Why your real photo got labeled as AI.

Where the signal comes from

Platforms label images when the file says it was made or changed with AI. Meta, for example, reads C2PA and IPTC metadata (Meta) and notes that if a photo editing tool "uses AI to change the size or color of an image, then the image may have a signal that shows it was edited using AI" (Meta Help Center). The question is which apps write that signal. Here is what the companies themselves say:

Not every Content Credentials manifest says "AI". A Pixel 10 photo carries credentials because it was captured by a camera, which is evidence for authenticity, not against it. What matters is what the manifest or the IPTC field claims, and that is what the report above shows.

Generated, edited or composite: how the label differs

Meta separates content "created with AI", which is labeled "AI content" on the post, from content "modified using AI", which does not get the label directly on the post, story, reel or thread (Meta Help Center). In the file this usually shows up as two IPTC values:

• trainedAlgorithmicMedia: the whole image was generated.
• compositeWithTrainedAlgorithmicMedia: part of a real image was changed with AI.

If your photo shows the first value but you only removed a sign from the background, something in your editing chain recorded the edit more strongly than it deserves. That is exactly the case removing metadata is meant for.

Fix it before you post

1. Drop the final exported photo into the box above.
2. Read the report: C2PA manifest, IPTC AI source flag, the tools mentioned, plus GPS and device data.
3. Download the cleaned copy and post that. The image data is copied byte for byte, so the photo looks exactly the same.

A label that is already on a published post won't change when you clean your file; post the cleaned copy as a new post if you need to.

A checklist for photographers

• Note which tools you used. A generative remove or fill leaves a different signal than a color or exposure change.
• Check the final export, not the RAW file or an earlier version, because exporting can add or drop metadata.
• Look at the AI source line: "AI-edited (composite)" means the file claims a partial AI edit, "AI-generated" means it claims the whole image was generated.
• Keep a signed or untouched original archived before you share a cleaned copy.

When cleaning won't help

• Some AI editors also add an invisible watermark to the pixels. Google applies SynthID to images edited with Reimagine in Google Photos (Google), and Samsung overlays a visible watermark on images generated with some Galaxy AI features (Samsung). Neither is metadata.
• If you disclosed AI use when posting, the label comes from your choice, not the file.

Keep your original. If your camera or phone signs photos with Content Credentials, that record can later prove a picture is real. Share a cleaned copy where provenance doesn't matter, and keep the signed original as your evidence.
