Are hidden photos encrypted on iPhone?

Hiding a photo moves it to a locked collection. It adds no encryption of its own. What protects hidden photos, and what would add more.

The word Hidden suggests more than the feature does. It removes pictures from the places people normally look. That is useful, and it is a separate thing from encryption.

What protects a hidden photo

A lock on the collection. Apple says Hidden is locked by default and opens with Face ID, Touch ID or your passcode. If you turned that off in Settings, it opens freely.

Device encryption. A passcode turns on data protection for the whole phone. This covers all your photos equally, whether hidden or not.

iCloud encryption. With iCloud Photos on, hiding applies on all your devices. Hidden items follow your account’s setting: Apple-held keys by default, or end-to-end with Advanced Data Protection. Apple notes that the hidden flag itself remains under standard protection.

What that means in real life

• A child or stranger with your locked phone cannot get in.
• A partner who has seen your passcode can.
• Anyone signed in to your Apple Account on another device can reach them with that device’s unlock.

If you want a separate secret

Encrypting a photo with a key your passcode cannot reach requires an app built for it. Backroom encrypts each file with AES-256-GCM using a random key for each vault, and your pattern unlocks that key. That has costs: nobody can recover a vault if you lose both the pattern and the 12-word phrase, and there is no sync to your other devices. Backroom has also not had an outside review yet. Here is the comparison.
