How to Back Up Your Photos Before You Delete Anything

I write guides about clearing storage, and I build an app that deletes photos. Both of those make this the article I should have published first. Everything else on this site is safe to act on once you have done this; without it, every cleanup is one mis-tap away from being permanent.

Why iCloud is not a backup

This is the single most expensive misunderstanding in consumer tech, and the naming is largely to blame. People say "it's backed up to iCloud" when what they mean is "it's synced to iCloud," and those behave in opposite ways at the only moment that matters.

Apple is explicit about the mechanism: *"If you use iCloud Photos, and delete photos and videos from one device, the photos and videos will be deleted on your other devices."* And once you empty Recently Deleted, *"you can't get it back."*

So the Mac copy is not a safety net, because it is the same library. Neither is the iPad. The thing people believe is their backup is usually a second window onto the one copy they have.

Step zero: make sure iCloud has the originals before you export

Skip this and you can spend an hour exporting placeholder files. It is the most common way a backup silently fails.

If Optimize iPhone Storage is on, your phone holds smaller device-sized versions and the full-resolution originals live in iCloud. Export from the phone in that state and you may get the small versions. Worse, if some photos never finished uploading, the originals may not be anywhere.

1. 01

   Check the upload actually completed

   Open Photos and scroll to the very bottom of your Library. If there is a status line saying items are still uploading, or a paused message, let it finish before you do anything else. On a big library over a slow connection this can take days, not minutes.

2. 02

   Push it along if it has stalled

   On iOS 27 and later there is a Sync Immediately toggle in Settings → [your name] → iCloud → Photos that forces pending uploads through rather than waiting for the system to pick its moment. Plug in, get on Wi-Fi, and turn it on.

3. 03

   Decide where you are exporting from

   If iCloud has everything, exporting from iCloud.com or a Mac set to keep originals gives you true full-resolution files. If you would rather export from the phone, switch to Download and Keep Originals first and wait for the download to finish — otherwise you are copying thumbnails.

Pick one method — any of these is vastly better than none

Perfect is the enemy of done here. A single external drive you update twice a year beats an elegant three-tier plan you never set up.

Option A — Export to a computer or external drive

The strongest option, because the copy is entirely yours and depends on no company, subscription or account.

• On a Mac: open Photos, select everything (Cmd-A in the Library view), then File → Export → Export Unmodified Original. "Unmodified Original" is the one you want — the other option re-encodes. Choose subfolder-by-moment and filename options so you get a navigable folder tree rather than 40,000 loose files.
• On a Mac, without the Photos app: plug the iPhone in and use Image Capture, which copies straight off the device with no library involved. Simple and fast, though it exports in device order rather than albums.
• On Windows: plug the iPhone in, unlock it, tap Trust, then open File Explorer → Apple iPhone → Internal Storage → DCIM and copy the folders. Alternatively install iCloud for Windows and let it download the library to a folder.
• From anywhere: sign in at iCloud.com → Photos, select, and download. Fine for a few hundred items; painful for tens of thousands, as it zips in batches.

Option B — A second cloud service

Less robust than a drive you own, but far easier to keep current, because it runs by itself once configured. The key property is that it is a *separate* service: deleting in Apple Photos does not delete there.

Google Photos is the common choice and will upload in the background from the iPhone app. Amazon Photos is included with Prime and offers full-resolution photo storage. Dropbox and OneDrive both do camera upload. If you would rather the contents were end-to-end encrypted, Ente and Proton Drive are built for that.

I am not ranking these, because the right answer depends on what you already pay for. What matters is that it is not Apple.

Option C — Both, if the library is irreplaceable

If this library contains the only pictures of someone who has died, a wedding, a childhood — the standard advice applies: more than one copy, in more than one place, and at least one of them offline. A drive in a drawer plus a cloud service covers fire, theft, account loss and your own mistakes simultaneously.

Verify it — the step everyone skips

An unverified backup is a belief, not a backup. Most people discover a failed export at the exact moment they need it. Four checks, five minutes:

1. 01

   Compare the counts

   Photos tells you your library total at the bottom of the Library view. Your export folder should contain a comparable number of files. If the phone says 23,000 and the folder has 9,000, the export stopped early — a very common outcome on large exports.

2. 02

   Open a dozen at random

   Not the first twelve, which are the most likely to have worked. Pick some from the middle and from years ago. They should open full-screen and look sharp.

3. 03

   Check the file sizes

   Sort the folder by size. Photos of a few hundred kilobytes where you expected two to three megabytes mean you exported optimised versions rather than originals — go back to step zero. Any 0 KB files are failed copies.

4. 04

   Spot-check your oldest and largest items

   The oldest photos and the longest videos are the ones most likely to have been optimised away or to have failed mid-transfer. If those are intact, the rest probably is too.

Traps worth knowing about

• Live Photos export as two files — a still plus a short video. Some destinations keep only the still, and the motion is gone. Not a disaster, but know it is happening.
• HEIC conversion. iPhones shoot HEIC. Some exports convert to JPEG, which re-encodes and loses a little quality. "Export Unmodified Original" on a Mac avoids this.
• Albums and favourites usually do not survive. You are backing up files, not your organisation. If your album structure matters, a Mac Photos library copied wholesale preserves it; a folder of exported files does not.
• Edits may export as the edited version only, or the original only, depending on the option chosen. If you have heavily edited shots you care about, test with a handful first.
• Shared Library and shared album items may not be yours to export in full, and may be excluded from your library export entirely.
• Some services strip EXIF metadata, including the date and location. A backup where every photo is dated today is a poor archive even if the pixels survived.

Then, and only then, start deleting

With a verified copy in hand, everything changes. A mis-swipe is an inconvenience rather than a loss, bulk deletion stops being frightening, and you can be properly ruthless with the eleven near-identical shots of one moment — which is where the real space is.

This is also the honest prerequisite for using any cleanup app, mine included. Those tools make deleting fast, and fast deleting without a backup is just a faster way to lose something. Any app that encourages bulk deletion without mentioning this is not being straight with you.

Once you are covered, the five biggest storage wasters is where the gigabytes actually are.
