Check image origin
Check provenance labels (Content Credentials) in your browser — no upload.
No label does not mean real: labels are often lost when editing or taking a screenshot.
What the result means
- A found label shows the signer’s claims; we check the signature technically, not whether the claims are true.
- We give no warranty for the result.
- The result is not evidence and is not for legal use.
Your file stays on your device. It is only read in your browser, never uploaded and never stored. For the label check the page loads a checking module of about 3 MB from our server the first time.
What is checked?
- Content Credentials (C2PA): a digitally signed provenance label. It can name the software that created or edited the image and whether AI was involved.
- Metadata: fields such as IPTC “Digital Source Type” (for example “trainedAlgorithmicMedia” for AI), the software field in EXIF and XMP, and descriptions.
- Generator fields in PNG files, as written by some Stable Diffusion interfaces.
Invisible watermarks such as SynthID and the picture content itself are not checked. The services further down cover that.
Technology: the open-source library c2pa-web by the Content Authenticity Initiative (MIT licence) and the official C2PA trust list (CC BY 4.0), both hosted on our own server. Licences
How do I spot AI images, AI videos and deepfakes?
No single trick always works. Combine several checks.
Look closely
- Hands, teeth, ears, text and shadows: common AI tells, though newer models make them less often.
- A flawless image is not proof it is real.
Source and labels
- Reverse-image search (Google Lens, Bing, TinEye) and check who published it first.
- Content Credentials and platform labels help but are often missing — real images usually have no label either.
What about AI text?
We deliberately do not offer a text detector. Such tools are often wrong and can wrongly accuse people, such as students or job applicants. There is currently no freely available, reliable check for text.
External checking services at a glance
These services check things we cannot check in the browser, such as invisible watermarks. Sorted alphabetically, no ranking. No affiliate links, we earn nothing from them.
With these services, the provider processes your file under its own rules. Read its privacy notice first.

- Checks
- Checks images and audio for OpenAI provenance signals: C2PA label and SynthID watermark.
- Access
- Web tool by OpenAI.
- Limits
- Only detects content from OpenAI tools (ChatGPT, Codex, API). No match does not rule out OpenAI.
-
SynthID Detector Google DeepMind
- Checks
- Looks for SynthID watermarks in images, videos and audio from tools by Google and partners such as OpenAI, NVIDIA and Kakao (Apple soon, according to Google).
- Access
- Free, sign-in with a Google, Apple or OpenAI account. According to Google about 10 checks per day, interface in English.
- Limits
- Only detects SynthID watermarks. Content from other AI providers goes undetected.

Frequently asked questions
What does this page check?
It reads origin labels (Content Credentials) and simple metadata from your file. They show whether a program has marked the file as AI-generated or edited.
Is my image uploaded?
No. The file is read only in your browser, not uploaded and not stored.
Does “no label” mean the image is real?
No. Labels are often lost when a file is edited or screenshotted. The page does not check invisible watermarks or the image content itself.
