PDF metadata
Read and rewrite title, author and subject — or strip them.

What PDF document information is
The document information dictionary a PDF carries alongside its pages, defined in ISO 32000. Three of its fields are editable here — title, author and subject. They travel with the document, they are read by almost everything, and most people never look at them.
What this tool does that others do not
Read first, then rewrite
The fields fill with what your file already says the moment it opens. The author field is frequently a real name or a corporate username, and it travels: a CV exported from a work laptop can arrive at a new employer carrying the old one’s domain.
Cleared fields are written as cleared
Empty fields are written as empty rather than left at their previous value, which is the difference between stripping metadata and appearing to.
The software name is replaced, not kept
The producer field names the library that last wrote the file, and saving here replaces it with the library this tool uses, so the name of the software you exported from does not survive. The modification date is set to the time of saving.
How to use it
Open the file and read the fields
They fill as soon as the document opens. Seeing what is there is the point; most files carry something the author did not know about.
Clear the fields you want gone
Author most often identifies a person or an organisation. Title can carry an internal document name you did not mean to share.
Print to a new PDF as well if it really matters
This covers the standard document information fields, which is what nearly everything reads — but not XMP packets embedded by some producers, nor per-object metadata.
Worked example
Real input, real figures.
A CV about to be sent to a new employer
You give it
A PDF exported from a work laptop.
You get
The author field commonly holds a corporate username. Clearing it and downloading writes it as empty, and the producer is replaced on save, so the copy you send carries neither.

Guide
What your PDF says about you
PDFs carry metadata most people never look at: title, author, subject, and the name of the software that produced them. The author field is frequently a real name or a corporate username, and it travels with the document — a CV exported from a work laptop can arrive at a new employer carrying the old one’s domain.
Open your file and the title, author and subject fields fill with what it already says. Clear them and download to strip them. Saving also replaces the producer with the name of this tool’s PDF library, so the software you exported from is not named in the copy you send. Keywords and any XMP block are left as they were.
Questions people ask
Straight answers. Each one links directly: copy the address after opening it.
How do I remove metadata entirely?
Open the file, clear the title, author and subject fields, and download. Empty fields are written as empty rather than left at their previous value, and the producer is replaced on save. Keywords and XMP are not rewritten; for a document where that matters, print to a new PDF as well.
Does this remove everything identifying?
It covers the standard document information fields, which is what nearly everything reads. It does not rewrite XMP packets embedded by some producers, nor per-object metadata. For a document where this genuinely matters, print to a new PDF as well.
Why does Producer say something I have never used?
It names the library that wrote the file, not the application you used. Many applications use a shared PDF library underneath. After saving here it names this tool’s library instead.
Nothing leaves your device
Your file is read into this tab and worked on there. It is never uploaded, which is why there is no queue, no daily limit and no account, and why the tool still works with the network switched off.
