What this tells you
From August 2026, EU law requires companies that make generative AI tools to label what those tools produce, in a way software can read. This checks whether a picture carries that label.
Drop in a picture and you get three answers, in plain words:
- Does the file say AI made this picture? Some pictures carry a hidden note from the tool that made them. This says whether yours does.
- Can that label be trusted? A label can be checked, the way a signature on a document can. This says whether it holds up.
- Will the label survive being shared? Most websites strip it off when you upload. This says how likely that is.
This is not an AI detector. It never looks at the picture itself — only at the information attached to the file. A picture with no label may still have been made by AI. Most are.
Behind those three answers are ten checks on the file. What each one asks, and why it matters.
FAQ
It says “not labelled”. Does that mean the picture is real?
No, and this is the most important thing to understand about the answer. “Not labelled” is a fact about the file, not about the picture. Most AI tools still do not add a label at all, and most websites strip the label off when you upload an image. So an unlabelled picture is completely normal, and tells you nothing either way about whether AI made it.
Then what is this actually useful for?
A “yes” is worth a lot: it means the file itself carries a signed statement that AI made the picture, and that statement checks out. That is hard to fake. A “no” is worth knowing if you are the one publishing the picture — because from August 2026, EU law expects AI tools to add that label, and this tells you whether yours did.
Can this detect AI images?
No. Nothing here looks at the picture itself. There are tools that guess whether an image looks AI-made, and they are wrong often enough that we would rather not add to the pile. This reads the label a file carries, or reports that it carries none — which is a question that has an actual answer.
What happens to the picture I upload?
It is read, checked, and thrown away — within a second or two, before you see the result. It is never saved to disk, never stored and never logged, and neither is its filename. What we do keep is a tally: that a check happened, when, what the answer was, the file's format and size, and how long it took. That is how we know whether anyone is using this and whether it still works. It is not enough to identify you or to find your picture again. The only other thing this site stores is an email address, and only if you type one in.
The picture I made with AI came back unlabelled. Did I do something wrong?
Probably not. Most AI image tools cannot add this label yet. If yours can, the setting is usually called “Content Credentials” or “C2PA”. And even when a tool does add it, saving the picture again, resizing it, or uploading it somewhere usually removes it.
It passed here, then failed somewhere else. Why?
Because the label lives in the hidden information attached to a file, and almost everything that touches an image throws that away. A resize, a re-save, a screenshot, or an upload to most websites removes it, and nothing can bring it back afterwards.
Why only pictures?
This first version handles JPEG, PNG, WebP and AVIF images, which is what it has been properly tested against. Sound and video work in much the same way, but shipping them untested would be guessing. If you need them, say so in the form.
Need more than one at a time?
This checks one picture at a time, and it cannot add a label to a picture that has none. If you need to check a lot of files at once, or you need your own pictures labelled, leave an address and I will tell you when that exists. Nothing else, no list.
