iOS 27.2 adds Google's SynthID invisible watermark to Image Playground images and some Apple Intelligence photo edits

Apple has switched on SynthID watermarking in iOS 27.2. Every Image Playground image carries it, as do Photos edits made with Extend and Reframe; Clean Up adds it only for larger edits, per MacRumors' tests. SynthID, built by Google, embeds the mark in pixels. The iPhone has no detector; images must be checked on Google's SynthID Detector site.

Why it matters

By adopting Google's SynthID instead of its own scheme, Apple makes AI-made and AI-edited iPhone images detectable by outside tools, widening SynthID's reach.
