When people ask whether an image is AI-generated, one of the first places to look is its metadata: the hidden information stored inside the file. Here is what that can include, why it is not reliable on its own, and how to check it.
If you publish AI images yourself, this also helps you understand what you may be sharing without realizing.
Key Takeaway: Metadata is a clue, not proof. Its presence can point to a generator; its absence means only that it is missing, not that the image is real.
What Metadata Can Be in an Image File
- EXIF: camera model, date, settings, GPS location and the software that last saved the file.
- XMP: extensible fields that editing and generation tools may use, including creator tool names.
- PNG text chunks: some tools store generation details, such as prompts, in these fields.
- Content Credentials (C2PA): a signed record, attached by some tools, describing how an image was created or edited.
Which of these appear depends entirely on the tool that made the file.
Why Metadata Disappears
Screenshots create a brand-new file with no original metadata. Many social platforms and websites strip or rewrite metadata on upload. Editing, resizing and exporting from some apps removes it too. That is why a missing tag cannot show an image is human-made, and why detection tools treat metadata as one signal among several (see are AI image detectors accurate?).
How to Check an Image's Metadata
- Use the original file, not a screenshot or re-download, if you can.
- Run it through the AI Image Detector, which reads metadata signatures for known generators in your browser.
- Check the file's properties on your computer to see EXIF fields.
Privacy and Honesty When You Publish
Metadata can include more than you intend, such as location in photos or prompt text in some AI files. If you do not want to share it, remove it with the EXIF remover (see how to remove EXIF data).
Note: Removing metadata is a privacy step, not a way to hide how an image was made. If you publish AI-generated images, follow the disclosure rules of the platform or client you are publishing for.
Frequently Asked Questions
Do AI-generated images have metadata?
Some do. Certain generators write software names or generation details into the file, and some attach Content Credentials. It varies by tool and by what has happened to the file since.
What are Content Credentials (C2PA)?
A signed record some tools attach to describe how a file was made or edited. They can be removed when a file is re-saved or processed by some platforms, so they are not always present.
Does missing metadata mean an image is real?
No. Screenshots, re-saving and platform uploads strip metadata from all kinds of images, including AI ones.
How can I see an image's metadata?
Use the file's properties on your computer, or an online metadata viewer or detector. TinyPNG Now's AI Image Detector reads it in your browser.
Should I remove metadata before sharing an image?
For privacy, yes, especially location and any embedded prompts. Just remember removing it does not change that an image is AI-generated.
Summary: Metadata can hint at how an image was made, but it is easy to lose. Check it with the AI Image Detector, clean it with the EXIF remover for privacy, and be open about AI use.
