# View Metadata
|
|
|
|
Examine the hidden properties embedded in a PDF file. The tool displays document information (title, author, dates), XMP metadata, page dimensions, and other structural data in a readable format.
|
|
|
|
## How It Works
|
|
|
|
1. Upload a PDF file.
|
|
2. The tool immediately parses the file and displays all available metadata in organized sections.
|
|
3. Review the document info dictionary, XMP metadata tree, and structural properties.
|
|
4. No processing step is needed -- metadata is displayed as soon as the file loads.
|
|
|
|
## Features
|
|
|
|
- Displays standard document info fields: Title, Author, Subject, Keywords, Creator, Producer
|
|
- Shows creation and modification dates in human-readable format
|
|
- Parses and renders the full XMP metadata tree with nested namespaces
|
|
- Handles PDF date format (`D:20240101120000Z`) conversion to readable dates
|
|
- Organized into collapsible sections for easy navigation
|
|
|
|
## Metadata Sections
|
|
|
|
| Section | Contents |
|
|
| ----------------------- | ------------------------------------------------------------------------------------- |
|
|
| **Document Info** | Title, Author, Subject, Keywords, Creator, Producer, Creation Date, Modification Date |
|
|
| **XMP Metadata** | Full XML-based metadata tree with Dublin Core, XAP, PDF, and custom namespaces |
|
|
| **Document Properties** | Page count, PDF version, file size, encryption status |
|
|
|
|
## Use Cases
|
|
|
|
- Checking who authored a PDF and when it was last modified
|
|
- Verifying that metadata was properly set before publishing a document
|
|
- Auditing PDFs for privacy by checking what personal information is embedded
|
|
- Investigating the software used to create or modify a PDF (via the Producer field)
|
|
- Reviewing XMP metadata for digital asset management compliance
|
|
|
|
## Tips
|
|
|
|
- PDF date strings that start with `D:` are automatically converted to your local timezone format.
|
|
- If metadata fields appear empty, the PDF creator simply did not set them. Not all PDFs contain rich metadata.
|
|
- To modify metadata after inspecting it, use [Edit Metadata](./edit-metadata). To strip it entirely, use Remove Metadata.
