leave an ugly square block behind the artwork.
About multiple sizes
A single .ico file often contains several resolutions of the same icon — 16×16, 32×32, 48×48 and larger — so that Windows can pick the right one for each context. Your browser selects one of them when decoding, generally the largest available, and that is what gets converted.
Frequently asked questions
Are my files uploaded to a server?
No. The conversion runs inside your browser using your device's own processor. Your files are never transmitted anywhere, which is why the tool works even if you disconnect from the internet after the page loads.
Which size do I get if the icon has several?
The browser picks one when decoding, usually the largest embedded resolution. You cannot choose a specific one with this tool.
Is transparency kept?
Yes. PNG supports full alpha transparency, so the transparent areas around the icon carry across.
Is there a file limit or a paywall?
There is no account, no watermark, and no upload cap. Because your device does the work, the only practical limit is your available memory. The site is funded by ads, not subscriptions.
