PDF Metadata Viewer

Select a PDF file and instantly see its title, author, subject, keywords, producer, creator, creation and modification dates, and page count. The file is processed locally with pdf-lib and never uploaded to any server.

How it works

  1. Select a PDF file from your device using the file picker.
  2. Your browser reads the file as binary data, and pdf-lib extracts the document information (the document info dictionary).
  3. The title, author, subject, keywords, producer, creator, dates, and total page count are displayed.
  4. If the PDF is corrupted or not a valid file, a clear error message is shown instead of incorrect data.

Use cases

  • Verify who authored a PDF or which tool generated it before reusing it.
  • Check the actual creation date or last-modified date of a document.
  • Quickly audit the metadata of PDFs received from third parties before sharing them.
  • Check whether a PDF retains sensitive metadata (author, software used) before publishing it.
