CR2 to ICO — frequently asked questions
Is this CR2 to ICO converter really free?
Yes — completely free, with no sign-up, no watermarks and no daily limits.
Are my CR2 files uploaded to a server?
No. The conversion happens entirely on your device using your browser's built-in image engine. Your CR2 files never leave your computer or phone — which is also why the conversion is nearly instant.
What sizes will the ICO contain?

Is the conversion private?
Yes — your CR2 is decoded and packed into the icon entirely inside your browser via a WebAssembly build of LibRaw; nothing is uploaded.
