Writes IPTC:DigitalSourceType into the file, the documented convention for provenance. PNG and JPEG only.
The transparency obligations under Article 50 of the AI Act have applied since 2 August 2026. The noise around them is louder than the rule itself, and most summaries online conflate two entirely different duties.
If you provide an AI system (Article 50(2)), you must mark the generated content in a machine-readable format, so that a machine can detect it as synthetic. That is the job of OpenAI, Adobe or Midjourney, not yours. It is handled by methods such as C2PA Content Credentials or invisible watermarks. A visible label does not satisfy this duty.
If you publish AI content (Article 50(4)), you must disclose that the content was artificially generated or manipulated. Here a clear, perceptible label is enough, and that is exactly what this tool produces. This is the case that applies to most companies, agencies and freelancers.
Paragraph 4 targets deepfakes, meaning image, audio or video material that resembles real people, places or events closely enough to be mistaken for authentic. An abstract AI pattern used as a background graphic does not fall under it. An AI-generated person who looks like a photo of your team certainly does.
People are no longer the only ones looking at images. Platforms, image archives and editorial systems read metadata, and one field has become the anchor for provenance: IPTC DigitalSourceType. This tool writes it into the file on request, matching the label you picked.
Three values matter here: trainedAlgorithmicMedia for images fully generated by a model, compositeWithTrainedAlgorithmicMedia for material that was edited using generative AI, and compositeSynthetic for composites in which AI parts are mixed with real ones.
The field is read reliably where images are managed rather than consumed: in image archives, editorial and asset systems, and by verification tools. It is the documented convention for provenance, and following it costs nothing.
With social platforms the picture is thinner than the announcements suggest. In an IPTC test from March 2026, Instagram and Pinterest did evaluate the field, LinkedIn reads C2PA instead, and TikTok and YouTube recognised nothing at all. What was tested, however, was material from Meta's own generator. Whether a field written after the fact by a tool like this one is treated the same way, that test does not say — and in practice users report that on upload only the manual toggle still takes effect. The IPTC itself calls the state of things “a work in progress”.
Hence both. The visible mark survives any re-encoding by a platform, the metadata field travels with the file wherever it is passed on unchanged. On its own, each has a gap. A crop, by the way, removes both — one just as reliably as the other.
The three symbols in this tool come from the official icon set the European Commission published in June 2026. They are free to use and require no attribution. Using them is optional, the labelling obligation itself is not. And the reverse holds too: using the icons does not by itself make you compliant. Responsibility for adequate disclosure stays with you.
Straight from the source: the Commission's EU icons and the wording of Article 50.
No. The disclosure obligation under Article 50(4) applies to deepfakes, meaning content that closely resembles real people, places or events. An AI-generated icon, an abstract texture or an obviously stylised illustration does not automatically fall under it. But as soon as an image could pass for a real photograph, you should label it. Regardless of the law, transparency towards your clients is the better position anyway.
For the deployer role, meaning you as a person or company publishing AI content: yes, a clear and perceptible label is exactly what paragraph 4 requires. For the provider role, meaning whoever offers the AI system: no. Paragraph 2 additionally requires a machine-readable marking, for example through C2PA Content Credentials. This tool deliberately serves the first case. If you are unsure which role you are in, that is precisely the question worth settling properly rather than guessing.
No. The tool is one HTML file and a bit of JavaScript. Your image is processed through your browser's canvas and handed straight back to you as a file. There is no upload, no temporary storage and no account. You can load the page, switch off your Wi-Fi and keep working. For traffic statistics a self-hosted Matomo runs along, counting page views and seeing nothing of your images.
No. The Commission published the three icons in June 2026 as a voluntary offer, free to use and with no attribution required. A plain text note such as “AI-generated” satisfies the disclosure just as well. The advantage of the icons is that they work across language barriers. The drawback: they are still new and many viewers do not recognise them yet. That is why you can choose either variant here.
