Google Photos Duplicates: How to Find and Remove Them

Google Photos has no duplicate finder, but you can still remove most duplicates with what Google gives you. Turn on photo stacks and keep one photo from each stack, search by date or filename for older copies, check Drive for "Copy of" files, and use a Google Takeout export for a full sweep. Then empty the Trash so the space comes back now.

Why do duplicates pile up in Google Photos?

Google Photos won't back up a file it already has, but that check only recognises the same file. Edits, crops, re-compression, format changes and re-saves all produce new files. A photo that arrives through WhatsApp, gets screenshotted, or is downloaded from a shared album uploads again as if it were new, so copies build up quietly.

There is a second source most people forget: Google Photos and Google Drive share one storage quota but not a duplicate check. A photo you uploaded to Drive to share with someone, and which is also backed up through Photos, is stored twice. The Photos vs Drive duplicate storage problem covers that case in detail, and what Google Photos duplicate detection actually does explains the upload check.

Method 1: photo stacks (Google's closest thing to a duplicate finder)

Photo stacks group nearly identical photos of the same subject taken together within a short time, and suggest a top pick. To turn them on, open the Google Photos app, go to the Photos tab, tap More (⋮) and switch on Stack similar photos. Open any stack and use Keep one photo & delete the rest, or multi-select the frames you don't want and move them to Trash.

Three limits, all from Google's own help page: stacks exist only in the mobile app, only for backed-up photos, and grouping recent shots takes a while. Stacking by itself frees nothing; the storage only drops when you delete. And stacks group shots taken together, so the same photo saved again a month later won't join the stack. For burst-heavy libraries, finding and deleting similar photos in Google Photos goes further, and blurry frames have their own pass in deleting blurry photos in Google Photos.

Method 2: search by date or filename

Type a date into the Google Photos search bar, or part of a filename like IMG_1234. Copies saved on the same day line up next to each other, so you can select the extras and delete them. Content search works too: "beach 2024" or a person's name gives you a smaller set to scan for repeats. On the web, click the first photo's checkmark and shift-click the last to select a range; the bulk delete guide has the phone equivalents.

The limit is that you have to know where to look. Re-saves from messaging apps and copies from years apart won't line up in any one search result.

Method 3: check Google Drive for copies

At drive.google.com, search for "Copy of" and sort by name to spot files ending in (1) or (2). These come from repeated uploads and from collaborators saving their own copy. drive.google.com/drive/quota lists your files largest first, which is where duplicate videos stand out. The Drive duplicate files guide covers shortcuts versus real copies.

Method 4: a full sweep with Google Takeout

For a large library, the only way to compare every photo against every other photo is to download them. Go to takeout.google.com, deselect everything except Google Photos, and export. Run a desktop duplicate finder that uses perceptual hashing (a fingerprint of what the image looks like, so resized and re-compressed copies still match) over the download. It gives you a list of duplicate filenames and dates. Search for those in Google Photos and delete the extras there, because deleting from the download does nothing to your cloud copy.

Why not an app that connects to your Google account and does it all? Since 31 March 2025, Google's Photos Library API only lets third-party apps read photos they uploaded themselves. Anything else has to be picked by hand through Google's Picker API. Be wary of any tool that claims to scan your whole Google Photos library in the cloud; check what access it actually asks for. The duplicate finder comparison goes through the options.

Which method finds what?

Google's storage manager (Photos settings → Backup → Manage storage) flags blurry photos, screenshots and large videos. It's worth running in the same session, but it has no duplicates category.

How to remove duplicates in Google Photos, step by step

1. 1

   Turn on photo stacks

   In the Google Photos app, open the Photos tab, tap More (⋮) and turn on Stack similar photos. Nearly identical shots taken together are grouped with a suggested top pick. Open a stack and choose Keep one photo & delete the rest.

2. 2

   Search by date or filename

   Type a date or a partial filename (like IMG_1234) into the Google Photos search bar. Copies saved on the same day cluster together; select the extras and move them to Trash.

3. 3

   Check Google Drive for 'Copy of' and '(1)' files

   At drive.google.com, search for 'Copy of' and sort by name to spot files ending in (1) or (2). Drive shares your storage quota with Photos, so those copies count too.

4. 4

   Sweep a large library with Google Takeout

   Export Google Photos at takeout.google.com, run a desktop duplicate finder on the download, then search for the flagged filenames in Google Photos and delete them there.

5. 5

   Empty the Trash

   Deleted photos stay in Google Photos Trash for 30 days. Collections → Trash → More → Empty Trash gets the space back now instead of in a month.

Empty the Trash to get the space back

Photos you delete go to Trash and are permanently deleted after 30 days. If you need the space now, open Collections → Trash, tap More and Empty Trash. Drive has its own Trash, and Google counts files left in it against your storage, so empty that too.

That 30-day window is also your safety net. If you delete a group by mistake, restore it from Trash before the window closes. If storage is the reason you're here, the Google Photos storage full checklist and the Google storage full guide cover the other categories worth clearing.

Duplicates on the phone, not in the cloud

If the copies you want gone are in your iPhone camera roll instead, the on-device version of this job is covered in deleting duplicate photos on iPhone, with a wider iPhone photo cleanup guide alongside it. Clearing the phone first also means fewer copies get backed up to Google Photos again.
