Honestly, it depends on how often and how big your VCF files are. A free VCF splitter can help if you only want to test the process or split a few contacts but most free tools come with limits (like splitting only 10-20 contacts) and lack advanced features. On the other hand, a paid VCF splitter tool like WholeClear Split vCard Software is more reliable. It allows you to split vCard files of any size keeps all details safe, and works offline without errors. I personally prefer the paid option because it saves time, ensures data accuracy and offers customer support. You can still try the free demo first before upgrading.
