How to Convert Thunderbird Contacts to VCF

The vCard format, or VCF, is a personal data format that acts as an electronic business card. A VCF file can contain names, e-mail addresses and URLs, telephone numbers, addresses and multimedia information, including photos and audio files. Mozilla Thunderbird, a free, open-source e-mail client, does not directly support VCF. However, a free Thunderbird add-on is available that allows the export and import of VCF files, as individual contacts and all address book contacts. These VCF files can be imported to other e-mail clients, such as Microsoft Outlook, or to mobile phones.

Skill level:
Moderately Easy


  1. 1

    Navigate to the Kaosmos website at Click "MoreFunctionsForAddressBook" in the left pane and download the version of the add-on appropriate for your version of Thunderbird from the bottom of the page.

  2. 2

    Open Thunderbird. Click "Tools," then "Add-Ons." Click "Install" and double-click the MoreFunctionsForAddressBook XPI file you downloaded. Click "Install Now." Click "Restart Thunderbird" when the installation is complete.

  3. 3

    Click "Address Book." Highlight the address book you want to export in the Address Books panel. Click "Tools" and select "MoreFunctionsForAddressBook."

  4. 4

    Click "Actions For Address Books" and click "Export As VCF." Enter a name for the VCF file and click "Save."

Tips and warnings

  • You can also export your contacts as LDIF, CSV or TXT and use a third-party converter to convert these files to VCF.
