Apple has confirmed that images made or changed with some Apple Intelligence tools now carry an invisible SynthID watermark. It arrives with the 27.2 updates for iPhone, iPad, Mac and Vision Pro, as Apple explained in a support page on November 5, 2026.
The tagged tools include the Photos tools Clean Up, Extend and Spatial Reframing, plus Image Playground and Image Wand.
This matters because the mark is not limited to fully AI-generated pictures. A real photo from your own library also gets the hidden tag once you touch it up with one of these editing tools, which means anyone who checks the file can learn that AI played a part in it.
At a Glance
- Some Apple Intelligence tools add a hidden SynthID watermark to images.
- It applies from version 27.2 on iPhone, iPad, Mac and Vision Pro.
- Real photos edited with Clean Up, Extend or Spatial Reframing are tagged too.
- Anyone can check an image by uploading it at synthid.com.
Which Apple Tools Add the Watermark
Apple names two groups of tools. The first group lives in Photos: Clean Up, Extend and Spatial Reframing. The second group covers the image makers, Image Playground and Image Wand.
Image Playground builds brand-new pictures from scratch, so most people would already think of its output as AI art. The bigger change is in Photos, where a normal snapshot becomes a tagged file after a single AI edit.
Apple says pictures you made or edited before installing the 27.2 updates do not carry the mark. An older image only picks up the watermark if you open it again and run one of the listed tools on it.
How the Hidden Mark Works
According to Apple, the watermark cannot be seen and does not change how a picture looks. There is no badge, corner logo or visible stamp on the image, on your screen or when you share it.
The tag can only be found with a SynthID detector. Apple points people to synthid.com, where you open the site in a web browser, upload an image and follow the steps to see whether a watermark is present.
Apple says the purpose is to help flag pictures that AI helped make or alter. The 27.2 software updates are already available, and the support page explaining the watermark followed this week.
What This Means for You
If you use Clean Up to erase a stranger from a vacation shot, that photo will now carry a hidden note that AI edited it. For most family pictures this makes no practical difference, since nothing visible changes.
It can matter more for people who sell photos, enter contests, or send images to news outlets, schools or employers that have rules about AI edits. A detector may flag your picture even if the edit was small, so it is smart to be upfront about using these tools.
Apple’s support page does not mention a setting to switch the watermark off. If you want a picture to stay free of the tag, the simple route is to skip the listed AI tools and make your changes with regular edits such as cropping, light and color.
The mark can also help you. When a surprising image lands in a group chat, uploading it to the detector is a quick way to check whether it came from one of these AI tools. Keep in mind that a missing tag does not prove a picture is real, because many other apps never add one.
How to Check Your Own Images
First, make sure you know which version you are running by opening Settings, then General, then About on an iPhone or iPad. The watermark only applies on version 27.2 or later.
To test a picture, export it from Photos, open synthid.com in your browser and upload the file. If your iPhone saved it in Apple’s HEIC format, our HEIC file viewer lets you preview it first, and the free image compressor can shrink large exports before you share them.
Conclusion
With the 27.2 updates, Apple now quietly tags images made or edited with several Apple Intelligence tools, including everyday Photos fixes like Clean Up. You will not see the mark, but a SynthID detector can, so it is worth remembering which edits leave this trace before you share a photo where AI rules apply.
