Every PDF carries a small block of information about itself, separate from anything printed on its pages. Most people never see it, and most people would be surprised by what is in theirs.
Title is what a reader shows in its window title bar and tab, and what many document management systems index and display in listings. When it is empty, software falls back to the filename. When it is wrong — and it very often is — it shows something misleading in every list the document appears in.
Author is filled in automatically by whatever produced the file, usually from the operating system account name of the person who created it. This is the field that most often carries information nobody intended to send.
Subject is a one-line description, useful for archives and search.
Keywords is a comma-separated list — invoice, q4, 2026 — that indexers and desktop search read.
Beyond those, a PDF records the software that produced it and the dates it was created and last modified. Saving here sets the modification date to now, preserves the original creation date, and keeps the producer and creator fields unless you edit them.
Metadata leaks. Not dramatically, but routinely, and in ways that are awkward once noticed.
A CV exported from a shared machine that names a different person as author. A proposal whose title is still Copy of Acme proposal v3 FINAL (reuse for Beta Corp), sitting in the tab bar while your client reads it. A tender document whose author field names a colleague who left two years ago. A supposedly anonymous submission carrying the submitter's full account name. None of these appear on any page, and all of them travel with the file.
It costs about fifteen seconds to look. Load a document here before it goes outside your organisation and you can see exactly what it is carrying, which is the entire argument for making this a habit on anything client-facing, legal, or competitive.
It is also worth pairing with the other place information hides: Redact PDF for content on the page that must be removed, and a sensible filename, which no tool can fix for you and which is read before anyone opens the document.
Metadata belongs to the document rather than to its pages, so document-level operations tend to reset it. A merged file inherits properties from the first document in the stack, which is usually somebody else's. Split outputs inherit from the source. Conversions from Word, Excel or PowerPoint carry whatever the source file recorded.
So set properties last, once the pages have stopped moving. Assemble the document, number it, then set its title and author as the final act before sending. Two minutes of work that makes an archive genuinely searchable years later.
Flatten PDF, Compress PDF and Protect PDF all preserve properties, so those steps can happen either side of this one.
It gives you direct control over the standard document properties — title, author, subject, keywords — and lets you review and edit the producer and creator fields, and sets the modification date on save while preserving the original creation date. That covers the fields that actually leak identifying information in practice. Content printed on the page is a separate matter: Redact PDF removes that.
One document per run, which keeps the tool honest about showing you each file's existing values before you change them — the reviewing is usually the point. For a batch, running them in sequence takes a few seconds each.
Comma-separated, like invoice, acme, q4, 2026. Spaces around the commas are fine. Use the terms you would actually search for later; a focused handful is more useful than an exhaustive list.
The modification date is set to the moment you save, which is accurate — the document genuinely was modified. The producer and creator fields are shown for you to keep or change, and the original creation date is preserved.
No. Metadata lives in the document's information dictionary, entirely separate from page content. Text stays selectable, images keep their resolution, form fields keep working, and the file size barely moves.
Merged documents inherit their properties from the first file in the stack, which is often a document somebody else produced. Setting them here after merging is the fix, and it is worth making the last step of any assembly job.
Unlock it first with Protect PDF, edit the properties, then re-apply the password with the same tool.
No. The PDF is read and rewritten inside this browser tab, and the result goes straight to your downloads. Since the reason to open this tool is often to check what a confidential document is carrying, that matters — go offline first and it still works.
Privacy: Metadata reading and writing run locally with pdf-lib. The file never leaves your device, and no metadata is logged on our side.
