Your research belongs to you. Every major genealogy service can hand it back as a GEDCOM (.ged) file — these guides show the exact route through each one's menus, what the file includes, and what stays behind.
Tree Settings → Export Tree → Download. Owner-only, and photos stay behind — here's the full picture.
1 SOUR MyHeritageFamily tree → Manage trees → Export to GEDCOM, free on every plan.
1 SOUR FamilySearchThe new official 8-generation export from the shared Family Tree — plus the certified-app route for fuller branches.
1 SOUR FTMFile → Export, with the character-set choice that keeps accented names intact.
A .ged file is plain text — open it in Notepad and you'll see names between slashes and cryptic tags. To actually read it, drop it into the free viewer. To hand it to relatives, convert it to a printable PDF or a one-file web page. And before importing it into new software, the validator will tell you if anything in the file would trip the import up.
