Build a multi-gen family tree with photos. Save JSON, export PNG / PDF.
Build a multi-generational family tree visually. Add people with name, birth / death year, gender and an optional photo. Link parents, spouses and children with a couple of clicks. Auto-layout keeps generations aligned, drag to reposition, click to edit, hide / unhide branches. Save your tree as JSON to keep editing later, or export as a PNG / PDF poster for the family reunion. Fully offline — your genealogy data never leaves your device.
Family Tree Builder provides a straightforward, visual way to construct multi-generational family trees and ancestor charts directly in your browser. With automated generation layout, photo support, and flexible JSON saving alongside PNG and PDF poster exports, it simplifies genealogy mapping without requiring software installations or account signups. Because it operates fully offline, your sensitive family data remains entirely on your device.
Good to know: Very large historical databases requiring advanced archival record searching or collaborative multi-user editing may require specialized genealogy software or dedicated online platforms.
