How PDF Metadata, Page Count & Encryption Inspector (Browser-Local Parser) Works & When to Use It
Inspect basic PDF header, page-object and encryption markers locally. Preview simple uncompressed text. Results are estimates, not a complete PDF validation. Calculations and file processing run in this browser tab. The tool does not send working inputs or files to our hosting server.
Step-by-Step Instructions
- Choose a PDF, or paste a small PDF sample to explore the example.
- Review the detected version, page markers, metadata and encryption indicators.
- Treat these as parser observations, not proof of authenticity or a complete security inspection.
Worked Examples

PDF v1.4 | 1 Page(s) | Unencrypted (Readable) |
| Detect Encrypted / Password-Protected PDF Dictionary | {"rawPdfSample": "%PDF-1.7\n1 0 obj\n<< /Type /Catalog /Pages 2 0 R >>\nendobj\n2 0..."} |
PDF v1.7 | 3 Page(s) | Encrypted (Password Protected) |

Important Limitations & Edge Cases
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.
