This old question "Is EXIF data removed from uploaded SE pictures?" claims that
Imgur will strip the EXIF data once the image is uploaded to their server
Recently, a question posted on the new GenAI beta site demonstrated that:
The two frontends I'm aware of that store metadata in generated images do so in PNG text chunks, which are preserved so long as the image doesn't go over the limit where it gets JPEG'd
For reference, this is the image SirBenet posted there.
In this example, metadata about the used prompt is preserved.
It is therefore clear that multiple type of metadata exist and while some are removed when an image is uploaded some are not.
Based on my experience, I had also noticed that uploading an image in the chat interface does not work in the same way of uploading an image on the site: at the very best, some of the size limits are different between the two interfaces (I think that the chat ignores the 2 MB maximum size limit).
For this reason, I am asking the staff if they could confer with Imgur to confirm what is the actual current implementation and post the relevant information here.

chunk. It's likely that when Imgur says they removeeXIf
, they mean it, and they don't touch anything else.
