How to Merge and Deduplicate Photos Between Your Phone and NAS

(Without Uploading Everything to the Cloud)

TL;DR: This guide shows how to merge and deduplicate photos across your phone and NAS (WebDAV), plus self-hosted libraries like Immich/PhotoPrism—without uploading everything to a cloud service. You’ll connect sources in place, review duplicates, and clean up safely on the original storage.

If you store photos both on your phone and on a NAS, you’ve probably run into this problem:

  • The same photos exist on your phone, your NAS, and backups
  • Files were copied multiple times over the years
  • Storage keeps growing, but you’re not sure what’s safe to delete
  • Most photo apps assume one cloud library, not multiple sources
