GEDCOM Tools
Every tool here runs entirely in your browser — your GEDCOM file is parsed on your own device and never sent to a server, stored, or logged. Start with the Upload Readiness Checker if you're preparing a file for FamilySearch; use the others to inspect, clean up, or export a file you already have.
