Photomator and Apple Photos are a natural pair. Apple Photos holds your library, syncs it across Mac, iPhone and iPad, and keeps your originals safe. Photomator adds deeper editing, masking, AI tools and batch work. Used well together, they give you powerful editing without a second library, without exported copies piling up, and without duplicates.
Used badly, the pair can create exactly the mess people fear: an edited copy in one app, the original in another, a shared version in a third place, and no clear answer to which file is the real one. This guide explains how to edit in Photomator with Apple Photos as your library, keeping one version of each photo and avoiding duplicates.
Understand how the two apps work together
Photomator can open photos from your Apple Photos library and save edits back to the same photo, non-destructively. That means the original is preserved, the edit is stored with it, and you can revert to the original at any time. You do not need to export a copy to edit it, and you do not need to import an edited copy back into Photos.
The key habit is to let Apple Photos be the library and Photomator be the editor. Open the photo from Photos, edit it in Photomator, and save it back to the same library entry. If you export a copy instead, give it a clear purpose, such as sharing or printing, and treat it as a disposable output, not as a second library copy.
Edit without creating duplicates
To avoid duplicates, follow a simple rule: one photo, one library entry. In Photomator, edit the photo from your library rather than importing a separate file, and save back to Photos rather than saving a new file to a folder. If you need a version for a specific purpose, such as a black-and-white version for a print, consider whether you need a separate file at all, or whether a reversible edit and a shared export will do.
Be careful with sharing and messaging. When you share a photo from Photos or Photomator, the shared copy lives in the message or post, not in your library, and that is fine. The duplicate problem starts when shared or exported copies are saved back into the library. Check your library regularly for near-identical copies, and delete the extra copy only when you are sure which one is the original with the edit you want to keep.
Keep edits reversible and organised
Non-destructive editing is your safety net. In Photomator, keep edits reversible so you can return to the original, refine an edit later, or try a different version without losing work. Use albums and favourites in Apple Photos to organise photos, rather than creating folders of exported copies on your Mac. A photo that lives in one library entry and appears in an album is organised without being duplicated.
For a series of photos, such as a trip or an event, edit one representative photo in Photomator, save a preset, and apply it across the set in the library, refining each photo as needed. Keep the same approach to naming and albums, so you can find the set later without searching through exported files.
Sync, backup and a tidy workflow
Apple Photos syncs your library across devices through iCloud, so an edit made in Photomator on your iPhone can be available on your Mac. Let the sync finish before editing the same photo on another device, to avoid conflicting versions. Keep a backup of your library, as you would for any important collection, and treat the library as the single source of truth.
A tidy weekly habit helps: review recent edits, remove any exported copies that have crept into the library, and check that albums are up to date. When you are reading other Photomator guides, you will see the same principle. A clean library is not about having fewer photos, it is about having one clear version of each photo, edited well and easy to find.
Frequently asked questions
Does editing in Photomator create a duplicate in Apple Photos?
Not when you edit from the library and save back to the same photo. Photomator saves edits non-destructively to the same library entry, preserving the original and letting you revert. Duplicates come from exporting and re-importing copies, not from editing in place.
Can I revert a Photomator edit made through Apple Photos?
Yes. Because the edit is stored non-destructively with the original, you can revert to the original in Apple Photos at any time. Keep edits reversible and avoid overwriting the original with an exported copy.
Should I export copies for sharing?
Export a copy for sharing or printing when you need one, and treat it as a disposable output, not a library copy. Share from the library where you can, and avoid saving shared or exported copies back into Photos.
How do I organise photos without duplicating them?
Use albums and favourites in Apple Photos rather than folders of exported copies. One library entry can appear in several albums without being duplicated, and it stays easy to find.
What if I already have duplicates in my library?
Check which copy is the original with the edit you want to keep, and delete the extra copy only when you are sure. Then switch to editing from the library and saving back to the same entry, so new duplicates do not appear.
