How it works

Your file is parsed locally using a pure JavaScript GEDCOM parser — nothing is sent to a server.

1. Parse GEDCOM Reads individuals (INDI), families (FAM), names, birth/death dates, and sex — all in-browser.
2. Build hierarchy Constructs a linked tree from HUSB/WIFE/CHIL references and selects the root automatically.
3. Visualize with D3 Renders a zoomable, pannable, collapsible tree using D3's tree layout and SVG.
4. Export PDF or PNG Uses pdf-lib to tile the full tree across A4 pages, or serialises the SVG to a PNG canvas.

Frequently asked questions

What is a GEDCOM file?
GEDCOM (Genealogical Data Communication) is a plain-text file format created by The Church of Jesus Christ of Latter-day Saints in 1984. It has become the universal standard for exchanging family tree data between genealogy programs such as Ancestry, FamilySearch, MacFamilyTree, Gramps, RootsMagic, and Legacy Family Tree. Each .ged file encodes individuals, families, events (births, marriages, deaths), and sources using a numbered-level text structure.
How do I export a GEDCOM from Ancestry or FamilySearch?
On Ancestry.com: go to your tree, click the tree name → Tree Settings → Export Tree → Export. On FamilySearch: open your Family Tree, click the ⋮ menu → Export GEDCOM. On MacFamilyTree: File → Export → GEDCOM. Most genealogy apps have a similar export path under File or Settings. The resulting .ged file is what you drop here.
Is my family data private — does it get uploaded anywhere?
No. This tool is 100% client-side JavaScript. Your .ged file is read directly by your browser using the FileReader API. The data never leaves your computer — no network request is made, no server processes your file. You can verify this by disconnecting from the internet and reloading the page; it still works fully offline once loaded.
How large a GEDCOM file can it handle?
The parser handles files up to several megabytes comfortably. Files with fewer than 5,000 individuals render instantly. Very large files (50,000+ individuals) may take a few seconds to parse and may render a condensed top-down view for clarity. The PDF export tiles the entire tree across as many A4 pages as needed.
What GEDCOM tags are supported?
The viewer reads: INDI (individuals) with NAME, SEX, BIRT/DATE, DEAT/DATE, BURI/DATE; FAM (families) with HUSB, WIFE, CHIL, MARR/DATE. Notes (NOTE), sources (SOUR), and multimedia (OBJE) are parsed but not displayed in the tree to keep the view uncluttered. GEDCOM versions 5.5 and 5.5.1 are fully supported; GEDCOM 7 is partially supported.
Can I search for a specific person in the tree?
Yes. Use the search box above the tree to filter by name. Matching nodes are highlighted in the tree and the view auto-centres on the first match. Press the ⟳ Reset zoom button to return to the full tree view.
