How to Hide Photos on iPhone (the Private, Encrypted Way)
Whether it's financial documents, personal photos, or anything else you'd rather not have on display, most people have a few pictures on their iPhone they'd prefer to keep private. The problem is that the iPhone's built-in tools were never really designed to keep photos secret — just slightly out of the way.
Here's how photo hiding on iPhone actually works, why the built-in Hidden album falls short, and how to lock your private photos and videos in a genuinely encrypted vault.
Why the iPhone "Hidden" Album Isn't Really Private
iOS has a built-in Hidden album. You select a photo, tap the share or more button, and choose Hide. It disappears from your main library and moves into a Hidden folder inside the Photos app.
On newer versions of iOS that Hidden album is locked behind Face ID by default, which is better than nothing. But it has real limitations:
- Anyone with your passcode can open it. Face ID falls back to your device passcode — so a partner, family member, or anyone who knows your PIN can view everything inside.
- The photos aren't separately encrypted. They still live in your normal photo library and sync to iCloud Photos like any other image.
- It's obvious. The Hidden album is right there in the Albums tab. Its existence isn't a secret, and there's no way to disguise it.
- No protection against a shoulder-surfer who grabs your unlocked phone — the album opens with the same Face ID that's already unlocked the device.
For casually keeping a photo out of your camera roll, the Hidden album is fine. For anything you genuinely need to keep private, it isn't enough. Sorting the rest of the library by what is in the picture, rather than hiding it, is organizing photos with Smart Albums.
The Better Option: A Real Encrypted Vault
A dedicated photo vault solves what the Hidden album can't. Instead of just moving a photo out of view, a proper vault encrypts it and stores it behind its own separate lock — independent of your device passcode.
Phone Diet runs on iPhone and iPad (iOS 17.0 or later, or iPadOS 17.0 or later). Similar Photos groups near-identical shots and marks the best one 'Keep'. Duplicates are exact copies. It also finds blurry and dark photos, screenshots, screen recordings, Live Photos, and bursts, and it lists Largest Files. Photos never leave the device. Video compression uses HEVC and can make a video up to 70% smaller. Undo has a countdown, and Recover keeps removed items for 30 days, or 7 or 60. Smart Albums, swipe to sort, and On This Day are included. The full scan is free, and the first cleanup of up to 1 GB is free.
How to Hide Photos in the Private Vault
The Private Vault hides photos behind Face ID, Touch ID, or a passcode. It is encrypted and stored only on the device. The listing does not describe a PIN length or a separate charge for adding items.

What Makes a Vault Actually Private
Not all "hide photo" apps are equal. Many free ones simply move files around, show ads, or — worse — upload your photos to their own servers. Here's what genuine privacy looks like, and what to check for:
- On-device encryption. Your photos should be encrypted and stored on your phone, never uploaded. Phone Diet runs entirely on-device — there's no server that ever sees your images.
- A separate lock. The vault should have its own PIN, not just reuse your device passcode, and re-authenticate before sensitive actions like changing the PIN.
- No ads, no tracking. A privacy tool that monetizes your data isn't a privacy tool. Phone Diet runs no product analytics and no ad tracking.
Don't Forget the Originals
Hiding a photo is pointless if a copy is still sitting in your camera roll. When you move a photo into the Private vault, the app removes it from your main library automatically once the encrypted copy is verified. But it's worth doing a quick sweep afterward:
- Check Recently Deleted in Photos and clear it, since deleted originals linger there for 30 days.
- If you use iCloud Photos, remember that hiding within the stock Photos app still syncs — another reason a separate encrypted vault is the safer choice.
The Bottom Line
The iPhone's Hidden album is convenient, but it's a privacy feature in name more than in practice: it rides on your device passcode, keeps photos in your normal library, and hides in plain sight. If you have photos or videos you genuinely need to keep private, move them into a real encrypted vault with its own lock.
