Free haplogroup finder
Find your haplogroup from raw DNA
Drop your raw DNA file from 23andMe, AncestryDNA or WeGene, a whole-genome VCF, or another raw data export. You get your maternal haplogroup (mtDNA) and, if the file has a Y chromosome, your paternal haplogroup (Y-DNA), with how sure each placement is.
It runs in your browser. Your file is never uploaded, there is no account, and it is free. Your browser downloads the two public haplogroup trees from this site; nothing from your file is sent anywhere. We count that a search ran and whether each line was found, never which haplogroup.

The free DNA report reads the same file for ancestry across 15 world regions, traits, medication genes and both family lines. Your DNA story opens straight away with no account; the full report opens after a code sent to your email.
How the haplogroup finder works
- It reads only the mitochondrial and Y-chromosome positions in your file. A genotyping chip carries a few hundred to a few thousand of them; a whole-genome VCF carries nearly all.
- Your maternal line is matched against PhyloTree Build 17, the standard mtDNA tree, with the same scoring Haplogrep uses. Your paternal line is followed down the YFull tree, branch by branch, as far as your file’s variants support it.
- It stops where the evidence stops. Positions your file doesn’t list are not counted as a match, so a chip often gives a main branch and a few levels below it, and a whole genome goes deeper. A full mtDNA sequence or a Big Y test goes deepest.
- It runs on the same code as the free report at /dna, which shows both lines too.
Questions
How do I find my haplogroup from raw DNA data for free?
Drop your raw DNA file on healthosx.com/dna/haplogroup. It reads the mitochondrial and Y-chromosome positions in a 23andMe, AncestryDNA or WeGene export, or a whole-genome VCF, and places you on PhyloTree Build 17 (maternal line) and the YFull tree (paternal line). It runs in your browser: free, no account, and the file is never uploaded.
Which raw DNA files work?
23andMe and AncestryDNA exports usually include both sets of positions, and so do whole-genome VCFs on GRCh37 or GRCh38, plain or .vcf.gz. Some exports, such as FamilyTreeDNA’s Family Finder file, leave them out; the finder tells you when yours has none. A zipped download works as it is.
Can a woman find her paternal haplogroup?
Not from her own DNA: the Y chromosome passes only from father to son. Her father’s or a brother’s raw file carries the line, and the finder reads it the same way.
Why is my haplogroup different from the one my testing company gave me?
Different trees, different names and different depths. Companies use their own trees; this finder uses PhyloTree and YFull. Y names come in two styles, the older ISOGG labels (J1a2b) and marker names (J-P58), so one line can appear under two names. A longer name is simply a deeper branch of the same line.
Is my DNA file uploaded?
No. The file is read in your browser. The only downloads are the two public haplogroup trees, which come from this site, and nothing from your file is sent back.
What does a haplogroup tell me?
Where one line of your ancestors is common today and roughly how old that branch is. It follows your mother’s mother’s line or your father’s father’s line, two of the roughly thousand ancestors you had ten generations back, so it is not your ethnicity or nationality. For your overall ancestry, the free report at healthosx.com/dna reads the whole file.
