What the file carries under the page
A PDF's structure can carry more than its pages render. This reads that structure in your browser and reports what the file instructs, with the evidence beside every statement.
This reads the file's own structure and reports what it instructs.
It does not scan for viruses, audit security, or make any claim about the file's safety. It reaches no verdict on the document or its author.
