Yes, it is possible to export PST contacts to VCF without Outlook by using a standalone conversion utility. Normally PST files are associated with Microsoft Outlook, but some professional tools can read PST files directly without requiring Outlook installation. Such software performs PST to vCard conversion by scanning the PST database and listing all contacts inside the interface. After previewing the contacts, users can easily extract contacts from PST file and save them in VCF format. Some utilities like WholeClear PST to VCF Converter are designed for this purpose and help users convert Outlook address book entries into vCard files that can be used in smartphones, Gmail, iCloud, and other platforms.
