How to Convert VCF Files to MHTML Format
Converting VCF files to MHTML format using Aspose.Email for Java provides a streamlined approach to transforming contact information into a web-friendly and versatile format. This conversion process facilitates the extraction of contact details from VCF files and presents them in a structured HTML-based layout that is easily viewable in a web browser or any application supporting HTML content. By leveraging Aspose.Email for Java, users can effortlessly access and manage contact information, share contact details with others, archive vital contact details, or seamlessly integrate contact data into various web-based platforms or reporting systems. Aspose.Email for Java simplifies the conversion of VCF files to MHTML format, offering a user-friendly solution for converting and accessing contact information in a universally compatible and accessible format.
To convert VCF files to MHTML format, the library offers the MapiContact class which represents a contact in MAPI format. It is used to load, manipulate, and convert contact information stored in VCF files for various applications and integrations. The MapiMessage class provides developers with a comprehensive set of functionalities to work with email messages programmatically, enabling them to efficiently manage, manipulate, and interact with email data within their Java applications. When converting MAPI messages to MailMessage objects, the MailConversionOptions class is used to specify options for converting. The MailMessage class represents an email message and provides methods for accessing and manipulating email content, such as sender, recipients, subject, body, attachments, etc. The MhtSaveOptions class defines options for saving MailMessage objects in MIME HTML (MHTML) format. Specific settings like content encoding, boundary preservation, rendering VCard information, and including selected contact fields are configured to control the conversion output. The code sample below demonstrates the work of these classes in converting contact information stored in a VCF file to an MHTML email format. The VCF contact is transformed into a MAPI message, then converted to a MailMessage object. With the specified MHT save options, the MailMessage is saved in MHTML format with customized rendering and field inclusion settings, providing a tailored output suitable for various applications.

MapiMessage msg = MapiMessage.fromStream(new ByteArrayInputStream(os.toByteArray()));
MailConversionOptions op = new MailConversionOptions();
MailMessage eml = msg.toMailMessage(op);
//Prepare the MHT format options
MhtSaveOptions mhtSaveOptions = new MhtSaveOptions();
mhtSaveOptions.setCheckBodyContentEncoding(true);
mhtSaveOptions.setPreserveOriginalBoundaries(true);
mhtSaveOptions.setMhtFormatOptions(MhtFormatOptions.RenderVCardInfo | MhtFormatOptions.WriteHeader);

eml.save("output.mhtml", mhtSaveOptions);
What is VCF File Format?
VCF (Virtual Card Format) or vCard is a digital file format for storing contact information. The format is widely used for data interchange among popular information exchange applications. Most operating systems such as Windows and MacOS come with default applications to create and open these files. A single VCF file can contain contact information for one or multiple contacts. A VCF file usually contains information such as contact’s name, address, phone number, email, birthday, photographs and audio in addition to a number of other fields. Being supported by email clients and services, there is no loss of data during the transfer of contacts via using the vCard format. The media type for VCF file format is text/vcard.
What is MHTML File Format?
The MHTML (MIME HTML) file format is a standard for archiving and saving web pages or email messages as a single file. It combines HTML content and resources such as images, stylesheets, and scripts into a self-contained document, making it easier to share and preserve the original layout and appearance of the content. MHTML files are often used for offline viewing, archiving, or sharing web pages or emails with all their components intact.
