You can also add a bunch of photos and duplicates to an album (it can have 20.000 photos now), and sort by upload date (Open the album > click 'More options' (3-dots ) > click 'Sort' (2 arrows) > 'Recently added'. That separates two sets of same photos so that you can select a range to delete. It may be easier to delete batches of duplicates in where they are sorted by upload date (most recent on top). One photo may have more pixels or more KB or MB (see info of the photo) You can see in the info panel to which album(s) a photo is added and add the photo you want to keep to ALL albums. One photo may be in an album, the other not or in more/different albums.

You need to open the photo and click the edit icon to find out.ĭeleting a photo removes it from ALL albums. You may have to check which ones you can delete: When you add for example something in the Description field', and it also appears in the second photo, there is in fact only one photo, and deleting one will delete both.

You can delete duplicates manually, for example in where they should be next to each other except when date/time was changed.ĭuplicates may also appear together in albums created by Google under People, Places and Things, but you have to be careful: sometimes a photo is shown twice. There is no easy way to remove duplicates in Google Photos (prevention is important!), but this may help a bit:
