The direct answer: you need a computer in between

You cannot plug a flash drive directly into an iPhone — iPhones do not have a USB port that accepts standard flash drives, and iOS does not support that connection method. Instead, you move photos from your iPhone to a computer first (Mac or Windows), then copy them to the flash drive from there. The whole process takes about 10 minutes once you have the right cable.

The cable you need depends on your iPhone model. iPhones from 2019 onward use USB-C, while older models use Lightning connectors. You also need a computer with a USB port and a flash drive with at least 16 GB of free space (photos are typically 2 to 4 MB each, so 100 photos need roughly 400 MB).

Key Takeaways

  • iPhones require a computer as an intermediary — you cannot connect a flash drive directly to an iPhone.
  • On Windows, use File Explorer to import photos from your iPhone, then drag them to the flash drive; on Mac, use the Photos app or Finder depending on your macOS version.
  • Your iPhone will ask for permission the first time you connect it to a computer — tap "Trust" on the phone to allow the transfer.
  • Photos imported to a computer are stored as standard image files (usually JPEG or HEIC format) that work on any device.

Windows: using File Explorer to move photos

Plug your iPhone into the computer using the correct cable (USB-C for newer models, Lightning for older ones). Windows will recognize the iPhone as a device. On your iPhone screen, a prompt will appear asking "Trust This Computer?" — tap "Trust" to allow the connection.

Open File Explorer on your Windows computer. In the left sidebar, you should see your iPhone listed under "This PC" with a name like "iPhone" or "[Your Name]'s iPhone". Click on it, then navigate to Internal Storage > DCIM > 100APPLE (or a similar folder — the exact name varies). This folder contains all your photos. Select the photos you want to export (Ctrl+A selects all), then right-click and choose "Copy".

Plug your flash drive into an empty USB port on the computer. It will appear in File Explorer. Open the flash drive, right-click in the empty space, and choose "Paste". Windows will copy the files. Once the progress bar finishes, right-click the flash drive in File Explorer and select "Eject" before unplugging it.

Mac: using Photos app or Finder

Connect your iPhone to the Mac using the correct cable. On your iPhone, tap "Trust" when prompted. On your Mac, the Photos app usually opens automatically. If it does not, open Photos from your Applications folder. Your iPhone will appear in the sidebar under "Devices". Click it, and you will see thumbnails of all your photos and videos.

Select the photos you want to export. You can click one, then hold Shift and click another to select a range, or hold Command and click individual photos to select multiple ones scattered throughout your library. Once selected, click the "Import" button in the top right. Photos will ask where to import them — choose "New Album" or "Recent" (the default). The photos are now on your Mac's hard drive.

Plug your flash drive into a USB port on the Mac. Open Finder and locate the flash drive in the sidebar. In a separate Finder window, navigate to Photos > Library > Photos Data (or wherever you imported the photos). Drag the photo files to the flash drive window. Once the copy finishes, eject the flash drive by right-clicking it in Finder and selecting "Eject".

If you are using macOS Catalina or newer, the Photos app may not show an Import button. Instead, use Finder: connect your iPhone, open Finder, click the iPhone in the sidebar, navigate to DCIM > 100APPLE, select your photos, and drag them to a folder on your Mac. Then drag those files to the flash drive.

Understanding photo formats and file size

When you export photos from an iPhone, they are usually in JPEG format (older iPhones) or HEIC format (newer iPhones). JPEG works on any device — Windows, Mac, Android, or older cameras. HEIC is Apple's newer format and may not open on Windows or Android devices without additional software.

If you are exporting photos to a flash drive that will be used on Windows or Android devices, check the format before you copy. On your iPhone, go to Settings > Camera > Formats and choose "Most Compatible" instead of "High Efficiency" — this saves new photos as JPEG. Photos already on your phone in HEIC format will stay that way, but you can convert them on your computer using free tools like CloudConvert or by opening them in Windows Photos and re-saving as JPEG.

File size matters for flash drives. A typical iPhone photo is 2 to 4 MB. A 64 GB flash drive holds roughly 15,000 to 30,000 photos depending on resolution. If you are exporting videos as well, they are much larger — a one-minute 4K video can be 200 MB or more.

Troubleshooting: when your iPhone does not appear

If your iPhone does not show up in File Explorer or Finder after you plug it in, first check that you tapped "Trust" on the iPhone screen. If you did not see that prompt, unplug the cable, wait 10 seconds, and plug it back in. The trust prompt should appear again.

If the prompt never appears, try a different USB cable — some cables are damaged or designed only for charging, not data transfer. Apple's official USB-C and Lightning cables work reliably; third-party cables sometimes do not. If you have access to another computer, try connecting there to rule out a computer-side problem.

On Windows, if your iPhone appears but you cannot see the DCIM folder, your iPhone may have restricted access. Disconnect, then on your iPhone go to Settings > Privacy > Photos and make sure the app you are using (File Explorer, or a third-party tool) has permission. Reconnect and try again.

Alternative: using iCloud or cloud storage

If you do not have a computer available, you can upload photos to iCloud, Google Drive, OneDrive, or Dropbox from your iPhone, then download them on any computer and copy to a flash drive from there. This takes longer but works if you only need to export a few photos. Open the cloud service app on your iPhone, upload your photos, sign in on a computer, download them, and copy to the flash drive using the steps above.

This method is slower for large batches of photos because uploads depend on your internet speed. A direct computer connection is faster if you have hundreds of photos to move.

Frequently Asked Questions

Can I use a USB-C flash drive with a USB-C iPhone?

Yes, but you still need a computer. You cannot plug a USB-C flash drive directly into a USB-C iPhone — iOS does not support that connection. You must transfer photos to a computer first, then to the flash drive.

Will my photos look different after I export them?

No. Exporting copies the original image file without changing it. The photo will look identical on the flash drive as it does on your iPhone. If your iPhone stores photos in HEIC format and you open them on a Windows computer, they may look slightly different only if Windows does not have HEIC support installed — but the file itself is unchanged.

What if I want to export photos but keep them on my iPhone too?

Exporting copies the photos — it does not move them. Your originals stay on your iPhone. If you want to free up space on your iPhone after exporting, you delete them manually in the Photos app after confirming the copies are on the flash drive.

Can I export videos the same way as photos?

Yes. Videos appear in the same DCIM folder as photos on Windows, and in the Photos app on Mac. Select them the same way you select photos and copy them to the flash drive. Be aware that videos are much larger than photos — a one-minute video can be 200 MB or more, so make sure your flash drive has enough free space.

Do I need special software to export photos from iPhone?

No. File Explorer on Windows and Finder or Photos on Mac are built in and work without installing anything extra. Third-party tools exist but are not necessary for basic photo export.
