You can transfer photos from an iPhone to a computer using several methods. The most straightforward approach is connecting your iPhone directly to your computer with a USB cable. On Windows, your iPhone appears in File Explorer as a device; open it and navigate to Internal Storage > DCIM to find your photos, then copy them to a desired folder. On Mac, the Photos app automatically opens when you connect your iPhone, and you can select photos to import. Alternatively, you can use iCloud Photos: enable iCloud Photos on your iPhone (Settings > Photos > iCloud Photos), then sign into iCloud.com from your computer and download photos from the Photos section. Another option is using Image Capture (Mac) or File Explorer (Windows) for more granular control—this allows you to organize and selectively transfer photos without syncing through Apple's cloud service. For backing up your entire photo library, iCloud Photos automatically stores everything in the cloud, accessible from any device. Email or messaging apps also work for transferring small batches of photos. The cable method is fastest for large quantities and doesn't require internet, while cloud options offer convenience and automatic backup across devices.
