iCloud to Google Photos transfer: avoid and clear duplicates

Updated November 7, 2026 · 7 min read

Apple's transfer service copies your iCloud Photos library to Google Photos, and Apple says duplicates inside your iCloud library arrive as just one photo. Doubles can still turn up in Google Photos from three other places: photos your phone already backed up to Google Photos, edited versions arriving next to originals that are already there, and a second transfer or a top-up by hand. The safest order is to clean iCloud Photos first, so you move less and need less Google storage. Then run the transfer. When Apple's email says it has finished, clear any doubles in Google Photos. Removed photos wait in the Google Photos trash for 30 days, so nothing is final until the trash is emptied.

How Apple's transfer works

Apple's help page on the transfer (published 9 October 2026) sets out the rules. The ones that matter for duplicates:

Where you start it. Sign in at privacy.apple.com, Apple's Data & Privacy page, and choose to transfer a copy of your data.
What you need. Your photos must be in iCloud Photos, your Apple Account needs two-factor authentication, and Advanced Data Protection must be off. Your Google account needs enough free storage for everything you send. Child accounts and Managed Apple Accounts can't use it.
How long it takes. Most transfers take three to seven days. Some take up to 30.
It's a copy. Nothing in iCloud is removed or changed.
Edits. Only the most recent edit of each photo is transferred, not the original.
Albums and videos. Photos arrive in their albums where possible. Videos come across separately, without albums. Album names and video file names start with "Copy of".
What doesn't transfer. Apple lists shared albums, smart albums, Live Photos and some metadata among the things that aren't transferred.
Big albums. A Google Photos album holds up to 20,000 photos. Extra photos still transfer but aren't added to the album.
Changes along the way. Anything you add, change or delete after the transfer starts might not be included. If you cancel, the photos that already arrived stay in Google Photos.

Where the doubles come from

1. Your phone already backed up to Google Photos

If the Google Photos app on your iPhone has been backing up, many of your photos are already in Google Photos. Apple's note about duplicates is about copies inside your iCloud library. It doesn't mention photos that are already in Google Photos, so the transfer can put a second copy next to the one your phone uploaded.

2. Edited photos

Only the most recent edit is transferred. If Google Photos already has the original from a phone backup, you can end up with the original and the edited version side by side. They aren't exact copies, so you'll want to choose which one to keep.

3. A second transfer, or topping up by hand

Apple doesn't say what a new request does with photos that already arrived. And because changes made during a transfer might not be included, you may end up uploading a few missing photos yourself afterwards. Either way, check for doubles once you're done.

4. The lookalikes you already had

Similar shots and burst frames are different photos, not copies, so they all transfer and all use Google storage. If you were never going to keep ten frames of the same moment, it's cheaper to choose the best one before they move.

Before you transfer: clean iCloud Photos first

Cleaning first means fewer photos to move, less Google storage used, and one clean-up instead of two.

Merge the exact copies with Apple's free tool. On an iPhone, open Photos, tap Collections, scroll to Utilities and tap Duplicates, then merge the sets. On a Mac, Duplicates is under Utilities in the Photos sidebar. Merged extras go to Recently Deleted for 30 days.
Deal with the lookalikes and bursts. Apple's Duplicates album looks for copies of the same image, so it won't pick the best of ten similar frames. Doppelgone does: it works on iCloud Photos in Chrome at icloud.com, in the iPhone app, and in the Mac app through the Photos library. It finds exact copies, lookalikes and burst shots, keeps the best shot of each set and says why. You approve every clean-up, and removed photos wait in Recently Deleted for 30 days. More in find similar and burst photos in iCloud Photos.
Check your Google storage. Google's free storage is shared by Gmail, Drive and Google Photos. If it's nearly full, the transfer can stop short. See Google One 15 GB full.
Look in Google Photos first. If the Google Photos app on your iPhone has been backing up for years, your older photos may already be there, and a full transfer would add them again. You may only need the transfer for photos that never went through the Google Photos app.

After the transfer: clear the doubles in Google Photos

Wait for Apple's email. Apple emails you when you make the request and again when the transfer is complete. Clean up after the second email, so you're not working on a library that's still filling up.
Scan Google Photos. In Chrome on a computer, add Doppelgone, open photos.google.com and start a scan. It groups exact copies, lookalikes (which can include an original and its edited copy) and burst shots.
Review the sets. In each set Doppelgone keeps the best shot, the one with eyes open, sharp and well lit, and shows why it chose it. Tap any other photo to keep that one too.
Approve the clean-up. Removed photos go to the Google Photos trash for 30 days, and there's a one-click undo. Favourites, videos and photos shared with you are never touched.
Check videos by hand. Doppelgone doesn't touch videos. Transferred videos have file names that start with "Copy of", which helps you tell them apart from videos your phone uploaded.
Get the space back. Photos in the Google Photos trash still count toward your storage. Empty the trash once you're happy, or let Google empty it after 30 days. See Google Photos trash explained.
Decide about iCloud last. The transfer is a copy, so your iCloud library is untouched. If you're leaving iCloud, check that everything you care about arrived before you change anything there.

If you only have a few doubles, you can also do it by hand: open a month you know overlaps, compare the copies and move the extras to the trash. The steps are in how to delete duplicate photos in Google Photos.

Frequently asked questions

Does Apple's transfer to Google Photos create duplicates?

Apple says duplicates inside your iCloud library arrive as just one photo. Doubles can still appear in Google Photos when your phone already backed up the same photos there, when an edited version arrives next to the original, or after a second transfer or a top-up by hand.

Will the transfer delete my photos from iCloud?

No. Apple says the transfer sends a copy and doesn't remove or change anything you store with Apple.

How long does the transfer take?

Apple says most transfers take three to seven days, and some take up to 30 days. You get one email when you make the request and another when it's finished.

What doesn't transfer?

Apple lists shared albums, smart albums, Live Photos and some metadata among the things that aren't transferred, and only the most recent edit of each photo goes across. Keep your iCloud library until you've checked that everything you care about arrived.

Should I clean up before or after the transfer?

Both, if you can. Cleaning iCloud Photos first means fewer photos to move and less Google storage used. Checking Google Photos afterwards catches doubles from earlier phone backups, edited versions and top-ups.

Can Doppelgone remove duplicate videos after the transfer?

No. Doppelgone never touches videos, so check video doubles by hand. Transferred videos have file names that start with "Copy of", which makes them easier to spot.

What about moving from Google Photos to iCloud Photos?

That transfer starts in Google Takeout, and Apple says a later request won't add duplicate photo or video files to iCloud Photos. Apple's page doesn't say whether it skips photos that are already in iCloud from your iPhone, so check the Duplicates album afterwards.

What to do next

Before you start the transfer, run a free scan of your iCloud Photos library to see how much of it is doubles, in Chrome at icloud.com or with the iPhone app. After the transfer, run the same scan on photos.google.com. Nothing moves until you approve it, the free plan covers 200 clean-ups, and Pro is one payment of $9.99 if you need more.
