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

  1. Connect the iPhone and unlock it.
  2. Open Photos. The iPhone appears in the sidebar under Devices.
  3. Click Import All New Items, or select specific photos and click Import Selected.
  4. 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:

  1. Connect and unlock the iPhone, tap Trust.
  2. Open File Explorer and find Apple iPhone under This PC.
  3. Go to Internal Storage → DCIM. Your photos are inside folders named 100APPLE, 101APPLE and so on.
  4. 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

FAQ

How do I transfer photos from an iPhone to a computer without iTunes?
You do not need iTunes at all. On Windows, open File Explorer, find Apple iPhone under This PC, and copy from Internal Storage → DCIM. On a Mac, use the Photos app or Image Capture. For a small batch, a browser transfer needs no software on either side.
Why can't my computer see my iPhone?
Almost always because the phone is locked or you have not tapped Trust This Computer. Unlock the phone, plug it in again, and accept the prompt. If nothing appears at all, the cable may be charge-only - try another one.
Why are my iPhone photos .HEIC and how do I open them on Windows?
iPhones shoot HEIC by default to save space. Install the free HEIF Image Extensions from the Microsoft Store to open them, or set Settings → Camera → Formats → Most Compatible to shoot JPEG from now on. You can also set Settings → Photos → Transfer to Mac or PC → Automatic so the phone converts as it transfers.
Why does my photo import keep stopping partway?
Copying thousands of files over MTP on Windows is fragile, and one unreadable file can stall the whole queue. Import in batches of a few hundred instead of selecting the entire camera roll. Keeping the phone unlocked during the transfer also helps.
Can I transfer iPhone photos to a Windows PC wirelessly?
Yes. iCloud for Windows syncs them if you have the storage, and a browser transfer sends a batch with no account and no app - open the page on the PC, scan the code with the iPhone, and pick your photos.
Will transferring compress my photos?
Not with any method here. Cable imports, iCloud with Keep Originals, and browser transfers all move the original file. Emailing photos or sending them through a chat app is what compresses them.
