Best Cloud Storage for iPhone Photos: What Happens to HEIC
If you just want the short answer: iCloud Photos is the best cloud storage for iPhone photos if you live inside the Apple ecosystem and want your originals stored untouched. Google Photos is the best pick if you also use Android or Windows and want your library searchable everywhere. OneDrive makes sense if your life is in Microsoft 365, and Dropbox if you think in folders rather than in a photo library.
But there is a question almost every comparison skips, and for iPhone users it is the one that actually matters: what does each service do to your HEIC files? Since iOS 11, your iPhone shoots photos in HEIC by default. Some cloud services store that file exactly as it came out of the camera. Others recompress it, convert it, or hand you back something different from what you uploaded — and you only find out months later, when you try to open your "backup" on a Windows PC and nothing recognizes the format.
This guide compares the big four (plus Amazon Photos) specifically through that lens: which one preserves the original, which one converts on upload or download, what the free tiers really give you, and the workflow we recommend so your photos stay both safe and usable.
First, Know What You're Storing: HEIC in 30 Seconds
HEIC is the container Apple uses for HEIF images. Its selling point is efficiency: a HEIC photo takes up roughly half the space of an equivalent-quality JPEG, which matters a lot when you are paying for cloud storage by the gigabyte. Its weakness is compatibility: plenty of Windows PCs, older Android phones, and web forms still choke on it. If you want the full background, see what HEIC actually is and our breakdown of HEIC vs JPEG.
For cloud storage, this cuts both ways. Storing HEIC means your storage plan goes further. But it also means the file you download later may need converting before you can use it — so the smart setup is to store originals in the cloud and convert copies on demand, not the other way around.
iCloud Photos: Best for Staying Inside Apple
iCloud Photos is built into the iPhone's native Photos app, which makes it the lowest-friction option by far: turn it on and every photo and video syncs automatically.
What it does with HEIC: iCloud stores your photos in their original format. A HEIC shot on your iPhone is a HEIC in iCloud — no recompression, no silent conversion. When your iPhone runs low on space, the "Optimize iPhone Storage" setting keeps lightweight versions on the device and the full-resolution originals in the cloud; "Download and Keep Originals" does the opposite.
The catch for Windows users: iCloud faithfully preserving your HEIC originals means that when you pull those photos down on a PC — through iCloud for Windows or a download from iCloud.com — you often get HEIC files back. iCloud.com lets you choose between the unmodified original and a more compatible version when downloading, but if you end up with a folder of HEIC files on Windows, you can convert them to JPG in your browser without installing anything.
Free tier: 5 GB, shared with device backups, iCloud Drive, and Mail. With a photo library of any real size, that runs out almost immediately — iCloud only becomes a genuine photo backup once you move to a paid iCloud+ tier.
Google Photos: Best for Cross-Platform Libraries
Google Photos backs up your camera roll through its own iOS app and makes the library available on any browser, Android device, or smart display. Its search is the best in the business: you can find photos by what's in them without ever tagging anything.
What it does with HEIC: this depends on one setting, and it's the most important toggle in this article. In backup quality, "Original quality" stores the exact file you shot — HEIC in, HEIC out, byte for byte. "Storage saver" recompresses your photos to save space, which means the file you get back later is not the file you uploaded. If the point of cloud storage is preserving your originals, use Original quality; if you just want a viewable archive and maximum mileage from free space, Storage saver is the trade-off you're accepting — just make that choice consciously.
Free tier: 15 GB, but shared across Gmail, Google Drive, and Photos. Thanks to HEIC's small file sizes, that stretches further with iPhone photos than with JPEGs — one quiet advantage of not converting before upload.
One clarification, because people mix these up constantly: Google Photos and Google Drive are different products that handle HEIC differently. If your photos are landing in Drive — via shared folders, WhatsApp exports, or manual uploads — read our dedicated guide to opening HEIC files in Google Drive instead; this post won't repeat it.
OneDrive: Best If Your PC Is the Destination
OneDrive's iOS app has a camera upload feature, and if you already pay for Microsoft 365, you likely have 1 TB of storage sitting there unused — which changes the math completely.
What it does with HEIC: OneDrive can store and display HEIC files, and its camera upload settings control how photos leave your iPhone. Check those settings after installing: they determine whether your photos upload in their original format or in a more compatible one, and the right answer depends on whether you value originals (keep HEIC) or frictionless opening on any PC (convert). On the Windows side, HEIC files synced through OneDrive open in the Photos app only if the system has HEIC support — our guide to the HEIC codec on Windows 10 covers exactly how to sort that out.
