PDF Metadata Viewer
The PDF metadata viewer shows what a PDF says about itself: title, author, subject, keywords, the program that created it, creation and modification dates, page count, page size and PDF version. Check a file before you publish or share it, and see whether it carries details you did not mean to include.

What PDF metadata is
Every PDF has a small “document information” section stored next to the visible pages. Programs such as Word, InDesign, Google Docs or a scanner fill it in automatically when they save the file. Search engines, file managers and PDF readers use it, for example to show a title in the browser tab.
Fields explained
| Field | What it tells you |
|---|---|
| Title | The name shown in the browser tab or reader title bar. Often blank or the original file name. |
| Author | The person or account name from the program that made the file. |
| Created with | The application that produced the original content, such as Microsoft Word. |
| PDF producer | The library or printer that turned it into a PDF, such as “Microsoft: Print to PDF”. |
| Created / Modified | Timestamps written by the software, shown here in UTC. |
| PDF version | The version number in the file header, for example 1.7. |
| First page size | Converted from PDF points (1/72 inch) to millimetres, with the paper name when it matches A4, Letter and similar. |
Why it matters
- Privacy: author names and software details can reveal more than you intend when you publish a document.
- Accessibility and SEO: a proper title helps screen readers and search results.
- Record keeping: creation and modification dates help when you need to see which version of a file you have.
Frequently asked questions
Is my PDF uploaded?
No. The file is read in your browser using the pdf-lib library, which loads from a public CDN. Your document stays on your device.
Why are some fields empty?
Many programs leave fields such as subject and keywords blank. The viewer lists which standard fields are not set.
Can I open a password-protected PDF?
Files that only restrict printing or copying can be read. Files that need a password to open cannot be read in the browser.
