Upload any PDF to check its page count, dimensions, PDF version, security status, and document metadata - read-only, your file is never modified.
PDF Inspector reads a PDF file and reports what is really inside it: PDF version, page count, page dimensions, whether it is password-protected or encrypted, and its document info fields (Title, Author, Subject, Keywords, Creator, Producer, and creation/modification dates). This is a read-only tool - your file is parsed to extract this information and is never modified, so there is no risk to the original document. It is part of a small, honestly-scoped set of PDF tools built without any external PDF library or server binary.
