These three services do broadly the same job, get photos off your phone, back them up, make them searchable, but they differ in ways that matter a lot depending on what devices you own and what you're trying to protect against.
Here's the comparison, followed by the thing all three articles like this usually skip: none of these is a backup, and the difference could cost you your library.
The short version
Google Photos has the best search and works identically on every device. It's the default choice for most people, especially anyone with Android or a mixed household.
Apple Photos is the smoothest experience if everything you own is Apple, and its editing and organization tools are better. It's a poor fit if anyone in your household uses Android or Windows.
Amazon Photos is essentially free unlimited photo storage if you already pay for Prime. It's the weakest product of the three, and that's fine, because the price is unbeatable for the specific job of "keep a copy of everything."
Search
This is the biggest functional difference between them.
Google Photos is genuinely excellent. Search for "red bicycle," "receipts," "Emma at the beach," "snow 2019" and it works. It reads text inside images, so you can find a photo of a business card by searching the company name. Face grouping is accurate and easy to name.
Apple Photos has closed much of the gap. Face recognition is good, object and scene recognition is solid, and text recognition works well. It's a step behind Google on complex or conceptual queries but perfectly capable for everyday finding. One meaningful difference: much of Apple's analysis happens on your device rather than on their servers, which is better for privacy and worse for speed on large libraries.
Amazon Photos does basic object and face recognition. It works, but noticeably less well. Treat search here as a bonus rather than a feature you'll rely on.
Storage and cost
Google Photos shares a single storage pool with Gmail and Google Drive, which trips people up constantly — a full mailbox stops your photos from backing up. Free tier is 15 GB across all three services, which fills fast. Paid tiers scale up from there at competitive rates.
Apple Photos uses iCloud storage, also shared with backups, mail, and documents. The free tier is 5 GB, which is not enough for anyone and is widely considered stingy. Paid tiers are reasonably priced and can be shared across a family group.
Amazon Photos is the outlier: unlimited full-resolution photo storage for Prime members, plus a small video allowance. If you already pay for Prime, this is free storage for an unlimited number of photos, which no one else offers. Video is limited, so it's a photo solution rather than a complete one.
Because pricing changes regularly, check current rates before committing — but the structural difference holds: Amazon is cheapest for photo volume, Google and Apple charge for a pooled allowance that other services also eat into.
Device fit
This matters more than any feature.
All Apple household: Apple Photos is the obvious pick. It's built into every device, sync is invisible, and the integration with Messages, Memories, and shared albums is seamless.
All Android, or Android + Windows: Google Photos. Apple Photos on Windows exists but is limited, and there's no Android app at all.
Mixed household: Google Photos. This is the most common real situation — an iPhone user married to an Android user, kids with whatever they got handed down. Google works the same everywhere. Apple's ecosystem advantage becomes an ecosystem trap the moment one person is outside it.
Anyone with Prime: Amazon Photos alongside whichever primary service you chose. Since it's free and unlimited, running it as a second automatic copy is close to a free win.
Sharing
Google Photos has the most flexible sharing: shared albums anyone can view without an account, a partner-sharing feature that automatically shares photos of specific people with your spouse, and link sharing that just works.
Apple Photos has Shared Albums and a Shared Library that automatically pools photos with family members. Excellent within Apple; awkward outside it — non-Apple recipients get a web view that's noticeably worse.
Amazon Photos has a Family Vault where up to five people can contribute to a shared space, and each gets their own unlimited photo storage under the Prime subscription. Underrated feature, genuinely useful for extended family archives.
Getting your photos back out
This is the section that should carry more weight than it usually does. Ease of export determines whether you're a customer or a hostage.
Google Photos offers Google Takeout, which exports your full library. It works, but it's clunky: large libraries arrive as many ZIP files, and metadata comes in separate JSON files alongside the images rather than embedded. Reassembling that into a clean library takes real effort. It's a genuine export path, just an unpleasant one.
Apple Photos exports cleanly from the Mac app — select everything, File → Export, choose whether to keep the original files with metadata intact. This is the best export experience of the three. From iCloud.com or from Windows it's much more awkward.
Amazon Photos allows downloads through the web interface and desktop app. Fine for moderate volumes, tedious for tens of thousands of files.
The test worth applying to any service: if you stopped paying tomorrow, how hard would it be to leave with everything intact? All three pass, but none is effortless, and that's precisely why you shouldn't let any of them be your only copy.
The thing all three have in common
None of these is a backup. They're sync services.
If you delete a photo on your phone, it deletes everywhere. If a file corrupts, the corruption syncs. If your account is locked, suspended, or lost, everything goes with it. All three have a trash retention window — typically 30 to 60 days — which helps with simple accidents and does nothing for the bigger failure modes.
Account loss is the underrated risk. It's rare, but recovering a locked Google or Apple account with no other access is genuinely difficult, and there is no customer service line that reliably solves it. People do lose entire photo libraries this way.
The fix is straightforward: twice a year, export from whichever service you use into a photo library you control on a drive at home. Then back that up. The cloud service becomes what it's good at — convenient access and search — rather than the only thing standing between you and losing everything.
Which to choose
Choose Google Photos if: you have Android, a mixed-device household, or you want the best search. This is the default answer for most people.
Choose Apple Photos if: every device in your house has an Apple logo, and you want the smoothest experience with the best editing tools.
Add Amazon Photos if: you have Prime. Unlimited free photo storage as a secondary automatic copy is worth the ten minutes of setup regardless of what else you use.
Use two of them. This is the underrated move. Nothing stops you from running Google Photos and Amazon Photos simultaneously, both backing up automatically. Two independent copies in two different companies' infrastructure, for the cost of a Prime membership you already have.
Setting it up well
Whatever you choose:
Verify it's actually running. Take a photo now, then check that it appears in the web interface within a few minutes. Silent sync failure is extremely common — a full storage quota, a paused upload, a setting that reverted after an update. People discover it years later.
Turn off the option to delete local copies until you've confirmed the upload. Both Google and Apple offer to free up phone space by removing local files. That's fine once you trust the sync, dangerous before.
Check your storage quota every few months. When you hit the limit, backups stop. On Google this often happens because Gmail filled the shared pool, with nothing obviously wrong on the photos side.
Don't run Google Photos and Apple Photos on the same iPhone without understanding what happens. Both will try to manage your library, deletions can behave unexpectedly, and you'll generate duplicates. Pick one as primary; if you want a second copy, Amazon Photos is the more cooperative choice.
