Your iPhone says Storage Almost Full, and 4,000 photos are the reason. You plug it into the computer, and either nothing happens, the Photos app imports 12 of them and stalls, or every file lands as a .HEIC that Windows refuses to open.
None of that is your fault. Apple's import path is genuinely fiddly, and it behaves differently depending on whether you are on a Mac or a PC. This guide covers both, plus the way that skips the cable entirely.
Key takeaways
- On a Mac, the Photos app import is the fastest route for a whole library - it copies originals and handles HEIC natively.
- On Windows, your iPhone appears as a camera in File Explorer under
Internal Storage\DCIM. You do not need iTunes to copy photos.- HEIC is the usual culprit when photos won't open on Windows. Install HEIF Image Extensions, or set your iPhone to shoot JPEG.
- For a handful of photos, a browser transfer is faster than any of it - no cable, no import wizard, nothing to install.
- Always unlock the iPhone and tap Trust before the computer will show any files at all.
First: unlock and trust
Nearly every "my computer can't see my iPhone" problem is this. An iPhone shows nothing to a computer while it is locked. Plug it in, unlock it, and tap Trust This Computer on the prompt, then enter your passcode.
If the prompt never appears, unplug, lock and unlock the phone, and plug back in. A charge-only cable will also never show files - if the phone charges but no prompt appears, try a different cable before assuming anything is broken.
On a Mac: the Photos app
- Connect the iPhone and unlock it.
- Open Photos. The iPhone appears in the sidebar under Devices.
- Click Import All New Items, or select specific photos and click Import Selected.
- Tick Delete items after import only once you have confirmed the import finished.
This keeps full resolution and handles HEIC without conversion, because macOS reads HEIC natively. If you would rather have plain files in a folder than a Photos library, use Image Capture (in Applications) instead - it does the same import but lets you choose a destination folder.
On Windows: File Explorer, no iTunes needed
You do not need iTunes to copy photos. Windows treats an iPhone as a camera:
- Connect and unlock the iPhone, tap Trust.
- Open File Explorer and find Apple iPhone under This PC.
- Go to Internal Storage → DCIM. Your photos are inside folders named
100APPLE,101APPLEand so on. - Select what you want and copy it to a folder on the PC.
Two things trip people up here. Those DCIM folders hold roughly 1,000 files each, so a large library is spread across several. And copying thousands of files over MTP - the protocol Windows uses for phones - is slow and prone to stalling. For a full library, import in batches of a few hundred rather than selecting everything at once.
The Windows Photos app can also import: open it, click Import → From a connected device, and pick what you want.
Fixing HEIC files Windows won't open
Since iOS 11, iPhones shoot in HEIC by default. It is a better format - roughly half the file size at the same quality - but older Windows builds don't read it.
Two fixes:
- Install HEIF Image Extensions from the Microsoft Store (free). Windows then opens HEIC files like any other picture.
- Shoot JPEG instead: on the iPhone, Settings → Camera → Formats → Most Compatible. This only affects new photos, not ones you already took.
There is also a middle path built into iOS. In Settings → Photos, scroll to Transfer to Mac or PC and choose Automatic - the iPhone then converts HEIC to JPEG as it transfers. Choose Keep Originals if you want the untouched HEIC files.
Without a cable: send them in a browser
If you want twenty photos rather than four thousand, the cable is more trouble than it is worth. Open phone to computer transfer on the computer, scan the code with the iPhone camera, pick the photos, and they appear on the computer screen. No cable, no iTunes, no import wizard, and nothing to install on either device.
This sends the original files, so a photo arrives at full resolution with its EXIF data intact. It handles up to 100 files or 3 GB in one go, which is comfortably a day of shooting. Going the other way works too - see computer to phone.
It is also the only method on this page that works when the cable is in another building.
iCloud Photos: already done, maybe
If iCloud Photos is switched on, your photos are already off the phone. On a Mac they appear in Photos automatically. On Windows, install iCloud for Windows and they sync into a folder.
The catch is the free tier: 5 GB does not hold a modern camera roll, so most people's iCloud is full and silently not syncing. Check Settings → [your name] → iCloud on the phone before you rely on it.
Also watch Optimise iPhone Storage. With it on, the phone holds smaller versions and the originals live in iCloud - so a cable import can pull down compressed copies rather than the real thing. Turn it off and let the phone re-download the originals first if you are archiving.
Which method for which job
| Method | Best for | Speed | Setup | Keeps original quality |
|---|---|---|---|---|
| Mac Photos / Image Capture | Whole library on a Mac | Fast | None | Yes |
| Windows File Explorer | Whole library on a PC | Slow over MTP | None | Yes |
| iCloud Photos | Ongoing, hands-off | Depends on Wi-Fi | Account, paid storage | Yes, if not optimised |
| Browser link | A batch you need now | Fast | None | Yes |
