Read and rewrite what a PDF says about itself: title, author, subject, keywords, the application that created it, the application that last touched it, and the creation and modification dates. Set a professional title, replace a name that should not be there, or erase everything. The changes are written into the file's document information dictionary properly rather than being hidden behind a viewer. No upload, no sign-up, no watermark, and it works offline.
To edit PDF metadata free, add the file to see its current title, author, subject, keywords, creator, producer and dates. Change any field or erase them all, then download. Nothing is uploaded and there is no sign-up.
The exporter had no title to write, so it used a default, and that default is now what a file manager and a search index show. Set the title to the document's real name. It takes five seconds and it is the first thing a recipient sees in a list of downloads.
Exporters default the author to the operating system's user name, so a laptop called 'Ravi-PC' can leave a name and a machine hint in every document it produces. Clear the author, the creator and the producer, and set the creator to something neutral if the field must be filled.
A real title and a language tag are the two fields that matter most, because they are what a screen reader announces and what a browser uses to pick a pronunciation. Both are editable here, and both are worth more than a page of visual polish.
The producer string and the timestamps reveal the tool and the moment a document was created, and a mismatch between them is a classic sign of a file that has been assembled from several sources. If you are assessing a suspicious document, the metadata is the first cheap thing to look at.
A dictionary in the file describing the document: title, author, subject, keywords, the application that created it, the one that last modified it, and creation and modification timestamps. A PDF opened in a file manager often shows a title and an author that the person who exported it never consciously set.
Because the exporter copied it from a template, a previous version, or the machine's user account. Word and LibreOffice both carry the operating system's user name into the author field by default, and a document passed through several people's machines can accumulate a surprising history.
No. The title metadata and the filename are separate, and some systems display the title from the metadata in preference to the filename. If you want both to agree, rename the file as well — a document whose title and filename disagree confuses whoever receives it.
The field can be cleared, but note that many writers set it again to the moment the file is written. The practical approach is to set a meaningful date rather than trying to have none — a professional date is better than an obviously falsified or absent one.
No. Metadata is the document information dictionary. Hidden data is broader: comments, tracked changes, form values, invisible text, embedded files, layers and scripts. Privacy Scanner covers all of those; this tool is for the document properties specifically.
Keywords in the metadata are read by some document management systems and by search engines that index PDFs. It is worth setting three to six real phrases. Do not stuff it — a keyword field with forty terms tells a reader nothing and looks like spam.
No. The content streams are untouched; only the information dictionary is rewritten. Page content, text and images are unchanged, which is why the operation is fast and lossless.
Yes. Free, no account, no watermark, and no upload. Editing properties is one of the smallest possible reasons to send a document to a stranger's server.
