# Auto-Tag Photos — Tag photos automatically on Mac

Recognise what's in photos and add Finder tags, so Spotlight and Ask can find them. Part of OneMacTools, 151 private tools in one native Mac app (macOS 26 or later); category: On-device AI. Runs on your Mac; nothing is uploaded.

OneMacTools recognises what's in each photo on your Mac (a beach, food, a dog, a document) and adds those words as Finder tags. Then Spotlight, Finder and OneMacTools' Ask (⌘K) can find them by what they show. The pictures themselves aren't changed.

## How to use it
1. **Drop your photos.** Add a batch of photos, screenshots or other images onto Auto-Tag Photos.
2. **Choose how many tags.** In the right-hand panel, set Tags per photo to 1, 3 or 5.
3. **Choose how sure it must be.** Set Only when to Very sure for fewer, safer tags, or Fairly sure for more.
4. **Click Tag.** Each photo is recognised on your Mac, and the words, such as Beach, Food or Dog, are added to the photo's Finder tags. The window shows how many photos were tagged and the most common tags.
5. **Search by what they show.** Type a tag into Spotlight or a Finder search, click it under Tags in the Finder sidebar, or use OneMacTools' Ask (⌘K) to find the photos.

## Options
- **Tags per photo:** 1, 3 (the default) or 5. This is the most a photo gets; it gets fewer when fewer things are recognised clearly enough.
- **Only when:** Fairly sure, the default, tags anything recognised with reasonable confidence. Very sure only tags what's recognised with high confidence, so you get fewer tags but fewer odd ones.
- **Replace existing tags:** Off by default, so new tags are added next to any tags the photo already has, without duplicates. Turn it on to remove the existing tags first, including colour tags you added yourself.

## Tips
- Try the defaults on a small folder first, then run it on the rest once you like the tags.
- Use Very sure on a large collection to keep tags reliable.
- Leave Replace existing tags off if you use Finder colour tags such as Red or Work, or they'll be removed.
- Very broad labels, such as “outdoor”, “people” or “pattern”, are skipped because they don't help you find anything.
- Finder tags stay with the files on your Mac, but they're usually lost when a photo is emailed or uploaded.

## Questions
**How do I tag photos automatically on a Mac?**
Drop the photos onto Auto-Tag Photos and click Tag. Each one is recognised on your Mac and gets Finder tags for what it shows, such as Beach, Food or Document.

**How do I find photos by their tags?**
Type the tag into Spotlight or a Finder search window, or click it under Tags in the Finder sidebar. OneMacTools' Ask (⌘K) can find them too.

**What kinds of things does it recognise?**
Scenes, objects, animals, food, documents and more, using the image recognition built into macOS. It doesn't identify people by name.

**Will it remove the tags I already have?**
No, unless you turn on Replace existing tags. By default new tags are added alongside your own, and a tag the photo already has isn't added twice.

**Does it work with my Photos library?**
It works on image files in Finder. To tag pictures from Photos, export them to a folder first. Finder tags don't appear as keywords inside Photos.

**How do I remove tags it added?**
Select the photos in Finder, right-click and untick the tags, or remove them in Get Info. The pictures themselves were never changed.
