How the PDF Page Info tool works
The PDF page info tool extracts metadata and page dimensions from any PDF file without uploading it to a server. Drop your PDF to instantly see page count, file size, PDF specification version, document properties (title, author, creator application, creation date), encryption status, and the exact dimensions of every page in points, millimetres, and inches — all processed client-side in your browser for complete privacy.
PDF metadata fields
PDF documents carry an embedded metadata dictionary with fields including Title, Author, Subject, Keywords, Creator (the application that created the source document), Producer (the PDF rendering engine), CreationDate, and ModDate. These fields are set by the authoring application (Word, InDesign, LibreOffice) and can reveal information about the document's origin. The tool displays all present fields and flags absent ones that you may want to populate before sharing a document professionally.
Page dimensions and MediaBox
Every PDF page has a MediaBox that defines its physical dimensions in points (1 point = 1/72 inch). A standard A4 page is 595×842 points (210×297 mm). A US Letter page is 612×792 points (215.9×279.4 mm). The tool displays dimensions in points, millimetres, and inches alongside the named page size (A4, Letter, Legal) when the dimensions match a standard. Unusual dimensions indicate custom page sizes, which is useful to know before sending to a commercial printer.
Mixed-size and rotated pages
Documents produced from multiple sources often mix page sizes — cover pages at A4, appendices at Letter, or oversized drawings at A3. The tool groups pages by unique dimensions so you can identify which pages deviate from the dominant size. Page rotation (landscape pages embedded in a portrait document via a Rotate entry in the page dictionary) is displayed separately from physical dimensions, revealing whether a "landscape" page is actually rotated in the PDF vs natively wide.
Encryption and access permissions
Password-protected PDFs use RC4 or AES encryption. The tool detects the encryption flag and reports whether the document is open-password protected (requires a password to view), owner-password restricted (can view but not print, copy, or edit without the owner password), or unencrypted. Permission flags stored in the PDF determine whether printing, copying, and form filling are allowed. Understanding these settings is important before automating PDF processing in a workflow pipeline.
PDF version and compatibility
PDF specification versions range from 1.0 (1993) to 2.0 (2017, ISO 32000-2). Most documents are PDF 1.4 to 1.7. PDF 2.0 introduced improved support for accessibility and digital signatures. The version number affects which features are available: transparency (PDF 1.4+), layers (PDF 1.5+), 3D content (PDF 1.6+). Knowing the version helps diagnose compatibility issues when processing PDFs with older tools or embedding them in enterprise document management systems.
Frequently asked questions
- What metadata can this tool read from a PDF?
- The tool reads standard XMP and document information metadata fields: Title, Author, Subject, Keywords, Creator (the application that originally created the source document, such as Microsoft Word), and Producer (the software that generated the PDF file, such as Adobe Distiller). Not all PDFs contain metadata — many PDFs exported by web tools, browsers, or quick-export functions have empty or minimal metadata fields.
- What do the page dimensions in points mean?
- PDF page dimensions are stored internally in points (pt), where 1 point equals 1/72 of an inch (approximately 0.353 mm). An A4 page is 595 × 842 points, which equals 210 × 297 mm. A US Letter page is 612 × 792 points, which equals 216 × 279 mm. This tool displays both the native point dimensions and the equivalent millimetre dimensions for each page.
- Why does my PDF show inconsistent page sizes?
- Some PDFs intentionally mix page sizes. For example, a professional report may have an A3 landscape cover page followed by A4 portrait body pages. Presentation PDFs exported from PowerPoint or Keynote typically use widescreen dimensions (960 × 540 pt or 1280 × 720 pt equivalent). This tool groups all pages by their unique dimensions so you can quickly identify which pages use which size.
