About PDF Info Viewer — Free Online Tool
PDF Info Viewer reports what is inside a PDF: its version, page count, document properties, form field count, and the exact size of every page.
The version is read from the %PDF- header in the raw bytes, which it will still find when junk has been prepended to the file, and the rest comes from the document catalogue: title, author, subject, keywords, creator, producer, both dates, whether the file is encrypted, and how many interactive form fields it holds. Page geometry is listed per page in points and in millimetres, with the rotation applied and whether it sits portrait or landscape — which is how you catch the one A3 sheet hiding in an A4 document. Encrypted files are opened read-only so they can still be reported on. What it does not do is list embedded fonts; nothing here inspects the font resources.
The report is produced in the browser and offered to you as a JSON download; the file is not uploaded to be inspected.
Working out why a print shop rejected a file for mixed page sizes, checking whether a PDF is encrypted before trying to edit it, confirming a form really has fillable fields, and reading the producer string to see which software made a document.

When to use it
Finds the one odd-sized sheet a print shop rejected a file over, and tells you whether a document is encrypted before you try to edit it.
How it works
The version comes from the %PDF- marker in the raw bytes; everything else is read from the document catalogue and the page tree.
Fonts Are Not Inspected
Nothing here opens the font resources, so there is no list of embedded TrueType or Type 1 faces and no subsetting check. Nor are the individual security permissions read — the report says only whether the file is encrypted, and an encrypted file is opened read-only so it can still be described.
Page Geometry Page by Page
Each page is listed in points and in millimetres, with its rotation and whether it sits portrait or landscape, measured from the media box.
