How to Find Out Who Created a PDF (and How Much to Trust It)
Received a PDF and want to know who made it? Here is how to check its author, creator app, producer and dates — and what that metadata can and cannot prove.

Quick answer
Most PDFs carry a small block of document information: Author, Title, Creator (the app that made the original), Producer (the software that wrote the PDF) and creation and modification dates. You can read these in any PDF reader's properties panel, or upload the file to our free metadata viewer to see them in one report — no account needed.
Treat what you find as a clue. Metadata records what software saved, and anyone can edit or delete it.
Where the "who made it" information lives
A PDF can store identity details in two places:
- The document information dictionary — the classic Author, Creator, Producer and date fields.
- XMP metadata — an XML block that can repeat those fields and add more, such as a tool history.
The two do not always agree. If a sender cleared one but not the other, a viewer that reads both can still reveal a name. Our guide to removing PDF metadata explains why this matters when you send PDFs yourself.

Method 1: check the properties in your PDF reader
- Adobe Acrobat or Reader: open the file and choose File > Properties. The Description tab shows Author, Creator, Producer, Created and Modified.
- Mac Preview: open the PDF and choose Tools > Show Inspector, then the info tab. Apple documents how to view PDF document info in Preview.
- Browsers: Chrome and Edge show a "Document properties" option in their PDF viewer menu on many versions.
This is fast, but reader panels often hide XMP-only fields.
Method 2: use a metadata viewer for the full picture
Upload the PDF to the upload box. The report lists every field we detect, including names that only appear in XMP, the producer software, and any dates. Viewing is free; you only need an account if you want to clean and download a file.
How to read what you find
| Field | What it usually means |
|---|---|
| Author | The name set in the app that made the original, often the computer's account name |
| Creator | The app used to write the source, such as Microsoft Word |
| Producer | The PDF engine, such as a print driver or export library |
| Created / Modified | When the PDF was written and last saved |
An Author of "jsmith" plus Creator "Microsoft Word" suggests the PDF was exported from a Word file on a computer whose user is jsmith. It does not prove jsmith wrote the words.
Why the author can be blank or wrong
- The sender removed metadata before sharing.
- The PDF came from a scanner, which often writes only the device name.
- A web service generated the file and inserted its own name.
- Someone edited the fields by hand.
If the details matter — for example in a dispute — keep the original file unchanged and seek professional forensic advice. Our article on metadata in legal discovery covers why originals matter.
Sending a PDF yourself?
The same fields that tell you about a sender tell recipients about you. Check your own file in the viewer, then clean it: you can clean and download one file free — once per account, and Pro is $14.99/year for regular use. See also how to see who wrote a Word document.
