- 1Drop in a PDF

- 5Nothing is changed — the file is only read
What PDF Metadata Viewer does
Every PDF carries a set of document properties that no reader shows you by default. Some are innocuous — the page count, the creation date. Others record who made the file and what with, and they are filled in automatically by whatever produced the document, usually without the author ever seeing them.
That matters because those fields travel with the file. A CV exported from a word processor commonly carries the account holder's real name in the author field even when the document itself uses another; a report assembled from a template often still names whoever created the template years earlier.
When to use it
- Checking a document before sending it
- The author field is populated from your operating system or application account. It is worth knowing what it says before a CV or a tender submission goes to someone you have not met.
- Working out what produced a file
- The producer field names the library or application that wrote the PDF, which often explains why a document behaves oddly in one reader and fine in another.
- Establishing when a document was made
- The creation date is set when the file was generated, independent of the filesystem timestamp, which resets whenever the file is copied or downloaded.
- Verifying a document you received
- A contract claiming to date from last year, produced by software released this year, is worth a second look. Metadata is not proof, but a mismatch is a signal.
PDF Metadata Viewer settings explained
- Title and subject
- Free-text fields set by the producing application, often left empty or filled with something unhelpful like the template name. When present, the title is what some readers show in the window bar instead of the filename.
- Author
- The field most likely to identify a person. It is usually populated automatically from the account name of whoever exported the file, not typed deliberately, which is why it so often contains a real name unintentionally.
- Creator
- The application the document was authored in — a word processor, a design tool, a scanner's software. This describes where the content came from.
- Producer
- The library or engine that actually wrote the PDF bytes, which is frequently different from the creator. A document authored in a word processor and printed to PDF names one in each field.
- Creation date
- When the PDF was generated, stored inside the document. Unlike the filesystem date, it survives copying, emailing and downloading.
Creator or Producer
| Field | Describes | Typical value |
|---|---|---|
| Creator | Where the content was authored | A word processor or design application |
| Producer | What wrote the PDF file itself | A PDF library or print driver |
Limits and what to expect
- This tool reads metadata; it does not remove or edit it.
- Fields left empty by the producing application show as a dash — most PDFs fill in only some of them.
- Only the standard document properties are shown, not the XMP packet some applications also embed.
- Metadata is trivially editable, so it is an indication of provenance rather than evidence of it.
- Documents requiring a password to open cannot be read; permission-restricted ones are fine.
Troubleshooting
- Every field shows a dash
- The document has no metadata, which is normal for PDFs produced by minimal libraries or deliberately stripped by a privacy tool. An absence of fields is itself informative — it usually means the file did not come from an office application.
- The author is not me
- The field carries whoever's account produced the original, and it survives editing and re-saving. Documents built from a downloaded template very often still name the template's author years later.
- The creation date does not match when I made it
- It records when the PDF was generated, not when the content was written. A document drafted over weeks carries the date of the export, and a file re-saved by another program may carry that program's date instead.
- How do I remove this metadata?
- This tool only reads. Passing the document through an operation that rebuilds it — merging, extracting pages, splitting — produces a new file without the original properties, which is the simplest route to a clean copy.
Your files and your privacy
The document is read inside your browser and the properties are displayed on your device. Nothing is uploaded, which would rather defeat the purpose: a tool for finding out what a file discloses about you should not be the thing that discloses it. Your file is not modified — this reads only.
What to use next
FAQ
What metadata does a PDF contain?
The standard document properties are title, author, subject, keywords, creator, producer and the creation and modification dates. Applications fill these in automatically when they export, and most people never see them because readers do not display them by default.
Can a PDF reveal who made it?
Frequently, yes. The author field is usually populated from the account name of whoever exported the file rather than typed deliberately, so it often carries a real name. The creator and producer fields also reveal which software and version were used.
What is the difference between creator and producer?
Creator names the application the content was authored in — a word processor, a design tool. Producer names whatever actually wrote the PDF file, usually a library or a print driver. A document written in one program and exported through another shows a different value in each.
How do I remove metadata from a PDF?
Not with this tool, which only reads. Running the document through an operation that rebuilds it — merge, split, or extract pages — produces a new file that does not inherit the original properties.
Is the creation date reliable?
It is an indication, not proof. Metadata can be edited with ordinary tools, so a date should be treated as a signal rather than evidence. A mismatch is more informative than a match: a document dated before the software that produced it existed is worth questioning.
Is my document uploaded?
No. It is read inside your browser on your own device, and the tool works with the network disconnected.
