About this tool
Inspect basic PDF header, metadata, page-object and encryption markers inside this browser. This lightweight marker inspection is useful for an initial look, while a full PDF viewer remains the right place to confirm important document properties.

FAQs
Can this decrypt a PDF or perform OCR?
It cannot decrypt documents or perform OCR. Compressed objects, incremental updates and unusual PDF structures can also produce incomplete observations. Confirm page counts and encryption results in a trusted viewer.
Which inputs do I need for PDF Metadata, Page Count & Encryption Inspector (Browser-Local Parser)?
Use PDF Source Stream (or upload any .pdf file below). The built-in examples show how those fields fit together.
What should I check before using this result?
This is a basic marker-based inspector, not a full PDF parser or security check. Compressed object streams, incremental updates and unusual PDFs can give incomplete or inaccurate page counts and encryption results. It cannot decrypt files, perform OCR or extract most compressed/encoded text. Confirm important results in a trusted PDF viewer. Keep the original file. Check the saved format, dimensions, page order and content before replacing or sharing a document.
