You can edit PDF metadata for free without uploading the file to a server. Inkfolio changes the hidden document details entirely on your own device.
What PDF metadata actually is
Every PDF carries hidden information beyond what’s visible on the page — the document’s title, author name, the software that created it, and creation or modification dates. This metadata doesn’t show up when you open the file, but it’s stored inside it and visible if someone checks the file’s properties.
Why it matters more than people realize
Metadata can reveal more than intended: an author field showing a company’s internal username, a creation date that contradicts a document’s supposed timeline, or software details that hint at how a file was produced. For documents you’re sharing externally, checking and cleaning up metadata is a small but meaningful privacy step.
Step-by-step: editing PDF metadata
- Go to Inkfolio’s Edit Metadata tool
- Upload your PDF
- View the current metadata fields
- Edit or clear the title, author, subject, and other fields
- Download your updated PDF
What fields you can typically change
- Title — the document’s name as stored internally (separate from the filename)
- Author — who created the document
- Subject — a brief description of the content
- Keywords — tags associated with the document
- Creator/Producer — details about the software used to make the PDF
A quick honest note on what metadata editing doesn’t do
Editing metadata changes the document properties, not the visible content of the pages. If sensitive information is written directly in the document text (not just the hidden metadata), metadata editing won’t remove it — that’s a job for redaction instead.
How to check what metadata is already in your file
Before editing, it helps to see what’s actually there. Most PDF viewers show document properties under a menu like “File > Properties” or “Document Info,” which lists the title, author, creation date, and other fields exactly as they’re currently stored. Checking this first tells you whether there’s anything worth changing before you start editing.
Common situations where editing metadata matters
- Removing a company or personal name from the author field before sharing a document externally
- Fixing an incorrect title that shows up when the file is shared or indexed somewhere
- Clearing software details that reveal what tool created the document, if that’s not something you want visible
- Standardizing metadata across a batch of documents so they’re consistent when archived together
Does editing metadata affect the document’s content or appearance
No. Metadata exists separately from the visible pages — changing the author field or title doesn’t alter any text, images, or formatting on the actual pages. The document looks and reads exactly the same; only the hidden properties change.
Metadata and search or file organization
Some systems (document management software, certain search tools) index files partly based on their metadata title and keywords rather than just the filename. If a PDF’s internal title doesn’t match its actual content, it can show up with a misleading or outdated name in these systems — updating the metadata title to match the real content keeps things easier to find later.
Metadata that gets added automatically
Even if you never touch the metadata fields yourself, most PDF-creation tools fill some of them in automatically — the software name in the Producer field, a creation date matching when the file was generated, and sometimes a default author name pulled from your device or account settings. This is why a document you never manually labeled can still show identifying details when you check its properties; the fields were set behind the scenes, not by anything you typed.
