Edit Metadata

PDF metadata is the hidden information attached to a document — its title, author, subject and keywords. Correct metadata makes files easier to search, organise and identify, and looks more professional when the document is opened.

ColaPDF lets you view and edit these fields directly in the browser. This is useful for removing an author name before sharing, or setting a proper title so the document displays correctly in viewers and search.

How it works

1. Upload your PDF — existing metadata is loaded automatically
2. Edit title, author, subject, keywords and creator fields
3. Click Save Metadata
4. Download your updated PDF

Tips

• Clear the author field to remove your name before sharing a document publicly.
• A descriptive title helps the file show up correctly in document viewers and search tools.
• Keywords improve how the document is found in document-management systems.
