PDF Metadata Editor

A PDF metadata editor shows and changes a PDF's document properties: title, author, subject and keywords. This one reads the current values, lets you edit them and saves an updated copy with the pages unchanged. It runs in your browser; downloading needs a free account.

A PDF's metadata is a small set of fields — title, author, subject, keywords — that don't appear on the page itself but show up in file browsers, PDF reader "document properties" panels, and search indexes. Left unedited, these often default to whatever a scanner or export tool auto-filled: a generic "Untitled," the wrong author name, or nothing at all.

This tool loads your PDF's current metadata, lets you view and edit each field, and saves an updated copy. Correct metadata matters more than it seems: a properly titled and authored PDF is easier to find later in a folder of similarly-named scans, search engines can index it more usefully if it's ever published online, and a professional document with the right author name looks more polished when a recipient checks its properties.

It's also useful defensively — removing metadata that leaked from an internal template (an old company name, a previous author who's since left) before sending a document externally. As with every tool in this suite, your file is read and edited entirely in your browser; the metadata you're viewing is never transmitted anywhere.

A quick pass with this tool before publishing or sharing a PDF externally takes seconds and closes off a small but real source of accidental information leakage. Pair it with Compress PDF, which also strips redundant metadata as part of its structural cleanup, if file size is a concern too.
