Questions
How does it know what my file is?
From the file's content, not its name — a photo renamed to ".txt" is still checked as a photo, and a file renamed to ".pdf" is not treated as a PDF. Formats this version does not check yet (Excel, PowerPoint, older Office files, RAW) are named as such and left unchanged, never reported as checked.
What does "not fully inspected" mean?
A part of the file we recognised but could not look inside — for example a page that is a picture, an unfamiliar block in a photo, or a drawing inside a Word document. What it contains is unknown, so it is never counted as checked.
Does this tool upload my files?
No. Everything happens in this browser tab; your files are never sent anywhere. For a PDF, the PDF reader and font data are downloaded from this site when you add it — never your file.
