Is there a free tool to convert PST contacts to vCard format?

I have a PST file containing Outlook contacts, and I need to convert those contacts into vCard (VCF) format so I can import them into my mobile phone and other applications. I am looking for a free tool or method that can perform this conversion easily without losing any contact details. I tried searching online, but found many paid tools or trial versions with limitations. Ideally, I would prefer a completely free solution or a reliable freeware utility that can export PST contacts to vCard format in bulk. Has anyone here done this before? If yes, could you please suggest a trusted free tool method to convert PST contacts to VCF?
