What the converter does

  • The format is detected automatically: this page takes VCF as well as AncestryDNA, MyHeritage and FamilyTreeDNA raw data.
  • Takes the whole .zip archive or the unpacked AncestryDNA.txt.
  • Joins allele1 and allele2 into a 23andMe genotype, e.g. AG.
  • Chromosomes 23, 24, 25 and 26 become X, Y, X and MT.
  • No-calls (0) are written as --, like in 23andMe.

Where can you use the result?

The 23andMe format is accepted by GEDmatch, Genomelink, Genetic Genie, Living DNA, tellmeGen and other services — see the catalog on the home page. FamilyTreeDNA accepts original files only.

Frequently asked questions

How do I download AncestryDNA raw data?

DNA → your test → DNA Settings → Download DNA data. Confirm the request and you'll get an email with a link to a .zip archive — upload it here as is.

Do I need to unpack the archive?

No. The converter takes AncestryDNA.txt out of the .zip itself. The unpacked file works too.

Why convert if services accept this format?

If a service accepts your original file, upload the original. Conversion helps when a service or a program only reads the 23andMe format, or when you want files from different companies in one layout.

Can I upload the result to FamilyTreeDNA?

No: FamilyTreeDNA accepts original files only. Upload your original AncestryDNA file there.

Is it safe?

Yes. The file is processed right in your browser, on your device: it is never sent to our server or shared with anyone. Nothing is kept after you close the tab.
