You connect an iPhone to a laptop, open Photos and see fewer images than on the phone. Often, full originals are in iCloud while the device keeps storage-optimised versions. Cable import and iCloud access are different routes. Choose according to where the original files live, then verify a separate Windows copy before removing anything.
1. Find where the full originals live
Check iCloud Photos settings to see whether syncing and storage optimisation are enabled. Apple says full-resolution originals must be downloaded to iPhone before cable import to a Windows PC when iCloud Photos is on. If phone storage is tight, downloading the entire library may be impractical; iCloud for Windows or iCloud.com can be a better path.
A thumbnail in Photos does not prove the full file is stored locally. Try opening an older photo or video without a connection and see whether it needs a download. This guides the transfer method.
2. Import with a cable and Windows Photos
Microsoft describes connecting with a USB cable that transfers files, unlocking the phone and choosing Import from the connected device in Windows Photos. iPhone may ask whether to trust the computer; approve only a machine you control. Choose the files and destination, then wait for import to finish before disconnecting.
iPhone 13 has Lightning while iPhone 15 Pro has USB-C, but the correct connector is not enough if a lead is charge-only. If Windows does not detect the phone, try another data cable or port and ensure the phone is unlocked.
3. Use iCloud for Windows for cloud-held photos
Apple lets you view and download iCloud Photos through iCloud for Windows or iCloud.com. File Explorer may initially show thumbnails; open or download items to get the files. Copy the media you want to retain into a separate folder on your drive.
An iCloud folder is a sync location, not an independent backup. Apple notes that moving or deleting items in Microsoft Photos with newer iCloud for Windows versions may affect other devices. For backup, create a copy outside the synced area and confirm it opens.
4. Check file formats and copied originals
Open sample photos from different months and a longer video on the laptop. If HEIC or HEVC files are not viewable, check Windows format support rather than assuming the files are corrupt. Apple says the Most Compatible setting creates JPEG/H.264 for future captures; it does not convert the entire existing library.
Compare file counts, folder size and important photos before clearing phone storage. Keep another copy of irreplaceable media on another drive or service so one device is not the only place it exists.
5. Match storage to your photo workflow
A used iPhone 15 Pro and Dell 15 laptop illustrate a phone-to-Windows setup. A used iPhone 13 follows the same idea with a different suitable cable. Storage and price depend on the exact SKU.
If you record substantial video, consider space on iPhone, laptop and iCloud before buying. A good transfer workflow lets you find and open the files later, not merely watch a progress bar reach 100%.
Conclusion
Know where the originals are before choosing cable or iCloud, and verify copies before deleting anything. Sources: Apple on transfer to PC, iCloud Photos on Windows, Microsoft on importing photos and Apple on iCloud sync and deletion.
