MergeMyLibrary: the facts

In one sentence

MergeMyLibrary moves your Google Photos into OneDrive with the right dates, nothing lost and no duplicates: one tool that merges your clouds, then tidies them.

The name is one word: MergeMyLibrary. Website: mergemylibrary.com.

Where does it stand today?

How will it work?

1. Ask Google for a copy of your photos.

   You use Google Takeout (Google's own download tool) and send the copy to your Google Drive.

2. See your free report.

   Sign in with your Microsoft account. Then a window from Google opens, and you tick your copy. A quick estimate shows roughly how many of your photos OneDrive already has. Nothing is copied or changed.

3. Pay once, then press Merge.

   It copies only what OneDrive is missing into a "From Google Photos" folder inside your Pictures folder, sorted by year and month, and checks every copy.

Nothing to install. It runs in your web browser and on our computers.

What will it do?

• Copies only what's missing. It compares every photo with what OneDrive already holds: first identical files, then the pictures themselves.
• Puts the right date and place on each photo, using the details Google keeps for every photo.
• Rebuilds your Google Photos albums as OneDrive albums.
• Lets you choose what happens to Google's edited copies: keep them next to the originals, put them in their own folder, or skip the ones that look the same as the original.
• Asks you when it isn't sure whether two photos are the same. If you don't answer, it copies the photo.
• Shows you it's working while it runs, and emails you when it's done.

What won't it do?

• It doesn't delete anything from Google Photos or OneDrive.
• It doesn't tidy up the duplicates already in your OneDrive yet. That's coming next, and it will ask you before anything is removed.
• It doesn't carry over the names Google gives to faces.
• It only moves photos into OneDrive. Not iCloud, Dropbox or anywhere else, for now.
• It isn't a phone app. It runs in a web browser.
• It doesn't edit photos or pick your best shots.
• It doesn't change the dates of photos already in your OneDrive. It puts dates on the photos it copies.
• A photo with no date anywhere stays undated.

Is it safe?

Five rules that don't bend:

1. It looks but doesn't touch until you press Merge. The free report can't change anything.
2. It only adds. Nothing is deleted from Google Photos or OneDrive.
3. Every copy is checked against the original after it's copied.
4. You get a full list, and undo for 30 days. Undo moves the photos it copied to your OneDrive recycle bin and leaves everything else alone. (OneDrive doesn't let apps delete albums, so you'd remove those by hand. The photos in them aren't touched.)
5. Your photos are never kept on our computers. They pass through on the way to OneDrive. Pictures you see on screen are fetched when needed and never saved.

What can it see in my accounts?

• Microsoft: you sign in with your Microsoft account, and Microsoft asks your permission for MergeMyLibrary to see the files in your OneDrive and, when you merge, to add files. It uses that to list what's already there (names, sizes, dates and a fingerprint Microsoft keeps for each file) and to add the missing photos. The only files it ever opens are photos and videos. It never opens, copies or changes your documents.
• Google: only the files you tick in Google's own window. Nothing else in your Google account.

What will it cost?

Planned launch prices, in US dollars. Not on sale yet. Not sure how big your Google copy is? The free report tells you, before you pay.

• One-off payments. No subscription.
• US prices don't include sales tax.
• Every Merge Pass includes the merge, your albums, 30 days of undo and, when it's ready, the OneDrive tidy-up.
• Refunds: a full refund if your merge doesn't finish, or within 14 days if you haven't started a merge.
