What is PDF Metadata Viewer?
Every PDF document carries an internal dictionary of structural properties, known as the document information dictionary, which remains invisible during normal reading. This utility instantly parses that hidden data structure, allowing you to examine the file's origin and history without needing expensive desktop publishing software. By extracting these raw attributes, you can easily discover the exact date and time the file was originally generated, identify whether it was exported from Microsoft Word, Adobe Illustrator, or a basic scanner, and see any keywords or author names permanently embedded in the file. It is an essential step for verifying document authenticity or auditing files before publishing them online.

Frequently Asked Questions
Yes, the dashboard displays both the original created timestamp and the modified timestamp. If the dates differ, the file has been altered or re-saved since its original generation.
Not all software automatically populates every property when exporting a file. If the original author did not specify a title, subject, or keyword list, those specific dictionary entries simply will not exist in the file.
The creator is usually the original application where the document was designed (such as Microsoft Word or Adobe InDesign), while the producer is the specific engine or library that converted that design into the final file format (such as macOS Quartz or Acrobat Distiller).
No, this utility operates strictly in read-only mode. It parses the internal dictionary to display the information but makes absolutely zero modifications to the file structure or contents.
The tool reads the raw timestamp string embedded in the file's structure. If the originating software included a timezone offset in that string, the result will reflect that specific offset, which may differ from your current local time.
Absolutely. The parsing logic operates completely locally on your device. We do not transmit or store your documents on any external servers.
