It always seemed a bit risky to me to upload personal contacts to Internet tools, especially when the data was from the business side. I was looking for an offline method to split VCF files without any risk of data loss and still keep all the details. Nearly all the free VCF splitter websites ask for uploads and do not have version control. I finally came to a solution with DataVare Split vCard Software, which is 100% offline and supports vCard 2.1, 3.0, and 4.0 formats. It not only accurately splits VCF contacts but also can convert them into formats such as CSV or PST if required. By doing it this way, I was able to split VCF files without any doubts regarding my privacy, so it was a viable alternative to the browser-based split VCF software.
