What a PDF says about the people who made it
The author field is usually filled in automatically from the name on the computer or the office suite's account, which is how a report written for a client ends up naming the junior analyst who drafted it, or a “neutral” document names the organisation that really wrote it. The Creator and Producer fields name the software and often its exact version. Creation and modification dates are stored with a time zone, which can place the author on a map.
XMP metadata can say much more. Many publishing and office programs record an editing history in it: each save, with the date, time and the application that did it. It also carries permanent document IDs that link a file to every other version derived from it — the redacted copy and the original included.
Then there is metadata nobody thinks of. A PDF made from phone photos — a scanned receipt, a photographed form, a property report — embeds those photos as JPEG files, and a JPEG can carry its own EXIF block with the camera model and the GPS coordinates of where it was taken. Comments carry the name of whoever wrote them. This tool reads all of these and shows them before anything is changed, with the identifying ones marked.
What removal removes
The document information dictionary is deleted outright: title, author, subject, keywords, creator, producer, both dates and any custom properties such as Company. The catalog's XMP packet goes, along with XMP attached to individual pages and images, and the private data some programs store for themselves in PieceInfo entries.
Inside embedded JPEG photos, the EXIF, XMP, IPTC and comment segments are cut out byte for byte. The compressed image data is copied through untouched, so the photos lose no quality, and the colour profile is kept so their colours do not shift. Author names and dates are cleared from comments and markups, while the comments themselves remain.
Two less obvious steps finish the job. The document ID is replaced with a random one, so the clean copy cannot be matched to other versions by it. And every object no longer referenced by the document is dropped. PDFs that have been edited and saved incrementally keep the previous versions of changed objects in the file, so an old information dictionary naming the original author can survive below the current one; it does not survive this.
What metadata removal cannot remove
Anything that is the document itself. A name typed on page one, a signature image, a letterhead, the text of a comment, the answers in form fields — none of that is metadata, and all of it stays. Read the pages before you send them, and use Redact PDF to remove content that must not be seen.
Hidden layers stay too. A PDF exported from a design or CAD program can contain optional content layers that are switched off, with drafts, notes or alternative versions inside; turning a layer off hides it, it does not delete it. Attached files stay, and they carry their own metadata. The names in digital signature certificates stay, because removing them would break the signature anyway.
The tool lists which of these it found in your file, so you know exactly what is left, rather than being told the file is “clean” when it is not.
Checking the result
After cleaning, the new file is read back with the same code that read the original, and the panel shows what remains: no document information, no XMP, no photos with EXIF and no comment authors. That check is a measurement of the output, not a promise.
You can confirm it independently. Open the clean file's Document Properties in any reader — the title, author and dates should be blank — and the pages should look exactly as before, because nothing on them was changed.
This is the PDF counterpart of Remove EXIF Data, which does the same for photos: both show you what the file reveals first, because the most useful thing a metadata tool can do is tell you what you were about to send.
Answers
Frequently asked questions
Does removing metadata change how the PDF looks?
No. Only information about the document is removed; the pages, their text and their images are copied through unchanged.
Can a PDF reveal where a photo was taken?
Yes, if it contains photos that kept their EXIF data. The tool shows any GPS coordinates it finds and strips them without re-compressing the photos.
Will this remove names written on the pages?
No. Text on the page is content, not metadata. Use Redact PDF to remove it.
Are earlier versions of the document removed?
Objects left behind by earlier incremental saves are dropped, so an old author name stored in a superseded version does not survive.
How do I know it worked?
The clean copy is read back and the remaining metadata shown. You can also check Document Properties in any reader.
Is the file uploaded?
No. The file is inspected and cleaned in your browser, which matters more for this tool than almost any other.
