How do I convert ICO to PNG?

Drop the file on this page. It runs in your browser, so there is no upload, no account and no daily limit.

Why will my software not open a ICO file?

Almost everything that is not Windows. Image editors open one grudgingly if at all, and web tools generally do not.

Why PNG specifically?

PNG is lossless and keeps transparency, which is why it is what you convert to when the result has to be exact rather than small.

Is the image uploaded?

No. It is decoded and re-encoded by the page, and no request carries it anywhere, which the network panel will show you.
