Change a PDF's title and author
The title stored inside a file is not the file name. A PDF called report.pdf can still show up as "Untitled 3" or as whoever first made it. Fix what is written inside.

Questions
No. This tool runs in your browser with JavaScript, so the file never leaves your device. Once the page has loaded you can even go offline and it still works.
Neither. No account, no watermark on the output. The practical limit is your device memory — large scanned files use more of it.
Guide: editing metadata well
When you'd use this
A PDF's title bar in a browser tab, the name a search engine or a reference manager shows for the file, and the author field a reader sees in "Document Properties" all come from metadata stored inside the file — not from the file name on disk. A report saved as report-final-v3.pdf can still display as "Untitled" or carry the name of whoever first created the template, because nobody updated the fields that actually control what is shown. This matters more than it looks: shared drives, citation tools and search results often display the stored title rather than the file name.
What can be changed
Four fields are editable: title, author, subject (a short description of what the document is) and keywords (a comma-separated list, useful for search inside large document libraries or content management systems that index PDF metadata). The tool shows the current values first, so you can see exactly what is stored before changing anything — useful for catching a leftover template name or a previous editor's identity that was never meant to go out with the final file.
Removing it instead of changing it
A separate "remove all metadata" action clears title, author, subject and keywords along with the producer and creator fields, which record which software made the file and are set automatically by whatever program exported it. This is the option to use before sharing a document where you would rather reveal nothing about its origin, rather than just update it to something else.
What this does not touch
Metadata is separate from the visible content of the page — changing the title field does not alter any text printed on the pages themselves, and removing metadata does not touch images, page content, or anything a reader sees when they open the file. For hiding visible content on the page rather than file properties, see Redact instead.
More questions
No — the file name on disk and the title stored inside the PDF are two separate things. This tool only changes the one stored inside the file.
The remove-all option clears the fields listed above; some PDF viewers also display creation and modification timestamps that are tracked separately and may need a different tool depending on how thorough the cleanup needs to be.
Many programs fill the author field automatically with the account name of whoever exported the file, without asking. That is almost always where an unexpected name comes from.
They do the same job; the server version exists for files too large to process comfortably in a browser tab.
