PDF metadata is the behind-the-scenes information stored in a document, such as its title, author, subject, and keywords. Most people never look at it, yet it shapes how files appear in search results and in your document library. This tool shows you exactly what metadata a PDF currently holds and lets you rewrite it, all inside your browser with no uploads and no servers involved. Your original file stays on your device, and the updated version downloads as a separate copy.
When you search a folder full of PDFs, the file name is only part of the story. Many applications read the document's title and keywords to build search indexes, previews, and file listings. A PDF titled "Document1" with no author is hard to find later; the same file with a clear title, author, and keyword list slots neatly into any organized library and comes up the moment you type a related term.
Metadata also matters when you publish or share. A report that identifies the wrong author, or none at all, looks unfinished to readers, and a missing title can make an attached file display as an anonymous blob on the other end of an email. Correcting these fields takes seconds here, without opening a heavy desktop application or sending your file anywhere.
The editor works with the four standard fields most tools recognize. The title is what shows up in browser tabs and file listings. The author identifies who created or last edited the document. The subject gives a short summary of what the file covers. Keywords, entered as comma-separated terms, help search tools and indexers categorize the document so it surfaces in the right context.
When you select a PDF, the tool reads its current values and pre-fills the fields, so you can see what is already there before changing anything. Fields you leave blank simply stay unset in the output rather than being forced into some default. That matters when you want to tidy one field without accidentally stomping on another.
The whole operation takes a few seconds for a typical document. Because the reading and writing both happen locally, you can update a hundred internal files without ever putting a single one on a network.
Keep in mind that this editor handles the standard property fields only. Deeper hidden data, like embedded software names or annotation layers, lives elsewhere in the file and is not part of this tool's scope. For cleaning out those deeper traces, you would use a dedicated sanitizing tool instead.
Updating metadata is most useful when you adopt it as a routine. Before you file a finished document, give it a title and author. Before you email an attachment, confirm the subject line makes sense. Those few seconds keep your library findable and make every file you hand off look intentional.
Pro tip
Pick keywords the way a search tool would — short, specific terms someone might actually type, rather than full sentences. A handful of accurate keywords does more for findability than a long list of vague words, and it keeps your metadata readable instead of cluttered.
Editing metadata is free for files up to 10MB, with a brief wait between runs on the free tier. Premium subscribers skip that wait, process files up to 100MB, and can work through several documents in a batch. Because the entire operation runs in your browser, confidential drafts and internal documents never leave your machine, which makes the tool a safe fit for compliance-sensitive material.
