Frequently asked questions
What is a ICO file?
The icon format used by Windows and by website favicons. A single file can hold several sizes at once.
How do I open a ICO file?
You can open it right here to convert it into something more convenient. If your computer does not recognise it, the practical move is to convert it to a universal format such as JPG or PNG.
What is the maximum ICO size here?
100 MB. That is the cap we work with for this format so conversion stays fast and reliable.
Are my ICO files uploaded to a server?
No. We never receive them, so there is nothing to store and nothing to delete.
