Is There a Malware-Free Offline Tool to Split Large VCF Files Quickly and Safely?

I’m trying to split a large .vcf contact file that contains over 400+ entries with complete details — names, phone numbers, emails, even contact photos. I don’t want to lose any data or formatting in the process.Most online tools I found either have file size limits or raise privacy concerns. I'm specifically looking for a secure, offline VCF splitter that doesn't share data with third parties or corrupt formatting.Does anyone know of a trusted, malware-free tool to break or split vCard files on Windows without any data loss? Also curious if any free tools are safe enough or if it's better to go with a standalone software solution.

Appreciate expert suggestions or tool recommendations!
