Edit PDF Metadata — Update Title, Author and Subject
Change the title, author and subject fields stored inside a PDF. These fields show up in search results, in the browser tab when the PDF is viewed online, and in file managers — so getting them right matters for professionalism and SEO.
Why metadata matters
The Title field is what shows in the browser tab and Google search results when a PDF ranks. A file called "final_v3.pdf" with an empty title looks amateurish; a proper title looks intentional.
What gets updated
Title, Author, Subject and the modification date. The file's content, layout and other metadata (creator, producer, creation date) are left alone.
Frequently Asked Questions
Will this change the filename on disk?
No. The filename you download is up to you; only fields inside the PDF are changed.
Can I edit keywords too?
This tool covers the most common fields (title, author, subject). Keywords and custom XMP metadata need desktop software.
Does it work on encrypted PDFs?
Unlock the PDF first — the metadata editor needs write access.
