What a reader shows in its window bar and what most search tools index ahead of the filename.

Word fills this in from the licence holder's name, which is how documents leave an office carrying somebody's full name.

A one-line description. Rarely displayed, frequently indexed.

Separate them with commas. They are stored as a list, which is what document management systems read.

Empties every field, including the producer and creator lines you cannot type into, before writing anything above.

    How it works

    Every PDF carries a document information dictionary — a small set of entries naming the title, the author, the subject, the keywords, the program that produced the file and the one that created the content. The document is parsed, those entries are read and reported, then the ones you filled in are written back and the file is saved. An empty field means leave that entry alone, because the form is built from this tool's own settings and cannot be filled from a document it has not been given yet.

    What to watch out for

    An empty field keeps what is there rather than clearing it

    The panel cannot show you the current values before you choose a file, so a blank box can only mean "not specified". Clearing is therefore a separate switch, and it runs first — which lets you empty a document completely and then set one honest title in a single pass.

    XMP is a second copy, and this one is not it

    Many producers write the same information twice, once in the dictionary this edits and once as an embedded XMP packet. Readers usually prefer the dictionary, but a document management system may well read the packet instead, so a file cleared here can still show an old author somewhere else.

    It says nothing about who made the pages

    Metadata is a description attached to the document. Text in the pages themselves, a letterhead, a scanned signature and the identifiers a scanner writes into an embedded image are all untouched. This changes what the file says about itself, not what is printed on it.

    Limits

    Files up to about 200 MB work reliably. Beyond that, the ceiling is your device's memory rather than any rule we impose — the work happens on your own machine. Tested in Chrome 140, Firefox 143, Safari 18.

    What a PDF is telling everyone

    Open a document’s properties in any reader and there is a small panel most people never look at. It usually has a name in it.

    Word writes the licence holder’s name into the author field, so a contract sent to a client can arrive carrying the full name of whoever happened to have the template open. The producer line names the software and often its exact version. A file that began as a scan carries the model of the scanner. A title field left over from a template can still say “Untitled document 3” or, worse, the name of the previous client the template was used for.

    None of it appears on any page. All of it travels with the file.

    Reading before writing

    The result reports which fields were set before this ran and what produced the document, which makes this useful even when you change nothing: it answers the question of what a file has been disclosing.

    The producer line is worth a glance in particular. It is the entry nobody thinks to edit and the one that most reliably says where a document came from.

    Clearing, and then setting

    The switch empties everything, including the producer and creator entries that have no box to type into. It runs before the fields above it, so the natural sequence for a document about to be sent somewhere is one pass: clear it all, and give it the title you would like a reader to display.

    Opened here, not uploaded

    The document is parsed and rewritten by a Web Worker inside this tab. For a tool whose whole subject is what a file quietly says about the person who wrote it, sending that file to somebody else’s server first would be a strange way to begin.
