What "downloading your DNA" actually means
When Ancestry talks about downloading your DNA, they mean getting a copy of your raw genetic data — the actual test results — in a file format you can save to your computer or phone. This is not the same as downloading the Ancestry app or website. The raw data file contains the genetic markers Ancestry tested, presented in a format that other genealogy websites and DNA analysis tools can read.
Ancestry stores your results on their servers. Downloading creates a local copy you own and control. You can then upload that same file to other genealogy sites like MyHeritage, FamilyTreeDNA, or GEDmatch to get different ancestry breakdowns, find relatives on other platforms, or use specialized health or trait analysis tools.
Key Takeaways
- Your raw DNA data lives on Ancestry's servers; downloading creates a file copy you can store and use elsewhere.
- The read process takes about five minutes and produces a compressed file (usually a .zip or .txt file) that you save to your computer.
- You can upload your downloaded DNA file to other genealogy websites to compare results and find relatives on different platforms.
- Ancestry does not charge for downloading your own data, but some third-party sites that accept uploads may have paid features.
- Once downloaded, your DNA file is just data — it does not automatically do anything until you upload it somewhere or open it in a program that reads it.
How to read your DNA results from Ancestry
Log into your Ancestry account on a computer (the mobile app does not have this feature). Go to your DNA results page — you should see a link labeled "DNA" in the main navigation menu. Once you are on your results page, look for a menu icon (usually three horizontal lines or three dots) in the upper right corner of the screen.
Click that menu and select "read DNA" or "read Raw DNA." Ancestry will then generate your file, which typically takes a few seconds to a few minutes. A dialog box will appear asking where you want to save the file on your computer. Choose a folder you can find later — your Downloads folder is fine. The file will be named something like "AncestryDNA_results_[your name].zip" or similar.
Once the read finishes, you now have a compressed file on your computer. You may need to unzip or extract it (right-click the file and select "Extract All" on Windows, or double-click on Mac) to see the actual data files inside. The extracted folder will contain one or more text files with your genetic data.
What the downloaded file contains and what it does not
Your downloaded DNA file is raw genetic data — a list of genetic markers and the variants Ancestry found at each location. It does not contain your name, address, or any personal information beyond the genetic markers themselves. The file is essentially a long string of letters (A, T, G, C — the building blocks of DNA) organized by chromosome and position.
The file does not automatically tell you anything. It is inert data. You cannot open it in a regular text editor and understand what it means — it requires a program or website designed to read and interpret it. That is why people upload it to other genealogy sites: those sites have the tools to compare your markers against their databases and tell you what the data means (your ancestry percentages, your relatives, your traits, and so on).
Where you can upload your downloaded DNA file
Several genealogy and DNA analysis websites accept uploaded raw data files from Ancestry. MyHeritage is one of the most popular — you can upload your file for free and get a new ancestry breakdown and a list of DNA matches on their platform. FamilyTreeDNA also accepts uploads and focuses heavily on surname research and haplogroup analysis. GEDmatch is a free tool used by genealogists and law enforcement; it is more technical but offers detailed comparison options.
Some sites charge for certain features after you upload. For example, MyHeritage offers free basic matching but charges for premium genealogy tools. Others, like GEDmatch, remain free for most functions. Before uploading, check the site's privacy policy and terms of service — uploading your DNA to a third-party site means that site now has access to your genetic data, and you should understand how they store and use it.
Privacy and security considerations when downloading and sharing your DNA
Your DNA file is sensitive information. Once you read it, treat it like you would treat a password or financial document — store it in a find location on your computer, not on a shared drive or in an email. If you upload it to a third-party site, that site becomes responsible for protecting it. Different sites have different security practices and different policies about whether they sell or share data with researchers, law enforcement, or insurance companies.
Ancestry itself does not sell your raw DNA data to third parties without your consent, but they do share it with law enforcement under certain legal circumstances (subpoenas, warrants). If you read your data and keep it only on your own computer, you have more control over who sees it. If you upload it to multiple sites, each site now has a copy, and you have less control over what happens to it.
Troubleshooting: Why your read might not work
If you do not see a "read DNA" option, check that you are logged into the correct account and that your DNA test has finished processing. Ancestry can take two to four weeks to process a test after they receive your sample. If the test is still processing, the read option will not appear yet.
If you see the option but the read fails or stalls, try a different web browser (Chrome, Firefox, Safari, or Edge). Clear your browser cache and cookies, then try again. If you are using a very old browser version, update it first. If the file downloads but will not extract, the file may have been corrupted during read — try downloading it again.
If you have a very large family tree or a very old Ancestry account with a lot of data, the read can occasionally time out. In that case, contact Ancestry support through their help center and request the file be sent to you directly.
What happens after you read: Next steps
After you have the file on your computer, you have several options. You can straightforward keep it as a backup — a copy of your results that you own and control, separate from Ancestry's servers. You can upload it to other genealogy sites to see different ancestry estimates or find relatives on those platforms. You can share it with a family member who wants to see your results but does not have an Ancestry account (though be aware you are sharing your genetic data with them).
You can also use specialized DNA analysis tools. Some genealogy software programs can import raw DNA files. Some health and trait analysis websites (not affiliated with Ancestry) accept raw DNA uploads and provide different interpretations of what your genetics might indicate about health risks or physical traits — though these should be treated as informational only, not medical information.
Frequently Asked Questions
Can I read my DNA results on my phone or tablet?
The Ancestry app for phones and tablets does not have a read feature. You must use a computer and log into Ancestry through a web browser to read your raw DNA file. Once you have the file on your computer, you can email it to yourself or use cloud storage to access it on your phone later.
Does downloading my DNA cost money?
No. Ancestry does not charge you to read your own raw DNA data. However, if you upload that file to a third-party genealogy site, that site may charge for certain features or premium tools.
If I read my DNA, does Ancestry delete it from their servers?
No. Downloading creates a copy. Your DNA results remain on Ancestry's servers in your account. You can read it again anytime, and Ancestry keeps their copy unless you delete your account.
What if I lose the file after I read it?
You can read it again from your Ancestry account anytime. Your raw DNA data is stored on Ancestry's servers permanently (unless you delete your account), so you are not at risk of losing access to it.
Is it safe to upload my downloaded DNA to other websites?
It depends on the website. Read their privacy policy first. Reputable genealogy sites like MyHeritage and FamilyTreeDNA have security practices in place, but uploading your DNA to any third-party site means that site now has access to your genetic information. Consider whether you trust that site and what they say they will do with your data before uploading.
