How it works

Three steps. No upload, no signup.

  1. 1

    Drop your file

    Click the dropzone above or drag a GEDCOM from your desktop. Files of any size, there's no upload, so there's no upload limit.

  2. 2

    Convert in your browser

    The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.

  3. 3

    Download

    Get your PDF the moment the conversion finishes. Convert another, or close the tab.

Files stay on your device

Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.

No file size limit

Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.

Free, no signup, no ads on conversions

No account required. No watermark on the output. No queue. Open source, every line of conversion code is public.

About GEDCOM and PDF

GEDCOM, Genealogical Data Communication

GEDCOM is the universal interchange format for family-tree data. The current spec is GEDCOM 7.0 (2021) but most genealogy software still emits GEDCOM 5.5.1 (2019) for compatibility. Plain-text hierarchical records: 0-level lines define individuals (INDI) and families (FAM); deeper levels (1, 2, 3...) attach attributes like names, dates, and places. Every major genealogy app reads and writes GEDCOM.

How to open

Ancestry, MyHeritage, FamilySearch, RootsMagic, Family Tree Maker, Gramps, MacFamilyTree. Plain text in any editor.

PDF, Portable Document Format

PDF is the universal document format for fixed-layout content, invoices, contracts, scanned documents, e-books, forms. Created by Adobe in 1993 and made an open ISO standard in 2008, PDF preserves exact layout, fonts, and images across every device. Files can be searchable text, scanned images, or both. Most modern PDFs include a text layer that copy/paste and search work against.

How to open

Every modern browser opens PDFs natively. Acrobat Reader is free; macOS Preview, Windows Edge, and ChromeOS all open PDFs without extra software. For editing, Adobe Acrobat Pro or open-source PDFsam are common.

FAQ

Common questions

Is this GEDCOM → PDF converter really free?

Yes. No signup, no watermark, no daily file count limit. The entire engine is open source, you can read the conversion code on GitHub.

Where does my file go when I convert it?

Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.

What's the maximum file size?

Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.

Why convert GEDCOM to PDF?

Family tree interchange between genealogy programs. Documents that need to look identical on every device. The most common reason to convert is compatibility, PDF works in places where GEDCOM doesn't, or vice versa.

How do I open a GEDCOM file in the first place?

Ancestry, MyHeritage, FamilySearch, RootsMagic, Family Tree Maker, Gramps, MacFamilyTree. Plain text in any editor.

Does this work offline?

Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.

Can I convert multiple files at once?

Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
