What to do if…
your photo library shows optimising and your photos look missing or low-quality

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Do not delete anything yet. Treat this as a sync, storage, or account-view problem until you have checked whether the full-resolution photos still appear in the cloud or on another trusted device.

Do not do these things

  • Don’t delete “duplicates”, clear albums, or empty Recently Deleted while the library looks wrong.
  • Don’t sign out, unlink this device, remove the app, or turn off photo syncing as a reset unless you have confirmed your originals are safely visible somewhere else.
  • Don’t factory reset, restore, or use a clean-up app that promises photo recovery.
  • Don’t ignore any warning that says items will be removed from this device. Stop and cancel until you know where the originals are.
  • Don’t assume low-quality previews mean permanent loss; they can be placeholders while originals download.

What to do now

  1. Stop the risky taps first.
    Put the device down for a moment if you feel panicked. The main thing to avoid right now is deleting, emptying, or switching off a sync feature before you know where the originals are.

  2. Check the places photos commonly appear to be missing from.
    In Apple Photos, check Recently Deleted, Hidden, and whether you are viewing Personal Library, Shared Library, or Both Libraries. In Google Photos, check the Bin, Archive, device folders, and any photo stacks.

  3. Check the account.
    Confirm the Apple Account or Google Account shown on this device is the one that normally holds the photos. If another phone, tablet, or computer uses the same photo library, check the account shown there too.

  4. Check the cloud view before changing settings.
    Open the web photo library for the service you use, or check another trusted device already signed in to the same account. If the photos look normal there, this device may only be showing reduced previews or an incomplete local view while it catches up.

  5. Give syncing the safest conditions.
    Connect the device to reliable Wi-Fi and power. Turn off Low Power Mode if it is on. Leave the photo app and device connected for a few hours, or overnight if the library is large.

  6. Check storage before asking for originals.
    If device storage is very low, the device may keep smaller versions locally and download originals when needed. Only choose an option such as downloading or keeping originals if there is enough free storage and the device is on stable Wi-Fi.

  7. Save what you can see without deleting anything.
    Take screenshots of the “optimising” message, any error icons, the storage screen, the sync or backup status, and the account email address shown. Note whether this started after an update, a sign-in, a new device, or a low-storage warning.

  8. If you suspect someone else accessed the account, secure access first.
    Change the account password from the official Apple or Google route, review signed-in devices, and turn on two-factor authentication if it is available. If this also involves fraud, blackmail, or stolen money or information, use the official reporting route for your nation.

  9. Use official support with the facts you have gathered.
    Contact Apple Support or Google Photos Help and tell them whether the web view shows the originals, which account is signed in, what is in Recently Deleted, Hidden, Bin or Archive, how much storage is free, and what exact message or icon you see.

What can wait

  • You don’t need to reorganise albums, merge duplicates, clear storage, or change cloud services today.
  • You don’t need to decide whether to keep using iCloud Photos, Google Photos, or another service right now.
  • You don’t need to pay for recovery software while the library is still showing “optimising” or syncing.

Important reassurance

This situation often turns out to be a temporary device view, storage, or sync problem rather than permanent loss. The safest first step is to avoid irreversible changes while you check whether the originals still exist in the cloud or on another device.

Scope note

These are first steps only. If the photos are missing from every device, the web photo library, and deleted-item areas, you may need service-specific support or specialist data recovery advice before making further changes.

Important note

This is general information, not legal, technical, data recovery, financial, therapeutic, or other professional advice. Read any device warning carefully before turning off sync, signing out, deleting items, or resetting anything.
