What this tool does

Set standard PDF descriptive properties such as title, author, subject and keywords. Make an internal reading copy easier to identify in document properties without rewriting the visible pages.

What you can open
One PDF and the standard document properties you want to set.
What you will download
One PDF with updated descriptive metadata.

How to use it

  1. Inspect existing properties if they matter to your workflow.
  2. Enter the new title, author, subject and comma-separated keywords.
  3. Download and check the document properties in a PDF reader.

Options explained

Title
Set the document title property; this does not change a visible page heading.
Author
Set the author property stored in document metadata.
Subject
Set a short subject property for the document.
Keywords (comma-separated)
Enter descriptive metadata keywords separated by commas. These are document properties, not a ranking guarantee.

Know the tradeoffs

  • Metadata changes do not edit titles or names printed visibly on a page.
  • Keywords stored inside a PDF do not guarantee search visibility or document ranking.

Questions about this tool

Will changing the title replace a page heading?

No. It changes a document property, not visible page text.

Can I clear standard metadata instead?

Use Remove metadata when you want the standard properties and XMP cleared.
