Free Online PDF Metadata Editor
Every PDF carries a small set of document properties — title, author, subject, and keywords — that appear in file managers, search results, and the "Document Properties" panel of PDF readers. These are often left blank, set to a generic filename, or carried over incorrectly from a template. LovePDFImg's Metadata Editor lets you read the current values and update them directly.
Changing metadata doesn't touch the pages of your document at all — it only updates the descriptive fields stored alongside the content. This is useful for giving a document a proper title before sharing it, crediting the right author, or clearing out leftover information from a source template. Everything is read and written locally in your browser; your file is never uploaded anywhere.
