AI Image Checker
See whether an image says it was made or edited with AI. The checker reads Content Credentials and AI labels hidden in the file.
Runs in your browser. Your data is never sent to a server.
How to use the AI Image Checker
Add the image
Drop a JPG, PNG, WebP, HEIC or AVIF file, or paste a screenshot. It is read on your device.
Read the result
You see whether the file declares AI generation or AI editing, which tool created it and who signed its Content Credentials.
Check the details
Open the Content Credentials, AI settings and full metadata to see exactly where each label comes from.
Why use this tool
More and more AI image tools label their output. OpenAI and Adobe Firefly attach Content Credentials, a signed record based on the open C2PA standard that states how an image was made. Other tools write an IPTC “digital source type” such as trainedAlgorithmicMedia, and local generators like AUTOMATIC1111 and ComfyUI save the full prompt and model settings inside the PNG.
This checker reads all of these labels in your browser and explains them in plain language. It does not guess from the pixels. That makes the answer reliable when a label is present, but it also means an image without labels cannot be proven real: metadata is easy to remove, and many apps and social networks strip it when a picture is uploaded or screenshotted.
Frequently asked questions
How do I check if an image is AI-generated?
Drop the image here. If the file contains Content Credentials, an IPTC AI label or generator settings, the checker shows it. If nothing is found, look for the original source and use a reverse image search, because labels are often removed.
Can this tool detect every AI image?
No tool can. This checker reads labels written into the file, which is reliable when they exist. Pixel-based “AI detectors” estimate a probability and often get it wrong, especially with edited or compressed images.
What are Content Credentials (C2PA)?
A standard for attaching a signed history to a file: which app or camera made it, what edits were applied and whether AI was used. It is backed by Adobe, Microsoft, Google, OpenAI and camera makers.
Why does my AI image show no labels?
The label was removed. Screenshots, many social networks, messaging apps and some editors re-save images without metadata. Some generators also use invisible watermarks, such as Google’s SynthID, which cannot be read from the file metadata.
Are my files uploaded to a server?
No. formatmath converts files with code that runs inside your browser. Your files are never uploaded, stored or seen by us.
Is it free?
Yes. There is no watermark and no daily limit. An account is optional and only keeps a history of your conversions.
