Originals are backed up before anything is changed, and you can restore a whole batch or a single image from it. The one hard constraint is time: backups are kept for 30 days and then purged automatically. After that window the resized image is the only copy the app holds.
Check these in order
Open the run in History
Find the batch the images belong to.Check how many can still be restored
The restore option in a batch shows how many of its images can still be restored, so a batch showing fewer restorable images than it processed has passed its retention window for the rest.Restore the batch or one image
Press Restore all for the batch, or Restore beside a single image.
How to fix it
A restore runs in the background and puts each original back in place of the resized version. If the backups have expired, the app can no longer bring those originals back, so use your own copies of the photos.
If it still is not working
Send us the batch and the images you need: contact support.
