Metadata Editor
About the Metadata Editor
The Metadata Editor tool lets you view and edit the descriptive information stored inside a PDF's document properties — Title, Author, Subject, Creator, and Keywords — the same fields you'd see if you opened a PDF's "Document Properties" or "Info" panel in any standard PDF viewer. This metadata doesn't affect how a page looks, but it plays an important role in how a document is identified, searched, and organized.
When you upload a file, the tool automatically reads and pre-fills the existing metadata values into editable fields, so you can see exactly what's currently stored before making any changes. You can then update the Title to something more descriptive than a generic filename, add or correct the Author field, write a Subject line summarizing the document's content, set a Creator value, or add comma-separated Keywords to improve how the file gets categorized or found in a search.
Accurate metadata matters more than many people realize: a well-titled PDF is easier to find later in a crowded folder or search index, a correct Author field matters for attribution and record-keeping, Keywords can improve discoverability in document management systems that index metadata, and a clear Subject line helps anyone previewing the file understand its content before opening it. This is especially valuable for organizations managing large document libraries, where consistent metadata conventions make a real difference in how quickly people can locate the right file.
It's also useful as a quick privacy check: PDFs sometimes carry over metadata from the software or account that originally created them — an author name you don't want attached to a public document, a generic "Creator" field revealing what software generated the file, or leftover Keywords from a template. Reviewing and clearing out unwanted metadata before sharing a document externally is a simple, often-overlooked step in preparing files for wider distribution. For a broader read on a file's technical details beyond just metadata, the PDF Info tool provides page count, file size, and page dimensions alongside the same metadata fields.
Before sharing a document externally, it's good practice to click through and review each metadata field even if you don't plan on changing anything, simply to confirm nothing unexpected — an old company name, a previous project's title, a personal note left in the Subject field from months ago — has been carried along without your notice. If you manage a shared document library, agreeing on a consistent Keywords convention across your team (for example, always including a project code and a document type) makes a real difference in how easily colleagues can search and filter your organization's files later, especially as the library grows past the point where anyone can remember every file by its name alone.
Because metadata changes are saved directly into a freshly generated copy of your PDF rather than modifying the original file in place, you can always go back to your unedited source document if you want to compare the before-and-after metadata, or if you decide you preferred the original values after all. This makes experimenting with different Title, Subject, or Keyword phrasing low-risk, since nothing about your original file is altered during the process.
