How do I open a GEDCOM file?
The fastest way is to drop the .ged file into a free online GEDCOM viewer, which renders it as a family tree in your browser with nothing to install. You can also import it into family-tree software like Gramps, RootsMagic, Ancestry, or MyHeritage — but for a quick look, the browser viewer is instant and private.
Open your .ged file right now in our free GEDCOM viewer — drag the file onto the page and it becomes a pan-and-zoom family tree. The file is parsed entirely in your browser, so your family data never leaves your device and nothing is uploaded to a server.
What is a GEDCOM file?
GEDCOM (GEnealogical Data COMmunication, extension .ged) is the universal file format for exchanging family trees between programs. It's a plain-text file that stores individuals, families, dates, places, and the links between them, so a tree built in one app can be opened in almost any other.
Because it's plain text, a .ged file will open in any text editor — but you'll see raw tags like “0 @I1@ INDI” and “1 BIRT” rather than a readable tree. A viewer's job is to turn that structure back into names, dates, and a chart you can actually follow.
The format has gone through a few versions — 5.5 and 5.5.1 are the long-standing standards, and 7.0 is the modern revision — but the vast majority of tools read them all. A .ged file almost always arrives one of two ways: you exported it from a genealogy site or program, or a relative sent you theirs to look at. Either way, the file is self-contained: everything needed to display the tree is inside it.
How do I export a GEDCOM file to open elsewhere?
Most genealogy platforms and programs can export your tree as a GEDCOM so you can open it somewhere else. Look for an “Export,” “Download,” or “Backup” option, usually in tree settings or the file menu, and choose GEDCOM (.ged). The exact wording varies by site, but nearly every serious tool offers it.
Exporting is what makes a GEDCOM valuable: it's your escape hatch from any one platform. Once you have the .ged, you own a portable copy of your tree that you can open in the free GEDCOM viewer, move into another program, or import somewhere new — without being locked into the site you built it on.
The exact steps differ per platform, and so does what the export quietly leaves behind. We have written one guide each: export a tree from Ancestry (the file arrives zipped, and photos stay put), export a tree from MyHeritage (two routes, and the photo option does less than it sounds like), and export a tree from FamilySearch (eight generations only, and its own help pages still say it is impossible).
How do I open a .ged file for free, right now?
Use a browser-based viewer — no download, no account, no upload. Open the tool, drag your .ged file onto it, and it renders your tree instantly. Because everything runs locally in the page, it's both the quickest and the most private way to open a GEDCOM you've been sent or exported.
- Open the free GEDCOM viewer.
- Drag your .ged file onto the page (or click to choose it).
- Explore the tree: pan, zoom, and click any person to re-center.
Want a health check instead? Run it through the GEDCOM validator. Want it as a spreadsheet? The GEDCOM converter turns the same file into CSV, JSON, or one trimmed branch, and GEDCOM to Excel walks through the spreadsheet end of it.
How do I open a GEDCOM on Windows, Mac, or my phone?
The same way on all of them: a GEDCOM is just text, so any modern browser on any device can open it through an online viewer — no platform-specific app required. On a phone or tablet where installing desktop genealogy software isn't an option, a browser viewer is usually the only practical way to see the tree.
If you double-click a .ged file, your operating system may not know what to open it with, or may open it in a text editor showing raw codes. That's expected — the extension isn't registered to a tree viewer by default. Opening it through the browser viewer sidesteps the whole file-association problem.
Which programs open GEDCOM files?
Almost every genealogy program imports GEDCOM. Free options include Gramps (open-source) and the online viewer above; paid desktop apps include RootsMagic, Legacy Family Tree, and Family Historian; and the big web platforms — Ancestry, MyHeritage, and FamilySearch — all import a .ged to bring an existing tree in.
| Program | Cost | Best for |
|---|---|---|
| Online GEDCOM viewer | Free | A quick, private look with nothing to install |
| Gramps | Free / open-source | A full desktop tree without a subscription |
| RootsMagic, Legacy, Family Historian | Paid desktop | Long-term tree management offline |
| Ancestry, MyHeritage, FamilySearch | Web (free–paid) | Importing a tree to search records online |
Which one you reach for depends on the goal. If you just need to see what's in a file someone sent you, the online viewer is the right tool — instant and private. If you want to keep and grow the tree, pick a program you'll stick with, since re-importing a GEDCOM between apps can lose some formatting and custom fields. And if the point is to find who's missing, an AI research assistant that imports your .ged and searches records for you is a different kind of help entirely.
My GEDCOM won't open or the characters look garbled — what now?
Garbled letters (odd symbols where accents should be) almost always mean a character-encoding mismatch — older files use ANSEL while newer ones use UTF-8. A file that won't open at all is usually truncated, wrongly renamed, or structurally broken. A validator pinpoints the problem instead of leaving you guessing.
Run the file through the free GEDCOM validator: it reports encoding issues, impossible dates, broken references, and duplicate people as a tree-health score. A viewer that handles ANSEL and UTF-8 — like ours — will also display accented names correctly where a plain text editor mangles them.
- Garbled accents (é shows as a symbol) → an encoding mismatch; open it in an ANSEL- and UTF-8-aware viewer.
- Nothing opens or the file is tiny → the export was interrupted or truncated; re-export it from the source.
- The file has a .txt or .ged.txt name → rename it to end in .ged, or just drag it into the browser viewer, which reads the contents regardless of extension.
What can I do with a GEDCOM once it's open?
Beyond viewing it, you can check its health, clean up duplicates and errors, and use it as the starting point for more research. Importing your existing .ged into AncestorIQ lets its AI research assistant look for the records and relatives your tree is still missing — so an old export becomes a living project again.
Exported a tree from another site and want to do more with it? Bring it into AncestorIQ, where you can keep building by chatting and let Deep Research search multiple archives for who's missing.
