When you'll go to download the image, it will offer an SVG and a PNG version that both have the metadata.

In the case of SVG, it's literally `(signature)...` right after the tag. In the case of PNG, it's stuffed as a `caBX` chunk.

To declaw these files, you can ask in your CLAUDE.md to run `exiftool -jumbf:all=` (for jpg & png), and to simply directly remove the tag in SVG files. I haven't looked at video files yet.
