Inspect all of an image's metadata

The EXIF viewer answers a specific question about a photograph: which camera, when, and where. This tool answers a broader one about any image file: what blocks of data exist in it at all. It is the right place to start if you are checking a file that came out of Photoshop, a scanner or a content management system rather than a camera.

XMP is an XML block that Adobe introduced and most editors now write. It typically holds captions, keywords, ratings, copyright statements and a history of the edits applied to the file. Because it is designed to survive editing, it often outlives the EXIF a user thought they had removed.

An ICC profile tells software how to interpret the file's colour values so that the same image looks consistent across screens and printers. It contains no personal information. Removing it makes the file slightly smaller but can visibly shift colours, so this tool keeps it unless you explicitly ask for it to go.

Because those are different statements and conflating them would be dishonest. If the tool has not been taught to read metadata inside a particular container, it says so. Reporting 'no metadata found' for a format it never examined would give you a false all-clear on exactly the file you were worried about.

Yes. Steganography can hide data in the pixels themselves, and some formats allow vendor-specific blocks this tool reports only as 'other'. This tool is a thorough reader of standard metadata containers, not a forensic analysis, and it does not claim to be one.
