Find image duplicates

You can use our duplicate finder to locate duplicate images in your portal. The duplicates are found based on pHash comparison. You can decide which of the duplicate images should be marked as original and you can delete other duplicate images. Currently, there is no option to resolve or ignore duplicates.

How to Enable the Duplicate Image Finder?

By default, the Duplicate Image Finder is not enabled for your portal. Contact your Customer Success Manager to discuss if the Duplicate Finder can be enabled for your portal.


The Duplicate Finder is being worked on  for portals that are on Files Service. If your portal is not on Files Service yet you can still make use of the Duplicate Finder.

Not sure if you're on File Service? We sent out communication to our clients who are on File Service. Please contact your portal administrator for more information.

Use the duplicate image finder

  1. Navigate to the Asset Bank select a filter or search query to search duplicates for and click duplicate_finder-icon.png in your action bar.

    Note You can also find duplicates from a search query or after filtering your Asset Bank.

  2. In each row, you will see a set of images, with their asset title, description, and tags, that are considered duplicates. The sets are ordered in the same way your Asset Bank is ordered. So if you have the "sort by date added" arrangement applied, you will find the latest duplicates on top of the results list.

  3. The first image displayed is considered the original image, but you can click Make original for a different image to update this.

    a. The original image is chosen based on most pixels (width * height). If they are all the same it ranks on the ‘date uploaded.’

  4. To delete a duplicate, click the trashcan icon beneath the image or choose Delete all duplicates (#) to delete all non-original images.

  5. Note

    Note: Currently, metadata is not merged with the original image, so if you decide to delete a duplicate, its metadata gets deleted as well.

pHash comparison

We find duplicates based on pHash (perceptual hash) comparison. We turn the image to black and white, make it smaller, and calculate the hash. When you run the duplicate image finder, the hashes are compared and if they are the same, these images are considered duplicates
