Copy photos to external storage, verify every byte, then delete with confidence.
Every file is hashed with SHA-256 while it is written to your drive. Once written, the file is read back off the drive and hashed again. Only a byte-for-byte match is marked verified. Anything that does not match is reported as failed — never silently accepted, and never offered for deletion.
No. Deleting is always a choice you make, and it is only ever offered for items that passed verification. iOS then shows its own confirmation on top of that, and anything removed goes to Recently Deleted, where it stays recoverable for 30 days.
Any drive formatted exFAT, FAT32, or APFS that your iPhone can reach through the Files app — USB-C flash drives, portable SSDs, and card readers all work the same way. If your iPhone can see it in Files, PhotoKopie can write to it.
No. Transfers happen entirely on your device. The one exception is a photo that lives only in iCloud and has not been downloaded yet — that original has to come down before it can be copied, which needs a connection and can make those items noticeably slower.
Yes. The Drive tab lets you browse a folder and import files back into your photo library, with the same option to remove them from the drive once they are verified in Photos.
Your photos are never uploaded. Copies go directly from your library to the folder you picked. There is no account, no cloud service, and no server holding your images. The app records anonymous counts of purchase and promo-code events so we can tell whether pricing is working; these contain no photo data and nothing that identifies you.
PhotoKopie uses the system Files picker, so a drive has to be visible to Files first. Open the Files app and confirm the drive appears under Locations. If it does not, the usual causes are a format iOS cannot mount (NTFS is not supported — reformat as exFAT), a drive drawing more power than the phone supplies (use a powered hub), or a cable that carries power but not data.
That item is almost certainly an iCloud original being downloaded before it can be copied. Large videos take the longest. Staying on Wi-Fi helps, and the transfer continues on its own once the download finishes.
A failure means the copy did not match its hash, or the drive refused the write — most often because it filled up or was unplugged mid-transfer. Failed items are left completely alone: the original stays in your library and is never offered for deletion. Free up space on the drive, or reconnect it, and run the batch again.
Pausing waits for the file in flight to finish, so a batch never pauses halfway through a file. Stopping does the same and then simply does not start the next one. Files are written under a temporary name and only renamed into place once complete, so an unplug cannot leave behind a partial file that looks successfully copied.
Copying continues briefly in the background and you will get a notification when the batch finishes. iOS limits how long any app can keep working once it is off screen, so for a large transfer it is best to leave PhotoKopie open — it keeps the screen awake for you while it runs.
Open the unlock screen and tap Restore Purchases. The purchase is tied to the Apple ID that bought it, so make sure the device is signed in to that same Apple ID. If a purchase is awaiting approval through Ask to Buy, it unlocks automatically once approved.
Into Recently Deleted in the Photos app, where iOS keeps them for 30 days before removing them permanently. Nothing PhotoKopie deletes bypasses that.
PhotoKopie never uploads your photos anywhere. Copies go straight from your photo library to the drive you choose, on your device. Nothing is deleted until you confirm it — twice.
