PDF Metadata: a practical guide

PDF metadata is the information a reader shows in its title bar and a search engine uses to index the file. Editing it after the fact, without reopening the source document, fixes a wrong title or a missing author before the file is sent out. The page content is not affected.

How to use it: Open the PDF you want to update. Then Fill in the fields you want to change (title, author, etc.). Then Click "Apply Metadata" and wait. Then Download the updated PDF..

Edit title, author, subject. Change keywords for search. Works on encrypted PDFs (after unlock). No reformatting of content.
