What is vcf file?

File type category:

Date updated: December 30, 2024

File extension vcf is most likely best known for its use for vCard format, universal standard for storing personal or business contacts, including such data as name, e-mail, social networks, address, or phone numbers.

These files are frequently used for import and export of contacts between two programs or devices and their respective address books. They can also be send as e-mail attachments.

The VCF format is well-supported in apps and programs on both desktop (Windows, Mac, Linux) and mobile platforms (Android, iOS, Windows). Unfortunately, some programs have difficulties with reading .vcf files that contain more than one contact.

For example, certain versions of Microsoft Outlooks only import the first contact from the file. Hence why it is usually best to export contacts on file per contact basis to avoid possible complications.

The internal structure of .vcf files may wary a little and special tags may be used by some programs.

In Google Android for example, contacts are stored in a single .vcf file and separated by tags BEGIN and END. When exported to memory card, these files can be found in the System/PIM subdirectory on the memory card and named PIM00001.vcf, PIM00002.vcf and etc. The highest number represents the latest version of the contacts and the lower numbers the previous versions.

MIME types:
text/x-vcard

How to open vcf file?

The .vcf files are natively launched in Windows Contacts program, while on Mac these are opened in the Address Book application.

Other than that, many 3rd party apps support vCard format and can read or import contacts from it.

How to convert vcf file?

Contacts in VCF (vcard) format can be converted to several suitable formats, for example CSV (Comma Separated Value). Most PIMs can do this.

Variant Call Format

File type category:
Text file

Date updated: October 27, 2026

VCF was developed for large-scale genotyping and DNA sequencing projects, including the 1000 Genomes Project. A file normally contains metadata header lines followed by tab-delimited records describing variants.

Variant records can include the chromosome or contig, position, identifier, reference and alternate sequences, quality, filtering status and additional information. Optional columns store sample-specific data such as genotypes and other values defined by the format's FORMAT field.

VCF is platform-independent and remains widely used in modern sequencing and genetics workflows. It is handled by many variant-calling, quality-control, annotation and genome-visualisation tools.

How to open vcf file?

A vcf file can be read as text with any text editor, although long files are easier to inspect with a specialised bioinformatics tool. Utilities such as bcftools and VCFtools can inspect and process VCF files, while compatible genome browsers can display their variants.

It does not need to be opened in a DNA sequencer. To analyse the data, import it into a variant-analysis or genome-visualisation program that supports VCF.

How to convert vcf file?

VCF is primarily an interchange format, so it is usually filtered, normalised or annotated rather than converted for its own sake. Tools such as bcftools can convert compatible data to related formats, including the binary BCF format, or export selected fields as tabular text.

Conversion to formats such as BED or a spreadsheet is possible for particular uses, but it can discard metadata, genotype fields or other information. The required output format should therefore be chosen before conversion.
