AI Image Metadata: What ChatGPT and Gemini Leave in a File
We downloaded images from ChatGPT and Gemini and read their metadata: a signed C2PA manifest and a declared invisible watermark. What each one contains.

A real example
What one photo gives away
This is the sample photo from the tool above. Nothing in the picture shows where it was taken, who took it or which camera was used, but its metadata records all three.
- Location to a few metres, from the GPS tags
- Your name in the Artist and Copyright fields
- The camera body, through its serial number

AI provenance
It reads AI provenance, and says where it stops
Generators and editing apps often record what they did in the file's metadata, and Pixvisor reads those records. An invisible watermark embedded in the pixels, such as Google's SynthID, is different: cleaning metadata neither detects nor removes it, and the report says so.

How it works
Three steps, under a minute
Your image travels over an encrypted connection, is processed on our server in seconds, and the temporary file is deleted right after. Read the methodology.
Drop a photo
Or paste an image URL. The file is read in a few seconds, every EXIF, IPTC and XMP field included.
Read the report
A privacy score, the sensitive fields called out, the GPS point, any AI trace, and the full list of tags.
Apply your changes once
Pick what to remove or edit. One click writes a new file; your original is never touched.

AI & provenance AI & provenance Can You Remove the Gemini Watermark? The Three Marks, Explained
Gemini images carry three marks: a visible sparkle, a C2PA record and an invisible SynthID watermark. Which ones you control, and which ones stay.

SynthID is the invisible watermark Google adds to content made with its AI. How it works, how to check an image for it, and why metadata tools cannot see it.
Frequently asked questions
Is Pixvisor free?
Yes. Viewing metadata, checking for AI traces and cleaning images are free, with no account and no limit on the number of photos you check.
Do my images get uploaded to a server?
Yes, briefly. Your image is sent over an encrypted connection, processed in seconds, and the temporary file is deleted immediately after analysis. Nothing is stored, logged or shared, and your original file on your device is never modified.
What metadata can it remove?
EXIF, IPTC and XMP, including GPS location, camera serial numbers, software tags, thumbnails, and AI generation fingerprints such as C2PA Content Credentials and Stable Diffusion parameters.
Can it detect AI-generated images?
It detects AI fingerprints in the metadata layer: C2PA / Content Credentials, IPTC digitalSourceType, Stable Diffusion and ComfyUI parameters, and the declared software. It cannot detect an invisible pixel watermark such as SynthID.
Which formats are supported?
JPEG, PNG, WebP, HEIC/HEIF, TIFF and GIF.
How do I remove EXIF data from a photo?
Drop the photo in the tool above and choose “Erase everything” (or the privacy preset to keep harmless fields). The dedicated Remove EXIF page does the same in one step. Your original file is never modified; you download a clean copy.
Does cleaning metadata change image quality?
No. Metadata is rewritten without recompressing the image, so the pixels are untouched; the ICC colour profile and orientation are preserved.
What's the difference between EXIF, IPTC and XMP?
EXIF is written by cameras and phones (settings, dates, GPS). IPTC is the press/agency standard (captions, credits, usage). XMP is Adobe's extensible layer that can mirror both and carries newer fields such as AI provenance. Pixvisor reads and cleans all three.
