Platform comparison

How Instagram, TikTok, LinkedIn and Pinterest Label AI Images

Each platform decides for itself when to call an image AI-generated. Some read C2PA Content Credentials, some read the IPTC digital source type, some run their own classifiers, and all of them rely on creators to disclose. This page compares what each one reads, and links to a guide for each.

What each platform reads

Metadata signals are the ones a cleaner can change. Watermarks, classifiers and your own disclosure are not.

“Sometimes” marks cases where the platform's statement and independent tests disagree, or where behavior depends on the upload path. Reviewed September 25, 2026.

Three kinds of signal

Metadata signals are the IPTC digital source type and C2PA manifests written by the tool that made or edited the file. They are easy to read and easy to lose: any re-encode drops them. Watermarks sit in the pixels and survive screenshots and compression. Classifiers judge an image by how it looks. On top of these, every major platform asks creators to label realistic AI content themselves.

That is why removing metadata can change an automatic label caused by an editing tool, but does not change a platform's rules. If your content is AI-generated and the platform asks you to disclose it, you still need to.

What changes in 2027

From 1 January 2027, California requires large online platforms to detect and display standards-compliant provenance data on uploads and not to knowingly strip it. Expect more platforms to show Content Credentials the way LinkedIn does, and to note when a file that should carry them does not.

The privacy side of uploads

Most large platforms strip EXIF and GPS from the copy the public sees, but they still receive the original file. Messages, document uploads and marketplace listings often keep metadata intact. Cleaning a file before you upload it is the only way to be sure your location and device details stay with you.

Questions

Which platforms show Content Credentials to viewers?

LinkedIn shows a CR icon and a details panel on images and videos with C2PA credentials. TikTok and Meta use C2PA to apply their own AI labels rather than showing the credential itself.

Does removing metadata stop AI labels?

It removes the metadata signals only. Platforms also use watermarks, classifiers and your own disclosure, and their rules on labeling realistic AI content still apply.

Do platforms remove my photo's location?

Instagram, Facebook and public LinkedIn posts do not show EXIF or GPS to other users, according to independent tests, but the platform still receives the original upload. Clean the file first if you do not want to hand over that data at all.
