Edit PDF Metadata Online — Modify Title, Author, Subject, Keywords

The Metadata tool at PDFGuru lets you read and modify the internal document properties of any PDF. These properties — title, author, subject, keywords, creator and producer — are normally hidden inside a small XML structure embedded in the PDF file. They appear in document viewers like Adobe Reader, Apple Preview, Foxit Reader and Microsoft Edge as the "Document Properties" dialog when a reader presses Ctrl+D.

When sharing PDFs across an enterprise, these metadata fields serve important purposes. They help file indexers cluster content by topic; they let search engines rank documents accurately; they appear as descriptive info windows in directory listings; they help legal teams demonstrate provenance and credit authorship. Often however, the metadata set by the original creator is inaccurate, incomplete or even harmful — embedded author names after content rewrites, personal email addresses left over from drafts, project codenames that should not be exposed externally.

PDFGuru reads the existing metadata automatically when you drop the PDF onto the dropzone. You can then erase, edit or complete any of the fields and click "Save Metadata" to produce a new PDF with your overwrites applied. The text content and structure of the document are untouched — only the metadata XML is modified.

This tool is particularly valuable for legal teams redacting privileged authorship, executives preparing press releases, students publishing thesis portfolios, auditors anonymising corporate documents, or anyone who wants to rebrand legacy documents before archive. All operations happen inside your browser tab — there is no upload, no third party, no server-side copy.

Try the metadata tool above — there is no signup, no quota, no file-size limit and absolutely no upload. Modify your PDF metadata in seconds and download the result.

PDF Metadata — Frequently Asked Questions

Title, Author, Subject, Keywords, Creator and Producer — the six most widely-recognised fields. Creation date and modification date are also supported internally and surfaced on save.
No. The visible content stream, embedded fonts and image layers remain identical. Only the descriptive metadata XML document is rewritten.
PDFs produced by different tools embed different metadata fields. Some authors skip the Subject and Keywords fields entirely; pdf-lib reads what was present and pre-fills those fields as empty strings.
Erasing the Author, Creator and Producer fields removes them from the standard XML dictionary. For maximum anonymity we recommend combining this tool with a pass through the Compress tool to re-package the file structure from scratch.
