How Can I Convert PNG to ICON on Windows PC for Free?

I don't think using Online converters to convert PNG to ICO a wise approach. Online converters can raise security concerns. You're essentially uploading your file to a third-party website, which can be a risk if you're dealing with sensitive data or confidential information. I mean, who knows what kind of data harvesting or malware might be lurking on those websites? Online converters usually have file size limits, which can be a problem if you're working with large files. You might end up having to split your file into smaller chunks, which can be frustrating and time-consuming.
