Add images to inspect their metadata and apply the Amazon tag.

This tool adds metadata only. It does not decide whether an image contains an AI-generated person.

01

What is contains-synthetic-performer?

Amazon’s product image guidance says images with photorealistic people generated entirely by AI must include a disclosure tag before upload. The exact keyword is stored as hidden metadata in the image file, not drawn as a watermark.

02

When should you add the Amazon AI person tag?

Add the tag

  • The image contains a photorealistic person.
  • That person was generated entirely by AI.
  • The person is fictional and is not based on a real person.

Do not add the tag

  • The image only contains real people, even if AI tools altered it.
  • There are no people in the image.
  • The people are illustrated, cartoon, or otherwise non-photorealistic.
  • The image only shows characters from a movie, game, or expressive work.

05

Image, text, claims, and awards

A+ images and text should be unique to the A+ experience instead of repeating the product image gallery. Use one brand logo and only useful navigation icons.

Amazon asks creators to spell out numbers under ten, use consistent punctuation, capitalize major words in headings, and avoid all-caps copy, repeated information, and unnecessary font styling.

Awards and endorsements should identify the granting organization and date, and awards older than two years should not be used. Certification, testing, approval, and environmental statements require suitable substantiation.

Satisfaction guarantees, #1 claims, top-rated claims, best-selling claims, and unsupported health or disease claims can result in rejection.

Amazon AI image metadata FAQ

Does every AI-generated image need the tag?

No. Amazon’s guidance focuses on images featuring photorealistic people generated entirely by AI. AI backgrounds, AI products, images with no people, and non-photorealistic people do not meet that specific condition.

Is contains-synthetic-performer a visible watermark?

No. It is an invisible keyword stored in the image’s XMP metadata. Amazon may use it to display a disclosure where applicable.

Where is the keyword stored?

It is stored as an item in the Dublin Core dc:subject RDF Bag inside the XMP packet.

Does the tool change image quality or dimensions?

No. It edits the JPEG APP1 or PNG iTXt metadata container without decoding and re-encoding the compressed image pixels.

Will existing XMP keywords be removed?

No. The tool appends the Amazon keyword. If existing XMP cannot be modified safely, that file stops with an error rather than replacing the packet.

Are files uploaded to a server?

No. Reading, tagging, verification, and ZIP creation all happen locally in your browser.

Can this tool decide whether a person was generated by AI?

No. The decision depends on how the image was created. The tool writes metadata to the files you select and does not classify image content.
