Upload your .csv file to the CoolUtils converter and click Download. The converter reads the header row, maps standard column names (First Name, Last Name, Email, Phone, Mobile, Company, Address) to vCard properties, and writes each row as a BEGIN:VCARD...END:VCARD block in the output .vcf file. The result imports directly into iPhone, Android, Outlook, and Gmail Contacts. Files up to 50 MB, no signup.

The online converter processes one file at a time. For batch conversion of multiple CSV exports — for example, converting monthly CRM exports to VCF for distribution — use the desktop Total CSV Converter. It processes entire folders in a single run and supports command-line execution for automated contact synchronisation pipelines.

The online converter produces vCard 3.0 (RFC 2426), which has universal support across all devices and applications including older iOS and Android versions. vCard 4.0 (RFC 6350) adds support for additional field types and encodings but has patchy support in older applications. For maximum compatibility — ensuring the VCF imports on every device your recipients use — vCard 3.0 is the correct choice.
