When to edit PDF metadata
Set a proper title so browser tabs and search results show something meaningful. Fix author attribution before forwarding. And before a document goes public, wipe the creation trail — usernames, editor history, timestamps — that metadata quietly carries.

Frequently asked questions
What metadata does a PDF contain?
Title, author, subject, keywords, creator application, and creation/modification dates — plus, in some files, producer trails and edit history.
Does wiping metadata affect how the document looks?
No. Pages, text, and images are exactly the same — only the information-about-the-information changes.
Why wipe metadata before sharing?
Metadata can leak your username, software versions, working hours, and organizational structure. Stripping it is standard hygiene for anything leaving your circle.
Will the title show in browser tabs?
Yes — most browsers and readers display the PDF title field. Setting it makes shared documents look professional.
Can I edit metadata of a scanned PDF?
Yes. Scanned or digital, the metadata layer is the same and edits apply the same way.
Is my file or its metadata uploaded?
No. Reading, editing, and writing all happen locally in your browser.