Free tier: 5 GB. Like iCloud's, it's a trial-sized allocation; OneDrive only makes sense as a photo home if you're on Microsoft 365 anyway.
Dropbox: Best for Folder-Based Control
Dropbox treats your photos as files in folders, not as a photo library. For some people that's exactly the point: no algorithmic albums, no "memories," just a directory tree you control that syncs to every machine you own.
What it does with HEIC: Dropbox's camera uploads settings include an option that controls whether HEIC photos are saved as HEIC or converted to JPG on the way up. That makes Dropbox unusual: it's the service that most explicitly puts the convert-or-preserve decision in your hands at upload time. Choose HEIC to preserve originals and save space; choose JPG if the folder's whole purpose is being opened on devices that can't read HEIC.
Free tier: 2 GB — the smallest of the group, enough to test the workflow but not to live in.
Amazon Photos: The Sleeper Pick for Prime Members
If you already have an Amazon Prime membership, Amazon Photos includes full-resolution photo storage at no extra cost, with videos counting against a separate, much smaller allowance. It supports HEIC uploads from the iOS app, and for pure photo archiving it's one of the most generous deals going. The app and organization tools are weaker than Google's, and it's a poor fit if your library is video-heavy — but as a second, independent copy of an iPhone photo library it's hard to argue with, especially since you may be paying for it already.
Side by Side: HEIC Handling at a Glance
| Service | Keeps HEIC original? | Free tier | Best for |
|---|---|---|---|
| iCloud Photos | Yes, always | 5 GB (shared) | Apple-only households |
| Google Photos | Yes, in Original quality; recompressed in Storage saver | 15 GB (shared) | Cross-platform libraries |
| OneDrive | Configurable at upload | 5 GB | Microsoft 365 users |
| Dropbox | Configurable at upload (HEIC or JPG) | 2 GB | Folder-based workflows |
| Amazon Photos | Yes, for photos | With Prime membership | A second, independent copy |
The Setup We Recommend
After all the comparisons, here's the flow that keeps your photos both safe and usable:
- Keep shooting HEIC. Don't switch your camera to JPEG just for compatibility — you'd double your storage use everywhere to solve a problem that's fixable in seconds later. Leave Settings → Camera → Formats on "High Efficiency."
- Store originals in one primary cloud. iCloud if you're all-Apple; Google Photos with Original quality if you're cross-platform. Never let your only copy be a recompressed one.
- Convert copies on demand, not your library. When a Windows PC, a form, or a print service rejects HEIC, convert just those files — one at a time or in bulk, right in your browser, with nothing uploaded to any server. Need to check what's in a file first? The HEIC viewer opens them without converting anything.
- Add one copy that isn't in the cloud. Any serious backup habit includes a local copy on hardware you own, so a lost password or closed account can't take your library with it. As an Amazon Associate, OpenMyHEIC earns from qualifying purchases. A basic external hard drive is enough — copy your originals over a couple of times a year and unplug it. Our guide to backing up iPhone photos to an external hard drive walks through the three ways to do it, including one that skips the computer entirely.
Do You Really Have to Pay for Cloud Storage?
For a photo library of any size: realistically, yes — eventually. The free tiers exist to get you started, and 5 GB disappears fast when a minute of 4K video swallows hundreds of megabytes. That said, you can delay the paid tier considerably by exploiting HEIC's efficiency: because each photo is roughly half the size of a comparable JPEG, uploading originals instead of converted JPEGs effectively doubles what any plan holds. Converting your whole library to JPEG before uploading — a surprisingly common habit — is the single most expensive mistake in this workflow.
How Do I Get Thousands of Photos Off My iPhone?
If the real goal is freeing up phone space rather than choosing a cloud: turn on your chosen service, let it finish uploading (keep the app open and the phone charging — background uploads are slow), verify a sample of photos actually opens from another device, and only then clear space locally. If some of those photos need to be usable as JPGs on a PC along the way, you can convert HEIC to JPG right on the iPhone before or after — but the cloud copy should stay in the original format.
For a one-off move of a large library, the fastest route isn't the cloud at all: plugging the phone in and transferring the photos to a PC with a USB cable moves gigabytes without touching an upload quota or an internet connection.
Whichever service you pick, the principle is the same: the cloud stores your originals; conversion is something you do to copies, whenever a device demands it. Get that order right and the HEIC "problem" stops being a problem at all.
