How it works
Drop a PDF and this viewer reads its internal structure straight away: the PDF version from the file header, the page count, the media box of every page (converted to points and millimetres, with common names like A4 or Letter detected automatically), the rotation flag, whether the document is encrypted, whether it carries an interactive AcroForm, and the document information dictionary — title, author, subject, keywords, creator, producer and the creation and modification dates.
Everything is parsed in your browser with the File API and the pdf-lib library, so the document is never uploaded and nothing is stored. Dates are shown in UTC exactly as the PDF records them, so the same file always reports the same timestamps. Copy the full report to the clipboard or download it as a plain-text file for your records. A password-protected PDF still reports its structure, but the document properties may be unreadable until you unlock it.
Frequently asked questions
Does this PDF info viewer upload my file?
No. The PDF is read with the File API and parsed in your browser by the pdf-lib library, so the document never leaves your device and nothing is stored or sent to a server.
How do I check the page size of a PDF?
Drop the PDF here and the page details table lists every page with its media box in points and millimetres, the detected paper name (A4, Letter, Legal, Tabloid and more), the orientation and the rotation flag. If the pages differ, the summary shows how many distinct sizes the document uses.
Can it open a password-protected PDF?
It still reports the structural facts, namely PDF version, page count, page sizes and that the file is encrypted, but the document properties of an encrypted PDF may be unreadable. Unlock the file in your PDF reader, save a copy, then load that copy for the full report.
