Understanding and using a GEDCOM file

The GEDCOM format lets a family tree travel between different software. Here's how to get one and turn it into a printable tree.

What is a GEDCOM file?

GEDCOM (GEnealogical Data COMmunication) is a text file format created so genealogy software can exchange a family tree without losing information. A GEDCOM file usually has the .ged extension.

In practice, it contains a list of individuals (birth and death dates, names, sex) and families (unions, parent-child links), tied together by internal identifiers. It's the same file most genealogy software can both import and export.

What's inside a GEDCOM file

A typical GEDCOM groups three kinds of information: individuals (one record per person, with their known events), families (linking a couple to their children), and sometimes sources (civil records, censuses) documenting each fact. Gedcom Tree focuses on individuals and families to build your visual tree.

How to export a GEDCOM file

Nearly every genealogy program offers a GEDCOM export option, usually under a "File" or "Export" menu. MyHeritage, Ancestry, Geneanet, Geni, Heredis, FamilySearch and Gramps can all produce this file in a few clicks.

Once the file is exported to your computer or phone, it's ready to be imported into any compatible service, including Gedcom Tree.

Turning your GEDCOM into a printable tree

Upload your file from the home page: Gedcom Tree analyzes it instantly and shows a free preview across 3 generations, with a watermark. You can then pick a graphic style and, if you'd like, unlock the HD version with no watermark, more generations, ready to print or frame.

Common issues

The file is rejected: check that it's a standard GEDCOM export (.ged, .gedcom or .txt) rather than a proprietary save file from the software.

Some characters look wrong: some older software exports in a legacy encoding rather than UTF-8; re-exporting from a recent version of the software usually fixes it.

No one shows up: the file may be empty of individuals, or got corrupted during transfer; try exporting it again.
