contains-synthetic-performer tag tool: free batch tagging

Amazon asks sellers to tag listing images that show a photorealistic person generated by AI. Drop in your images and get them back tagged — as many as you like, in one go.

Free. No sign-in, no credits — and your images never leave your browser.

Adds the keyword contains-synthetic-performer to each image’s XMP dc:subject, the same as exiftool -XMP-dc:Subject+=contains-synthetic-performer. The picture itself is not re-saved, and keywords already there are kept.

Which images need the tag?

Tag these

A model, hand or family made entirely by AI — wearing, holding or using your product
An AI lifestyle scene with a photorealistic person in it

These don’t need it

Real people you photographed, even if AI edited the picture afterwards
Images with no people in them — product shots, white-background images
People who are clearly not photorealistic: illustrations, cartoons, icons

Going by Amazon’s guidance to sellers. The rule is Amazon’s and can change — check Seller Central’s help for the current wording before you rely on it.

How it works

Step 1
Add your images
Drop or choose any number of JPEG or PNG files. They are read on your device; nothing is uploaded.
Step 2
Each one is tagged
The keyword contains-synthetic-performer is added to its XMP dc:subject. A file that already has it is left as it was.
Step 3
Download and upload to Amazon
Download each file, or all of them as one ZIP, with the original names — then upload them as usual.

Questions

What is contains-synthetic-performer?: It is the keyword Amazon asks sellers to add to the metadata of an image that shows a photorealistic person generated by AI. Amazon reads it from the image’s XMP dc:subject field and can tell shoppers that the image contains a synthetic performer.
Which images need it?: Images with a photorealistic person who was generated by AI. Photos of real people — even ones edited with AI — and images with no people do not, going by Amazon’s guidance to sellers. The rule is Amazon’s and can change: check Seller Central’s help for the current wording. This tool adds the tag to whatever you give it; deciding which images need it is up to you.
Does it change or compress my images?: No. The tag is written into the file’s metadata; the picture data is copied through unchanged, so quality and dimensions stay exactly the same. The file grows by a few hundred bytes.
Are my images uploaded anywhere?: No. Everything happens in your browser, on your device. Nothing is sent to us or anyone else, which is also why it is free and needs no sign-in.
What about keywords already in my files?: They are kept. The tag is added alongside your existing keywords and metadata, the same as running exiftool -XMP-dc:Subject+=contains-synthetic-performer. A file that already carries the tag is not changed.
Can I check whether an image is already tagged?: Yes — add it. The list shows “Already tagged — unchanged” for any file that already carries the keyword.
Which formats work?: JPEG and PNG, the formats Amazon listing images use. Other formats are listed as not taggable and left alone.
