Here is the trap. Your iPhone says storage is full, so you want to move your photos to Google Photos to free up space. But the usual advice, install the Google Photos app and let it back up, needs those photos sitting on the phone first. With no room to download them, you are stuck in a loop. There is a way out, and it does not touch your phone’s storage at all.
Apple quietly built a tool that copies your iCloud photo library straight to Google Photos, server to server, without ever loading a single image onto your device. It is the right answer for a full phone, and most people have never heard of it. Here is exactly how to use it, what it leaves behind, and how to actually reclaim your space afterward.
The Short Answer
Go to privacy.apple.com on any browser, sign in, and choose “Transfer a copy of your data.” Pick photos and videos, sign in to your Google account, and confirm. Apple copies everything from iCloud to Google Photos directly, which takes three to seven days and uses zero space on your iPhone. Your originals stay in iCloud until you delete them yourself.
Why a Full iPhone Changes the Plan
Most guides tell you to install Google Photos, turn on backup, and wait. That works fine when your phone has space. It falls apart when it does not.
If you use “Optimize iPhone Storage,” and most people with a full phone do, your device only keeps small previews. The full-resolution originals sit in iCloud. For the Google Photos app to back those up, it first has to pull each original down to the phone, which is the exact space you do not have. You end up freeing nothing and fighting a spinning wheel.
Apple’s transfer tool sidesteps the whole problem. It hands your library from iCloud’s servers to Google’s servers directly. Your phone is not part of the pipe, so its storage never fills. That single detail is why this method wins for anyone whose device is already jammed.
The Best Method: Apple’s Direct Transfer Tool
You can run this from a phone browser or a computer. A computer is easier because you will be signing into two accounts.
- Open Apple’s Data and Privacy page at privacy.apple.com and sign in with your Apple Account.
- Choose Transfer a copy of your data. If you do not see it, confirm you have iCloud Photos turned on, since the option only appears when there is a library to move.
- Select Photos and videos as the content to transfer.
- Sign in to the Google account you want the photos to land in, and grant Google Photos permission to receive them.
- Review the summary, which shows roughly how many items and how much data will move, then confirm the request.
- Wait. Apple emails you when the transfer starts and again when it finishes, usually within three to seven days.
Nothing on your iPhone changes during this window. You can keep using it normally. The copy runs entirely in the cloud.
Before You Start: Check Your Google Storage
The transfer lands in the same 15 GB that Google shares across Gmail, Drive, and Photos. If your iCloud library is larger than the free space in your Google account, the transfer will stop partway and skip whatever did not fit.
Check your library size in Settings, then tap your name, iCloud, to see how many gigabytes your photos use. If it is more than your free Google space, upgrade to Google One before you begin. The current plans are 100 GB for $1.99 a month, 200 GB for $2.99, and 2 TB for $9.99. Pick a tier with headroom, because a library that barely fits today will overflow the next time you shoot a few videos.
What Will Not Come Across
The tool copies the bulk of your library, but a few things get left behind because Google Photos handles them differently. Apple lists these clearly, and it is worth knowing before you rely on the copy.
- Live Photos lose their motion. You keep the still frame, not the short clip.
- Shared albums and Smart Albums do not transfer at all, nor does older My Photo Stream content.
- Some RAW files are skipped, since Google Photos does not support every format.
- Videos arrive without their albums. Photos keep album groupings where possible, but videos land loose in the main library.
- Some metadata may not carry over exactly, so double-check dates on anything important.
None of this deletes the originals in iCloud. If you have shared albums or Live Photos you care about, keep them in iCloud or export them separately before you cut ties with Apple.
After the Transfer: Reclaiming Your Space
This is the step people forget. The transfer is a copy, not a move, so your iPhone is exactly as full as it was. Freeing space is a separate job you do only after you have confirmed the copy landed safely in Google Photos.
Open Google Photos, spot-check a range of dates, and make sure your important memories are actually there. Once you trust the copy, you have two options. To stay in Apple’s ecosystem but reclaim iCloud space, delete the photos you no longer need from the Photos app, which clears them from iCloud after 30 days in Recently Deleted. To leave iCloud Photos entirely, turn it off in Settings under your name, iCloud, Photos, and choose to download or remove the local copies. Move slowly here, and never delete from iCloud until Google Photos has a verified copy.
What To Know
- Apple’s privacy.apple.com transfer tool copies iCloud Photos to Google Photos server to server, using no iPhone storage.
- The Google Photos app method fails on a full phone because it has to download originals first.
- Transfers take three to seven days, and Apple emails you at the start and finish.
- Your Google account needs enough free space, so upgrade to Google One first if your library is large.
- Live Photos, shared albums, Smart Albums, and some RAW files do not transfer, and the copy never deletes your iCloud originals.
Frequently Asked Questions
How do I move iCloud Photos to Google Photos when my iPhone is full?
Use Apple’s transfer tool at privacy.apple.com instead of the Google Photos app. Choose “Transfer a copy of your data,” select photos and videos, and sign in to Google. Apple copies your library from iCloud straight to Google Photos without downloading anything to your phone, so a full device is not a problem.
Does transferring to Google Photos delete my iCloud photos?
No. The tool only makes a copy. Every photo and video stays in iCloud until you delete it yourself. That is a safety feature, since it lets you verify the copy in Google Photos before you free up any space.
How long does the iCloud to Google Photos transfer take?
Apple says three to seven days for most libraries, and larger collections can take longer. You get an email when the transfer begins and another when it is done. Your iPhone works normally the entire time because the copy happens in the cloud.
Will I need to pay for Google storage?
Possibly. Google gives every account 15 GB free, shared across Gmail, Drive, and Photos. If your iCloud library is bigger than your free space, upgrade to Google One first. Plans start at $1.99 a month for 100 GB, with 200 GB at $2.99 and 2 TB at $9.99.
What does not transfer from iCloud to Google Photos?
Live Photos lose their motion and keep only the still image. Shared albums, Smart Albums, My Photo Stream content, and some RAW files are skipped entirely. Videos transfer without their album groupings, and a little metadata may not carry over, so check dates on anything important.
What To Do Next
Start by checking your library size in Settings, then open privacy.apple.com and request the transfer today, since it runs on its own for several days. While you wait, size up your Google storage and upgrade if needed so nothing gets skipped. Once the copy is verified in Google Photos, then and only then, clear space on your iPhone.
