iPhone AI Images and Edits Now Carry Hidden SynthID Watermark

iOS 27.2 enables SynthID support: images from Image Playground and some Apple Intelligence edits now get a pixel-level watermark. The Google-made tool is designed to survive cropping, filters and compression without hurting quality. There is no way to detect the watermark on iPhone itself — users must use the SynthID Detector website.

• SynthID is live in iOS 27.2 for Image Playground and Apple Intelligence edits
• The watermark is applied at pixel level and survives cropping and compression
• Small Clean Up edits get no watermark; larger ones do
• Detection requires the SynthID Detector website, not the iPhone
