Free GEDCOM tools that fix your file without destroying it
24 tools for GEDCOM 5.5, 5.5.1 and 7.0, one tool per page. Load a file once and every tool reads it, and a file you write back comes out byte for byte the same. What that guarantees.
Browser tools parse your file on your device. The optional private vault retains uploads for remote checks and reports. Model-assisted tools send the text you approve and describe it before sending.
