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

Short answer

Don’t delete anything yet. Treat this as a syncing/download state: keep the device on Wi-Fi and power, confirm you’re signed into the correct account, and check whether the full-resolution originals are still visible in the cloud or on another device.

Do not do these things

  • Don’t start deleting “duplicates”, clearing albums, or emptying “Recently Deleted” while things look missing.
  • Don’t sign out of your Apple Account/Google Account “to reset it” unless you’ve confirmed your photos are safely visible elsewhere first.
  • Don’t factory reset, restore, or run “clean-up” apps that promise photo recovery.
  • Don’t turn off iCloud Photos/Google Photos backup as a quick fix. If a prompt says it will remove items from this device, stop and cancel until you’ve verified where your originals are.
  • Don’t assume low-quality previews mean permanent loss; they’re often placeholders while originals download.

What to do now

  1. Pause and protect what’s on this device.
    If you’re panicking and worried you’ll delete something, step away from the Photos grid for 30 seconds. Your main risk right now is an irreversible tap.

  2. Check the common “not actually gone” places Apple flags.

    • In Apple Photos: check Recently Deleted and Hidden.
    • If you use iCloud Shared Photo Library, switch between Personal Library and Shared Library views (photos can appear in one view and not the other).
    • Check your Library filters/view (for example, make sure you’re seeing All Items, not a filtered subset).

  3. Confirm you’re in the right account and syncing is enabled.
    In your device settings, confirm you’re signed into the Apple Account/Google Account you expect, and that iCloud Photos/Google Photos backup/sync is turned on.

  4. Give “optimising” the conditions it needs to finish.
    Plug the device into power, connect to reliable Wi-Fi, and (if it’s on) turn off Low Power Mode. Leave Photos open for a while so it can fetch originals/index.

  5. Do the safety check: are the originals still visible elsewhere?
    Use another device on the same account (iPad/Mac/another phone) or the service’s web photo library view.

    • If photos look normal there, your originals likely still exist and this device is showing reduced versions while it syncs/downloads.
    • If they’re missing there too, stop changing settings and move to support escalation (step 9).

  6. Check storage + the “optimised vs originals” setting before changing it.
    If device storage is very low, Photos may keep smaller versions locally and download originals on demand. Only switch to “download/keep originals” if you have enough free device storage and stable Wi-Fi.

  7. If only some items won’t load (error icons / blank previews): document it.
    Take screenshots of the “optimising” message, any error icons, and your storage screens. Note roughly when it started (after update, sign-in, storage running low).

  8. If you suspect account compromise: secure access first.
    Change your account password, review signed-in devices/sessions, and enable two-factor authentication. If you believe this involves fraud in the UK, it may be appropriate to report to Action Fraud.

  9. Escalate to official support with your notes.
    Contact Apple Support / Google Photos Help and share: whether the cloud/web view shows the originals, what’s in Recently Deleted/Hidden, storage levels, and any error icons.

What can wait

  • You don’t need to reorganise albums, deduplicate, or “clean storage” today.
  • You don’t need to decide whether to leave iCloud/Google Photos or switch services right now.
  • You don’t need to run recovery software or pay anyone while the status is “optimising”.

Important reassurance

This pattern is extremely often a temporary state: devices may show low-quality previews or gaps while originals download, views/filters change, indexing runs, or syncing catches up—especially after updates, sign-ins, or storage pressure. Your job right now is to avoid irreversible actions while you verify where the originals still exist.

Scope note

These are first steps to stabilise and verify whether your originals still exist in the cloud/another device, and to prevent accidental deletion. If verification shows items are truly missing everywhere, you may need deeper, service-specific support.

Important note

This is general information, not professional advice. If any screen warns that turning something off will remove items from your device, stop and read it carefully before proceeding.
