I recently exported my contacts to vCard format and after some time realized that there were a lot of duplicate entries in them. Removing these duplicates manually was not only time-consuming but also came with the risk of accidentally deleting important information. So I started looking for a tool that scans the VCF file and removes only the duplicate contacts while keeping the rest of the data intact.
After a lot of research and trying a few tools, I was very satisfied with one tool that I would like to recommend here—Softaken vCard Duplicate Remover. The biggest feature of this tool is that it scans VCF files very well and identifies duplicate contacts based on criteria like name, email, number, etc. It then gives you a clean and duplicate-free file with all your original entries intact.
I also found the interface to be very simple and clear, making it very easy to use, especially for users who are not technically proficient. It also comes with a free trial version that shows you the results beforehand by working on a limited number of contacts.
