This page explains what a GEDCOM is, how to use WikiTree to compare people in your GEDCOM with profiles already on WikiTree, how to share your GEDCOM with WikiTree, and how to download a GEDCOM from WikiTree. Please read WikiTree is Different to understand more about what it means to share your GEDCOM on WikiTree.


What is a GEDCOM?

GEDCOM, which stands for GEnealogical Data COMmunication, is a file format for transferring family tree information.

The GEDCOM standard has been almost-universally adopted by major genealogy websites and software tools. This is good for everyone. It means that you aren't locked-in to one tool. You can move and copy your information. It helps ensure that the work you put into your family tree research won't ever be lost.

Uploading a GEDCOM

Click here to upload your GEDCOM.

Uploading involves no obligation. You can even do it as a guest without becoming a full member. You'll be presented with a neat "GEDCompare" report that shows you which family members might already exist on WikiTree. Try it!

Note: GEDCOMs with more than 5,000 people cannot be uploaded and will need to split up.

Importing a GEDCOM

After uploading and GEDCompare, if you want to help with our mission to create a single, shared family tree as a Wiki Genealogist, you can add branches to WikiTree by importing your GEDCOM.

Our GEDCOM import process is different than what you might have experienced on other sites. For a great step-by-step guide to the import process, complete with screenshots, see this post by blogger Randy Seaver.


  • GEDCOMs with more than 2,500 people cannot be imported.
  • GEDCOMs with more than 100 people and no sources cannot be imported.
  • GEDCOMs with more than 500 suggested matches cannot be imported.
  • You may import multiple GEDCOMs, but please wait until the first GEDCOM file is completely processed before uploading another.
  • Additional GEDCOM imports will not automatically replace profiles created through previous imports. Duplicates need to be skipped during the GEDCompare process.
  • All GEDCOMs are reviewed by a WikiTree team member prior to import.
  • Individuals born prior to 1700 will be automatically skipped.
  • See Before importing a GEDCOM for important information.
